Do you filter your water before consuming, if so for what contaminates/additives?  How about your shower?

I find it funny that the United States has one of the best public water systems in the world, with the cleanest tap water available, and people still get worked up about it. Your drinking water is better than what 80% of the world's population has access to, unless you are not on a public system. Marketing people drive our concern about it to sell more shit to you.

 

The chloride is in small amounts that are part of the purification process. And flouride, in proper concentrations, actually helps your teeth and doesn't hurt you.

I grew up with well water.  I can't stand the taste or smell of chlorinated water.  There is no way that water that smells like that can be completely healthy.

It may be your preference, but it is far more likely that your unprocessed well water was more harmful than the public water available. The EPA requires constant monitoring of  the public system for contaminants and remediation of the water is adjusted based on the results. The chloride may smell funny to you, but it is eliminating bacterial content that could be harmful, which the well water you drank may have contained. 

 

Personally, the chlorination doesn't bother me...

Depends I guess on how much you trust those "safe" levels of poisons that the Gov says are acceptable.

Of course those levels change based on such scientific evidence like what party happens to be in office, but hey, follow as you will.

I really should use a filter for the shower...at least in the winter. CL is so prevalent in my water it smells like a swimming pool.

Long Island uses lime and chlorine as part of the purification process...

Hi

 

is there evidence that drinking fluoride is good for teeth? If so, that doesn't convince me that it's safe for the rest of me.

 

edit: from what I'm reading there is a claim that applying it to teeth can help enamel but adding it to water does nothing to help. Hold that thought, reading more sites...some saying it does help... but this makes sense and have heard this in the past:

 

1

I had wondered by what mechanism fluoride was supposed to help prevent cavities so I asked my dentist. Enamel is made of hydroxylapatite, Ca5(PO4)3(OH), and the fluoride ion can replace the hydroxy (OH) group. The fluoride ion makes a tighter bond than a hydroxy group, leading to a more stable compound, more resistant to acid secreted from tooth bacteria. You can think about the reason why fluoride generally isn't so good in the rest of the body is because of that same bond strength. Fluoride really wants to form bonds, so it can disrupt other biological reactions in the body. My dentist thought that ingesting fluoride wasn't helpful for our teeth, but taking a fluoride rinse is helpful for people prone to cavities who didn't have fluoride when they were developing their teeth. The idea is, fluoride would be beneficial systemically during tooth formation in infants so that much of the enamel is created with the stronger fluorapatite. But after the teeth are developed (which happens before they break through the gum), systemic fluoride doesn't help. If you didn't get fluoride at that time period, then as an adult, if you're prone to cavities, you might find topical fluoride useful because it can be used in your enamel as it gets remineralized to form the fluorapatite instead of the hydroxylapatite. (Remember that, like bones, teeth are in a constant flux of demineralizing and remineralizing, dependent on pH and other factors.) But because it's only ever on the surface, it would require repeat applications. At least, that's the theory as I understand it from my conversation with my dentist."

Don't get me wrong, I am not particularly happy with changes in legislation that lower water quality standards. I am also unhappy with the amount of funding allocated for public water system maintenance and improvements. Our aging infrastructure is not getting the attention it is due.

 

But, even with these issues, our water supply is one of the best in the world, and I think we complain about it too much.

 

People in Africa still have to walk for miles to contaminated sources to get their drinking water. We are pretty lucky.

Ok, watched the whole video. 

 

I find his arguments very interesting. I would rather have heard more about the researcher's findings at the end about how fluoridation can lead to a lower IQ. I also think they focused too much on the damage caused by high levels of fluoride, which is a side argument since people generally agree that high levels are damaging

 

While it is easy to see that fluoridation at high levels is damaging, I still don't feel they have proven their argument on this 60 year old issue. My personal perspective is that, at this time, the benefits out weight the potential, unproven harm.  

 

I do appreciate the video's arguments that our understanding of things change over time, i.e. asbestos, cigarettes, etc, and I do have an open mind about it. For instance, I read this article the other day about the impact of lead in gasoline being tied to crime rates...

Community Water Fluoridation in the United States Policy Date: 10/28/2008 Policy Number: 20087

Community Water Fluoridation in the United States

This position paper provides updated evidence for the many supportive policies held by the American Public Health Association (APHA) on community water fluoridation (CWF). This position paper provides the scientific basis and justification for the importance of continuing to support CWF for our nation’s public water supplies. It also emphasizes the critical role that public health practitioners, health care professionals, and policymakers can play with respect to this important public health practice. The position paper will enable APHA to continue as a policy leader for CWF and safe drinking water. The objectives of this position paper are for APHA to be well positioned to—

• Provide expert guidance to regulatory agencies on decision-making regarding CWF standards and regulations; • Improve public health education about the safety and efficacy of CWF, specifically education for public health and other health professionals, decision makers, and the public; and • Promote sufficient funding for federal, state, and local CWF programs.

Relationship to Existing APHA Policies The following APHA policies are updated and replaced by this position paper and are archived with the adoption of this resolution: 5005, 5508, 5904, 6912, and 7402.

The Problem Tooth decay (dental caries) is one of the most common diseases in our country, affecting almost the total population. Although the scientific evidence base supports CWF as the foundation for improving a community’s public health by minimizing the prevalence and severity of tooth decay, many communities have not successfully initiated or continued this public health measure.1–4 Those opposed to fluoridation sow doubts about the risks and benefits of CWF, often with little scientific basis. In addition, there is often insufficient advocacy for CWF in the face of ongoing media campaigns by activists opposed to fluoridation, commonly referred to in the literature as antifluoridationists.2

Support for CWF Since 1950,5 APHA has supported CWF as a safe and effective public health measure for the prevention of dental caries (tooth decay), reaffirming this policy in 1955,6 1956,7 1959,8 1963,9 1965,10 1969,11 1974,12 1975,13 1976,14 1977,15,16 1979,17 1980,18 1982,19,20 1992,21 1997,22 2000,23 2001,24 and 2006.25 In addition, more than 100 national and international organizations have recognized the public health benefits of community water fluoridation.26 Because of its health and economic benefits, CWF has been and is included in the 1990, 2000, and 2010 national health objectives (e.g., Healthy People 2010). Between 1992 and 2002, the proportion of the US population served by CWF increased from 62% to 67%. The Healthy People 2010 CWF objective [21–9] is to increase to 75% the proportion of the US population served by community water systems with optimally fluoridated water.27 More Americans have access to fluoridated drinking water than ever before; in 2006, it was estimated that 184 million or 69% of those served by public water supplies and 61.5% of the US population overall had access to optimally fluoridated water.28 More than 405 million people in more than 60 countries worldwide enjoy the benefits of fluoridated water.29 Community water fluoridation has been hailed as one of 10 great public health achievements of the 20th century.30 Because many communities have not yet adopted fluoridation, the US Centers for Disease Control and Prevention (CDC) has set as a priority the evaluation of the effectiveness of laws, policies, and incentives related to water fluoridation and other public health measures designed to promote and sustain health for all residents across diverse community settings.31 However, opposition to this well-supported public health program continues to frustrate efforts by communities to begin or to continue fluoridation.2

Safety of CWF The scientific evidence base continues to support CWF as a safe and effective public health measure. Reviews of the scientific literature on the health effects of fluoride in the last 18 years have been conducted by the National Health and Medical Research Council, Australian Government (2007)32; National Research Council (NRC), USA (1993, 2006)33,34; World Health Organization (1994, 1996, 2006)35–37; US Agency for Toxic Substances and Disease Registry (2003)38; International Programme on Chemical Safety; WHO (2002)39; Forum on Fluoridation, Ireland (2002)40; Medical Research Council, UK (2002)41; University of York, UK (2000)42,43; Institute of Medicine, USA (1999)44; Health Canada (1999)45; Lewis and Banting, Canada (1994)46; US Public Health Service (1991)47; and Kaminsky et al., New York State Department of Health (1990).48 In addition, the environmental impact of CWF has been reviewed.49,50 All of these reviews have found CWF to be safe and effective. Opponents have claimed potential toxicity from fluoridated water, but none of these claims has been supported by studies of scientific merit.2,51 Water safety is defined and determined by federal, state, and local regulations. The main federal law that ensures the quality of US drinking water is the Safe Drinking Water Act (SDWA). Under SDWA, the US Environmental Protection Agency (EPA) sets standards for drinking water quality and oversees the states, localities, and water suppliers who implement those standards. The current maximum contaminant level goal (MCLG) for fluoride in water is set at 4.0 mg/L,52 well above the optimal levels (0.7 mg/L F–1.2 mg/L F) currently recommended for CWF in the United States for the prevention of tooth decay.53 It has recently been recommended by a committee of the NRC that the MCLG of 4 mg/L for naturally occurring fluoride in water should be lowered to protect against the development of severe enamel fluorosis. The majority of the NRC committee concluded that the MCLG of 4 mg/L is not likely to be protective against bone fractures. Although the NRC committee concluded that the secondary maximum contaminant level of 2 mg/L adequately protects the public from the most severe stage of enamel fluorosis (enamel pitting), there were few studies to assess bone fracture risk in populations exposed to fluoride at the same level in drinking water. However, there was evidence that none of these concerns exist at the optimal levels of fluoride for the prevention of tooth decay.34 Fluorosilicic acid (FSA) is commonly used to fluoridate water. The majority of FSA samples have no impurities, and there is no credible evidence that the use of FSA is of concern.49,54,55

Legality of CWF During the last 60 years, the legality of fluoridation in the United States has been thoroughly tested in our court systems.56 Fluoridation is viewed by the courts as a proper means of furthering public health and welfare.57 No court of last resort has ever rendered an opinion against fluoridation. The highest courts of more than a dozen states have confirmed the constitutionality of fluoridation.58 In 1984, the Illinois Supreme Court upheld the constitutionality of the state’s mandatory fluoridation law, culminating 16 years of court action at a variety of judicial levels.59 Moreover, the US Supreme Court has denied review of fluoridation cases 13 times, citing that no substantial federal or constitutional questions were involved.58 It has been the position of the US courts that a significant government interest in the health and welfare of the public generally overrides individual objections to public health regulation.1 Consequently, the courts have rejected the contention that fluoridation ordinances are a deprivation of religious or individual freedoms guaranteed under the Constitution.58,60 In reviewing the legal aspects of fluoridation, the courts have dealt with this concern by ruling that (1) fluoride is a nutrient, not a medication, and is present naturally in the environment; (2) no one is forced to drink fluoridated water because alternative sources are available; and (3) when a person believes that fluoridation interferes with religious beliefs, there is a difference between the freedom to believe, which is absolute, and the freedom to practice beliefs, which may be restricted in the public’s interest.61,62 Courts have consistently ruled that water fluoridation is not a form of compulsory mass medication or socialized medicine.58,61 Recent legal decisions have upheld CWF, including the use of FSA, that there is no fundamental constitutional right to fluoride-free water, and that the use of fluoride is not forced medication.63–66

Continued Benefit and Need for Fluoridation There is a continued need for CWF to maintain and enhance the reduced prevalence and severity of dental caries. Dental caries remains the most prevalent chronic disease of childhood, with 28% of children aged 2 to 5 years affected by tooth decay. The incidence of dental caries is experienced by 6 of 10 adolescents (12–19 years) and more than 90% of adults (20–64 years).67 The prevalence and severity of dental caries has decreased significantly in the United States as a result of CWF and the nearly ubiquitous use of fluoride toothpaste. The US Task Force on Community Preventive Services strongly recommended CWF for the prevention of dental caries.68 The review that included 21 studies, considered good to fair quality, found a median decrease in dental caries of 29.1% (before-and-after measures) and 50.7% (after measures only) for children aged 4 to 17 years, with varying levels of baseline caries and socioeconomic status. The task force found the evidence of effectiveness was strong. Overall, the prevalence of dental caries among children aged 12 to 17 years declined from 90% in 1971 to 1974 to 67% in 1988 to 1991, and the mean number of teeth that were decayed, missing, or filled (DMFT) as a result of caries declined from 6.2 to 2.8 during this period. More recent data have been aggregated into different age groups of adolescents; for 12 to 19 year olds, the mean DMFT declined from 3.1 in 1988 to 1994 to 2.55 in 1999 to 2004. For 20 to 64 year-old adults, there continues to be a decline in the number of DMFT, from a mean of 12.5 in 1988 to 1994 to 10.3 in 1999 to 2004.67

Additional Considerations Diffusion/Halo Effect There is a benefit from the diffusion of fluoride from fluoridated communities to surrounding nonfluoridated communities via the export of bottled beverages and processed foods.69 This diffusion effect, also referred to as the halo effect, as well as additional sources of fluoride, have reduced the absolute and proportional benefit of water fluoridation, as measured between fluoridated and nonfluoridated communities, from approximately 60% in the 1950 to 1970 era to 18% to 40% since the 1980s. Based on 1986 to 1987 data,70 in regions where 75% of public water supplies are fluoridated, the benefit may not be apparent when measuring caries experience between fluoridated and nonfluoridated communities because of the halo or diffusion effect.71 However, in the Pacific region of the United States where less than 20% of public water supplies were fluoridated, there was a 60% difference in tooth decay experience between fluoridated and non-fluoridated communities.71 Continued CWF programs are essential to maintaining this improved oral health status.

Benefit for Adults CWF benefits everyone in the community, including adults and seniors as well as children. The combined results of 9 studies (7853 participants) examining the effectiveness of water fluoridation in preventing tooth decay in adults were found to be significant at p < .001.72 Adults have more tooth and root surfaces at risk for tooth decay than children. The incidence of dental caries for adults equals or exceeds that of children.73,74 Griffin et al. summarized the need for placing increased attention on the prevention of tooth decay in adults72: Although adults are as likely to experience new caries as children, certain segments of the US adult population—those with low incomes and the elderly—may have little or no access to restorative or preventive clinical care. At present, approximately 15% of state Medicaid programs provide no adult dental benefits at all, and approximately 45% cover only tooth extraction and emergency services (Oral Health America, 2003). Routine dental care is one of the few health areas not covered by Medicare. Limited access to restorative care increases the need for effective prevention; complications and pain and suffering are more likely if caries remain untreated. The proportion of the US population comprised of older adults is increasing, most of these persons are likely to be dentate and at risk for dental caries, and many lower-income adults lack access to timely restorative care. Our finding that fluoride is effective among all adults supports the development and implementation of fluoride programs to serve this population.72, p 414-5

Cost-Effectiveness Fluoridation is a highly cost-effective means of preventing tooth decay in the United States, regardless of socioeconomic status.75–77 The cost of CWF can vary in each community depending on several factors: size of the community (population and water usage); number of fluoride injection points where fluoride will be added to the water system; amount and type of equipment used to add and monitor fluoride levels; amount and type of fluoride compound used, its price, and its costs of transportation and storage; and expertise of personnel at the water plant.78 The annual cost for a US community to fluoridate its water is estimated to range from approximately $3.00 per person in small communities to approximately $0.50 per person in large communities.76

Cost Savings of CWF For communities of more than 20,000 people where it costs approximately $0.50 per person per year to fluoridate the water, every $1.00 (1995) invested in this preventive measure yields approximately $38 savings in dental treatment costs.79 At least 60% of the US population on public water systems has received fluoridated water since 1990, translating to savings in dental treatment costs of more than $25.7 billion between 1990 and 2000.80 In analyzing annual per person cost savings resulting from fluoridation, Griffin, Jones, and Tomar found a range from $16 in very small communities to $19 in large communities.76 These authors concluded, “On the basis of the most current data available on the effectiveness and cost of fluoridation, caries increment, and the cost and longevity of dental restorations, we find that water fluoridation offers significant cost savings.”76, p78 The annual incremental mean benefit of fluoridation has been found to be 0.19 tooth surfaces (range 0.04 to 0.34). This equates to a mean of 1.9 tooth surfaces every decade, or 9.5 tooth surfaces over 50 years.76 Preventing 10 tooth surfaces from decay translates into preventing the need for 10 fillings or perhaps two molars from needing crowns (a molar has five tooth surfaces). The tooth surface index (DMFS) does not address the severity of decay in any one surface or the need for treatment, which could vary from a small filling to a root canal treatment and crown or an extraction.

Disparities Because of the multifactorial nature of tooth decay, oral health disparities within and between countries are related to sugar consumption, fluoride use, dental care, and social determinants of health.80 However, it has been shown that children with the greatest dental need and who are at highest risk for tooth decay benefit the most from water fluoridation.82–87 Therefore, CWF helps reduce disparities in tooth decay prevalence. This has been most eloquently and succinctly articulated by Burt: “There is no practical alternative to water fluoridation for reducing these disparities in the United States.”88, p195

Pre- and Post-Eruptive Benefits Fluoridation protects teeth in two ways: systemically, when delivered through the water supply to children during the tooth forming years, and topically, through direct contact with teeth throughout life.89 Animal and human studies have demonstrated the topical and systemic benefits of fluoride.90,91 Epidemiological studies using data collected between 1991 and 1995 on children in Australia have confirmed earlier findings that higher pre- than posteruptive fluoride exposure is more beneficial for overall caries experience and for pit and fissure surfaces caries reduction. In those studies, children with optimum exposure to fluoridated water both pre- and posteruption had the lowest caries levels in all surface types and there was an exposure–response relationship between preeruptive exposure and caries.92–94

Total Fluoride Intake and Enamel Fluorosis Enamel fluorosis is a biomarker of fluoride intake during tooth developing years. In a minority of children, fluoride exposure from birth through age 8, when teeth are forming, may result in changes within the outer surface of the tooth called enamel fluorosis. Fluorosis occurs only on primary and permanent teeth while they are forming under the gums; once the teeth come into the mouth, they are no longer able to develop this condition. Clinically, the appearance of enamel fluorosis may vary and is usually bilateral. In its mildest form, it appears as faint white lines or streaks visible only to trained examiners under controlled examination conditions. In its pronounced moderate form, fluorosis manifests as white mottling of the teeth in which noticeable white lines or streaks often have coalesced into larger opaque areas; brown staining of the enamel also may be present. In its most severe form, pitting and actual breakdown of the enamel may occur. The prevalence of severe enamel fluorosis is very low (near zero) at fluoride concentrations in drinking water less than 2 mg/L.95 In recent years, there has been an increase in the prevalence of children seen with nonsevere enamel fluorosis in both optimally fluoridated and nonfluoridated areas of the United States. The greatest relative increase in enamel fluorosis prevalence has occurred in nonfluoridated areas.96 Although US NHANES data from 1999–2002 have shown that 32% of US children aged 6 to 19 years have some enamel fluorosis,97 few survey participants had severe enamel fluorosis and less than 4% had moderate or severe enamel fluorosis. Although professional interest in limiting the amount of fluoride toothpaste delivered to young children and supervising their toothbrushing was expressed in the 1980s as a means of reducing the risk for enamel fluorosis, only during the early 1990s was this approach adopted broadly as a public health measure, which was too late to alter the risk for fluorosis among the 12 to 19 year age cohort in NHANES 1999–2002.97 Although it has been estimated that only approximately 2% of US schoolchildren may experience perceived esthetic problems related to enamel fluorosis that could be attributed to the currently recommended levels of fluoride in drinking water,98 in more recent studies, it has been found that mild fluorosis does not have a negative association on the perception of dental appearance.99 Children and their parents who had mild fluorosis were even better off in perception of oral health when other factors were controlled for in multivariate models. This rather unexpected finding, the authors suggest, might be explained by the fact that better oral health was often perceived as being without caries.99 Various studies in Canada, Australia, and the United States have shown a relationship between young children swallowing too much fluoride from fluoride toothpaste and subsequent enamel fluorosis development.96,100,101 In a study of 10- to 14-year-old children in Massachusetts and Connecticut, Pendrys found that enamel fluorosis in the optimally fluoridated study sample was attributed to early toothbrushing behaviors, inappropriate fluoride supplementation, and the use of infant formula in the form of a powdered concentrate.96 Enamel fluorosis in the nonfluoridated study sample was attributed to fluoride supplementation under the pre-1994 protocol and early toothbrushing behaviors. In the nonfluoridated study sample, 65% of the enamel fluorosis cases were attributed to fluoride supplementation under the pre-1994 protocol. An additional 34% was explained by the children swallowing fluoride toothpaste when they brushed more than once per day during the first 2 years of life. In the optimally fluoridated study sample, 68% of the enamel fluorosis cases were explained by the children using more than a pea-sized amount of toothpaste during the first year of life, 13% by having been inappropriately given a fluoride supplement, and 9% by the use of infant formula in the form of a powdered concentrate. Recommendations have been made to reduce the occurrence of enamel fluorosis by controlling identified risk factors.78

Fluoride Intake From Foods and Beverages Water and water-based beverages are the chief source of dietary fluoride intake. Conventional estimates are that approximately 65% to 75% of dietary fluoride comes from water and water-based beverages.102 In 1997, the Food and Nutrition Board of the Institute of Medicine developed a comprehensive set of reference values for dietary nutrient intakes.44 The adequate intake (AI) establishes a goal for intake to sustain a desired indicator of health without causing side effects. In the case of fluoride, the AI is the daily intake level required to reduce dental decay without causing moderate enamel fluorosis. The AI for fluoride from all sources (fluoridated water, food, beverages, fluoride-containing dental products and dietary fluoride supplements) is set at 0.05 mg/kg/day.44 Using the established AI of 0.05 mg/kg, the amount of fluoride for optimal health to be consumed each day has been calculated by gender and age group (expressed as average weight).103 The tolerable upper intake levels (UL) are higher than the AI and are not the recommended level of intake. The UL is the estimated maximum intake level that should not produce unwanted effects on health. The UL for fluoride from all sources (fluoridated water, food, beverages, fluoride-containing dental products and dietary fluoride supplements) is set at 0.10 mg/kg/day for infants, toddlers, and children through 8 years of age. For older children and adults, who are no longer at risk for enamel fluorosis, the UL for fluoride is set at 10 mg/day, regardless of weight.44 Dietary fluoride intakes by adults from food, water, and beverages, where the concentration is 1.0 parts per million (ppm) fluoride in water, range from 1.4 to 3.4 mg/day; where the concentration is less than 0.3 ppm fluoride, the range is from 0.3 to 1.0 mg/day.44 USEPA has set the MCLG for fluoride in drinking water at 4 mg/L; by converting the MCLG of 4.0 mg/L to a mg/kg/day basis using standard water consumption estimates and body weight data from the NHANES III survey, EPA has concluded that dietary exposure to fluoride, including food exposure to sulfuryl fluoride used as an insecticide, uses 35% of the MCLG (expressed as mg/kg/day) for the US population; 23% of the MCLG (expressed as mg/kg/day) for youth 13 to 19 years, 37% of the MCLG (expressed as mg/kg/day) for children 3 to 5 years, 28% of the MCLG (as mg/kg/day) for children 1 to 2 years, and 35% of the MCLG (expressed as mg/kg/day) for all infants younger than 1 year old. These risk estimates are below the USEPA’s level of concern.104

Infant Formula and the Risk for Enamel Fluorosis Although only a small factor in the risk for enamel fluorosis, the American Dental Association (ADA) (and the CDC) has issued guidance for parents and caregivers of infants younger than 12 months of age to consult with their pediatrician, family physician, or dentist on the most appropriate type of water to use to reconstitute infant formula.105 Recent evidence suggests that mixing powdered or liquid infant formula concentrate with fluoridated water on a regular basis for infants primarily fed in this way may increase the chance of a child’s developing the faint white markings of very mild or mild enamel fluorosis. Occasional use of water containing optimal levels of fluoride should not appreciably increase a child’s risk for fluorosis. Studies have not shown that teeth are likely to develop more esthetically noticeable forms of fluorosis, even with regular mixing of formula with fluoridated water.106

CWF and Fluoride Toothpaste Because frequent exposure to small amounts of fluoride each day will best reduce the risk for dental caries in all age groups, all people are recommended to drink water with an optimal fluoride concentration and to brush their teeth twice daily with fluoride toothpaste.78 Fluoride is the only nonprescription toothpaste additive proven to prevent dental caries.78 Because water fluoridation is not available in many countries, toothpaste might be the most important source of fluoride globally.78 There is an additive benefit of fluoride toothpaste. Combined use of fluoride toothpaste and fluoridated water offers protection greater than either used alone.78 In the United States, the standard concentration of fluoride in fluoride toothpaste is 1,000 to 1,100 ppm. Fluoride toothpaste is helpful to all age groups and should be used at least twice a day. Since 1991, manufacturers of fluoride toothpaste marketed in the United States have, as a requirement for obtaining the ADA Seal of Acceptance, placed instructions on the package label stating that children aged younger than 6 years should use only a pea-sized amount of fluoride toothpaste. This is reported to sharply reduce the role of fluoride toothpaste as a risk factor for enamel fluorosis.107 Toothpaste labeling requirements mandated by FDA in 1996 also direct parents of children aged younger than 2 years to seek advice from a dentist or physician before introducing their child to fluoride toothpaste.108 Children younger than 6 years of age should have parents supervise and apply the toothpaste so as to limit the amount that may be swallowed; fluoride toothpaste should be spit out rather than swallowed. The propensity of young children to swallow toothpaste has led to development of “child-strength” toothpaste with lower fluoride concentrations. Such a product, not currently available in the United States, would be a desirable alternative to currently available products for many young children. Toothpaste containing 500 to 550 ppm fluoride might be almost as efficacious as that containing 1,000 ppm fluoride.109 A British study reported that the prevalence of diffuse enamel opacities (an indicator of mild enamel fluorosis) in the upper incisors was substantially lower among children who used toothpaste containing 550 ppm fluoride than among those who used toothpaste containing 1,050 ppm fluoride.110 An Australian study reported a decrease in the prevalence of enamel fluorosis and no increase in caries after steps were taken to promote use of toothpaste for children containing 400 ppm fluoride and reduce dosages for dietary supplements.111 Adults benefit considerably from CWF and fluoride toothpaste. A review of adult studies after 1980 found that any fluoride, whether self-applied, professionally applied, via water fluoridation, or in combination, averted 0.51 carious coronal and root surfaces per year.72

Fluoridation and Dental Sealants The effectiveness of dental sealants in community-based programs may be further improved when coupled with lifetime exposure to optimally fluoridated water.112

Bottled Water In 2006, the FDA’s Center for Food Safety and Applied Nutrition issued a Health Claim Notification for Fluoridated Water and Reduced Risk of Dental Caries.113 Labels on bottled water with 0.6 to 1.0 mg/L fluoride may claim “Drinking fluoridated water may reduce the risk of [dental caries or tooth decay].” In addition, the health claim is not intended for use on bottled water products specifically marketed for use by infants. Because the use of bottled water has increased and because the majority of commercial bottled water is low in fluoride, there is the potential for an increase in dental caries.114,115 To encourage bottled water manufacturers to provide optimally fluoridated water, the ADA has introduced a certification program for foods and beverages that are beneficial to oral health, including fluoridated bottled water.116 Per capita consumption of bottled water has increased from approximately 190 mL/person/day in 2001 to approximately 285 mL/person/day in 2006.117 Considering water from all sources, EPA surveys in 1994 to 1998 found the mean per capita daily average total water ingestion was 1.233 L.118 In the EPA surveys, 75% was from community water, 13% from bottled water, 10% from other sources (e.g., well, spring, and cistern), and 2% from unidentified sources. Assuming no general increase in overall water consumption, bottled water use has increased from 15% in 2001 to 23% in 2006 as a proportion of total water consumption. ADA recommends that dentists ask their patients about bottled water use and advise them about the possible removal of fluoride by some home water treatment systems.118 Further, ADA and CDC recommend labeling of bottled water with the fluoride concentration of the product.78,119

Salt Fluoridation Salt fluoridation is practiced as a community-based alternative to water fluoridation in many countries where there are few central water systems, water infrastructure is otherwise not appropriate, or where other factors preclude the use of water fluoridation. It has been estimated that 40 million people use salt fluoridation, mainly in European, South American, and Central American countries.120 A concentration of 200 to 250 mg fluoride per kg salt is typically used in fluoridated salt. It is recommended that a national fluoride program use only one of these approaches.121

Fluoride Supplements Where community water fluoridation is not feasible because there is no central water supply or because there are a large number of wells and a small population, school-based fluoride supplement programs are an alternative for communities with suboptimal fluoride in drinking water.122 Prescription fluoride supplements (of 0.25 mg/day, 0.5 mg/day, or 1 mg/day, depending on the age of the child and the concentration of fluoride in the water supply—whether less than 0.3 mg/L or between 0.3 and 0.6 mg/L, and all sources of fluoride) are currently recommended daily for children between 6 months of age and 16 years where the fluoride concentration of the water supply is less than 0.6 mg/L (ppm).78 Currently, in addition to age and fluoride concentration of drinking water, all sources of fluoride should be evaluated with a thorough fluoride history when physicians or dentists prescribe fluoride supplements. Patient exposure to multiple water sources can make proper prescribing complex.123 Home compliance with use of fluoride supplements can be challenging. Health care providers must educate parents, or school personnel in the case of school-based programs, about the appropriate use of the fluoride supplements; moreover, parents and recipients must understand the importance of fluoride supplements, the recommended dose, and the need for compliance on a daily basis for many years. Concomitantly, fluoride supplements are not always prescribed as recommended; studies have found more than one third of children receive prescriptions with incorrect dosage or do not receive prescriptions.124,125 Long-term compliance with daily fluoride supplements has been reported as poor.126,127 As a public health measure, because of poor compliance by individual providers and patients in the private sector, fluoride supplements are less effective than water fluoridation for providing caries prevention. Because inappropriate prescribing of fluoride supplements in fluoridated communities and high doses of fluoride supplements have been found to contribute to enamel fluorosis, alternative doses and schedules have been proposed and are being used in other countries.128

Comparative Costs of Community-Based Tooth Decay Prevention Programs The costs of school-based fluoride supplement programs have been compared with the cost of CWF, noting that school-based programs affect children only, whereas CWF benefits all age groups of children and adults. The cost to achieve the same level of benefit of prevention of tooth decay was three times higher for fluoride supplements provided in a school-based program compared with water fluoridation for all residents.129 The largest US study conducted to determine the cost and effectiveness of various tooth decay prevention strategies for schoolchildren was conducted between 1977 and 1982. The National Preventive Dentistry Demonstration Program found that dental health lessons, brushing and flossing, fluoride tablets and mouthrinsing, and professionally applied topical fluorides were not effective in reducing a substantial amount of dental decay, even when all of these procedures were used together. Occlusal sealants prevented 1 to 2 carious surfaces in 4 years. Children who were especially susceptible to decay did not benefit appreciably more from any of the preventive measures than did children in general. However, CWF was reaffirmed as the most cost-effective means of reducing tooth decay in children. By contrast to the $23 per year cost of maintaining a child in a sealant program, the annual per capita cost (in 1981 dollars) of water fluoridation in 5 US communities ranged from $0.06 in Denver, Colorado, to $0.80 in rural West Virginia.73

Topical Fluorides Because of the adoption of water fluoridation and widespread use of fluoride toothpaste, approximately 75% of the US public is at low risk for dental caries. Therefore, the use of any professionally applied fluoride, including fluoride varnish, should be limited to those individuals and communities deemed to be at moderate to high risk for developing dental caries.130 A targeted approach offers additional opportunities toward improving the prevention and control of dental caries.130 The use of fluoride varnish to prevent and control dental caries in young children and seniors is expanding in both public and private dental practice settings and in nondental settings that incorporate health risk assessments and counseling. These settings include Head Start programs and Special Supplemental Nutrition Programs for Women, Infants, and Children; medical offices; well-child clinics and home visits conducted by public health nurses; child care programs; and other, sometimes overlapping, community programs.

Public Information on CWF Public opinion polls have consistently shown 70% or more of the adult US population supports fluoridation.131 Several organizations provide detailed information on CWF on Web sites, including the CDC132 and ADA.133 The ADA periodically updates Fluoridation Facts, a review of fluoridation literature in question and answer format.134 In addition, ADA has a resource list of materials.135 However, a review of Web sites providing information on CWF revealed that, of 59 sites meeting specific criteria from a list of the first 100 Web sites found when searching “water fluoridation” using the Google search engine (www.google.com) on February 15, 2003, 54% recommend water fluoridation compared with 31% that oppose it.136 Armfield analyzed Web information on fluoridation from Australia in 2006 using 5 search engines—Google, Yahoo, MSN, AOL, and Ask—and found that of the first 20 results from each Web site, searching for “water fluoridation,” 29 of the sites were for fluoridation, 55 were against it, with 9 reviews and 7 others.2 Armfield stated, “Although the overwhelming majority of scientific enquiry supports the benefits of water fluoridation, members of the public who type the term ‘water fluoridation’ into any of the major search engines would immediately be presented with a disproportionate percentage of anti-fluoridation websites.”2, p3 Thus, there may be an increasing number of Web sites providing information that is in opposition to established public health policy on water fluoridation. Water fluoridation opponents are said to use multiple techniques to undermine the scientifically established effectiveness and safety of water fluoridation. The materials they use are often based on Internet resources or published books that present a highly misleading picture of water fluoridation. Despite an extensive body of literature, both studies and results within studies are often selectively reported, giving a biased portrayal of water fluoridation effectiveness. Positive findings are downplayed or trivialized, and the population implications of these findings misinterpreted. Ecological comparisons are sometimes used to support spurious conclusions. Opponents of water fluoridation frequently repeat that water fluoridation is associated with adverse health effects and studies are selectively picked from the extensive literature to convey only claimed adverse findings related to water fluoridation.2

Ethics of CWF Several reviews have considered the ethics of CWF.137–140 The reviews rely on the preponderance of scientific evidence of benefit and lack of harm and have concluded that CWF is ethical, in part, because it leads to the reduction of health inequalities and the reduction of ill health, particularly among vulnerable groups, and provides an economic benefit to both society and to individuals. With water fluoridation, a whole area either receives fluoridated water or does not. Populations do not remain static, as people move to and from an area. In practical terms, it would therefore not be feasible to seek individual consent. The most appropriate way of deciding whether fluoride should be added to water supplies is to rely on democratic decisionmaking procedures, with public input informing those empowered by the public to make such public health decisions (e.g., local health board, city council, water board, or state legislature). These procedures should be implemented at the local and regional, rather than national, levels because the need for and perception of water fluoridation varies in different areas.138 Account should be taken of relevant evidence and of alternative ways of achieving the intended benefit in the area concerned. Whatever policy is adopted, dental health and any adverse effects of fluoridation should be monitored. The Nuffield Council found there is a need for better and more balanced information for the public and policymakers.138 From an ethical perspective, fluoridating water supplies can be seen as replicating the benefits already conferred on those communities receiving water naturally containing 1 part per million of fluoride. Moreover, the greatest benefit of all goes to that section of the population least able to help themselves—children. Drinking fluoride-free water is not a basic human right but a question of individual preference. In a society where people come together for mutual benefit, it is a question of balancing such personal preferences against the common good arising from less disease, less pain, less suffering, and better health that fluoridation brings.139

Summary Dental caries (tooth decay) continues to be the most common chronic disease of childhood, and dental caries incidence for adults exceeds that of children. Although there are gross oral health disparities for minorities, eliminating health disparities is an overarching priority area for APHA. Community water fluoridation has been shown to be the most cost-effective public health measure for the primary prevention of dental caries and has been shown to be the most effective public health strategy to reduce disparities in dental caries between ethnic and racial groups. Yet, the US public is generally uninformed about the appropriate use of fluoride and community water fluoridation, and information available to the public on community water fluoridation is not always evidence based.

Therefore be it resolved that APHA—

• Reiterates its strong endorsement and recommendation for the fluoridation of all community water systems as a safe and effective public health measure for the prevention of tooth decay; • Recommends that federal, state, and local agencies and organizations in the United States promote water fluoridation as the foundation for better oral health; • Recommends promotion and increased support by federal, state, and local entities for adequate public health infrastructure to ensure safe and effective water fluoridation practices, including monitoring, training, technical and financial assistance, and promotion to expand and maintain water fluoridation programs; • Recommends increased support by federal agencies for continued research on the safety and effectiveness of water fluoridation and other measures to deliver fluoride to communities and individuals, including effective programs and long-term outcomes; • Supports efforts to educate public health and other health professionals, decisionmakers, and the public on community water fluoridation and other appropriate uses of fluoride in the prevention of tooth decay; • Recommends that bottled water manufacturers offer an option of bottled water with an optimal level of fluoride, all bottled water be labeled with its fluoride concentration, and APHA collaborate with other professional groups to promote this recommendation; • Recommends that the FDA consider all US and non-US evidence-based studies concerning low-concentration fluoride toothpaste for children under age 6 during tooth developing years to reduce the risk of enamel fluorosis and tooth decay; and • Should collaborate with other professional groups to encourage the National Institutes of Health to study the efficacy and safety of low fluoride toothpastes.

Sure thing...to tell you the truth...I just want clean drinking water...I'll blame myself and being part British for my bad teet. Thanks

Just thought the article was interesting and figured I'd give pro flourides some love.

I don't take too much stock in reports from folks whose job it is...but it's tough to find anything impartial nowadays.

Hi J

 

Yeah, Tim and I are just sitting here having a conversation, asking when does one know what to trust. I'm really struggling with this, on many issues. I've read and watched so many documentaries about cover-ups, conspiracies (that were later found to be true).. I've seen peer reviewed "scientific" research dismantled due to industry bias, we are told products are safe and later discover they kill...... well,  now I tend to lean toward worst case (conspiracy) scenario, when it's not necessarily warranted.

and then there is shit like this:

 

 

Burke worked for the Cancer Institute for over 30 years. He's a biochemist who did a study of cancer rates of 10 cities with water fluoridation and 10 cities without it.

 

ALSO:

 

2012 Harvard study links fluoridation to brain damage and lower IQ http://www.hsph.harv...grandjean-choi/

 

"The average loss in IQ was reported as a standardized weighted mean difference of 0.45, which would be approximately equivalent to seven IQ points for commonly used IQ scores with a standard deviation of 15.*  Some studies suggested that even slightly increased fluoride exposure could be toxic to the brain. Thus, children in high-fluoride areas had significantly lower IQ scores than those who lived in low-fluoride areas. The children studied were up to 14 years of age, but the investigators speculate that any toxic effect on brain development may have happened earlier, and that the brain may not be fully capable of compensating for the toxicity.

“Fluoride seems to fit in with lead, mercury, and other poisons that cause chemical brain drain,” Grandjean says. “The effect of each toxicant may seem small, but the combined damage on a population scale can be serious, especially because the brain power of the next generation is crucial to all of us.”

 

 

 

Yeah, I'll pass

Flouride....no thanks.  Eeek

 

Chlorine....whatever.  The bad part of the Chlorine evaporates so fast that all you'd have to do is sit your water out for 24 hours before drinking it and you have barely anything to worry about.  But Flouride?  Yea, do some research on it.  It's nasty nasty stuff.

 

I like my mountain well water.  Plus I live near Saratoga Springs where we have some of the yummiest water just popping out of ground.  :)

and some of the smelliest/nastiest as well...(recalling a late SPAC ext parched and slamming down some of the serious mineral stuff)

 

I now live in a town w/out fluoride.  I use fluoride as a rinse only, but never feared it when we lived in fluorideland.  What's 7 IQ points in the grand scheme of things (pretty sure I've had worse over my lifetime)
