Consumption of Fluoridated Water Has Been Linked to Reduced IQ in Children

A recently published Harvard University study found that children living in communities with high concentrations of fluoride in their water had IQ scores that were on average 7 points lower than those living in communities with low fluoride concentrations (Choi, Sun, Zhang & Grandjean, 2012)


This study was reinforced by the even more recent 2015 pilot study published in the Journal of Neurotoxicology and Teratology which showed that "fluoride in drinking water may produce developmental neurotoxicity" (Anna L. Choi, Guifan Sun, Ying Zhang & Philippe Grandjean, 2012).


A study by Ding and colleagues published in The Journal of Hazardous Materials in 2011 also found that consuming water with low concentrations of fluoride was associated with reductions in IQ. They established a dose-response relationship such that a 1mg/L increase in fluoride found in urine was associated with a 0.59 decrease in IQ. “In conclusion, our study suggested that low levels of fluoride exposure in drinking water had negative effects on children’s intelligence and dental health and confirmed the dose-response relationships between urine fluoride and IQ scores as well as dental fluorosis.” (Ding, et al., 2011).



Consumption of Fluoridated Water Has Been Associated With an Increased Risk of Osteosarcoma, a Form of Bone Cancer

A study by Bassin (2006) found that boys aged 6-8 who were exposed to fluoridated water had 5-7 times increased the risk of developing osteosarcoma during adolescence. Several other studies conducted by the National Cancer Institute and New Jersey Department of Health also found a link between fluoride and osteosarcoma in young males (Cohn, 1992; NCI, 1990).



There is No Evidence that Drinking Artificially Fluoridated Water Prevents Dental Decay

The largest study of tooth decay in the United States found that there was no significant difference in dental decay between those living in fluoridated and non-fluoridated communities (Brunelle & Carlos, 1990). Other research also shows that there is NO relationship between dental decay and the amount of fluoride ingested (Warren et al., 2009).


In the Year 2000, the Environmental Protection Agency Had Not Researched the Health or Behavioral Effects of Fluoride

In 2000 the chief of the EPA's Treatment Technology Evaluation Branch of the Water Supply and Water Resources Division admitted that they have not researched the health or behavioural effects of drinking hydrofluorosilicic acid.



By 2009, The EPA lists Fluoride as having “Substantial Evidence of Developmental Neurotoxicity”

A review of human and animal studies conducted by the EPA in 2009 listed fluoride as a chemical for which there is substantial evidence of developmental neurotoxicity. Chemicals like formaldehyde, DDT and Glufosinate Ammonia are listed as “Minimal Evidence of Developmental Neurotoxicity”.



Most Developed Countries do Not Fluoridate Their Public Water Supplies

While the United States considers water fluoridation a public health achievement, most other developed countries have rejected water fluoridation altogether. Most countries do not fluoridate their water and 97% of the population in Western Europe has access to water without any added fluoride.



Countries that Fluoridate do Not Have Less Tooth Decay

It is commonly believed that the reason for the decline in tooth decay in the United States over the past 60 years is water fluoridation, however, the same trend can be seen in other developed countries throughout the world who do not fluoridate their public water supplies.



Fluoride is the Only Medicine that gets Added to the Water Supply

Fluoride has the distinction of being the only chemical added to the water supply that does not treat the water. For example, chlorine is added to water, but this is due to its ability to kill bacteria. Fluoride is added to water to medicate people to “fight tooth decay.”



Fluoridation is an Unnatural Process

Many advocates of fluoridation say “nature thought of fluoridation first.” By this, they are saying that fluoride is a “naturally occurring element” found in most water supplies and we are simply “adjusting the amount found in water to the optimal level for human health”.  Unfortunately, the type of fluoride found in most water supplies is hydrofluosilicic acid and is a waste byproduct of phosphate and aluminum production plants which is “scrubbed” from smokestacks and collected in waste pits. There is nothing natural about fluoride.



41% of American Teens Aged 12-15 Show Signs of Overexposure to Fluoride

A national survey by the CDC from 1999-2004 shows that 41 percent of American teens aged 12-15 have a condition known as dental fluorosis or mottling of the teeth. This is a defect of the tooth enamel caused by too much exposure to fluoride. If the teeth are “windows to the bones” then what do these children’s bones look like?



There are Only Risks for Infants Consuming Fluoridated Water

Well into the 1990s, health officials in the US and Canada believed that parents should give fluoride to infants. This has changed with the Institute of Medicine recommends that infants only consume a small amount of fluoride, no more than 0.5 mg/day from all sources. The CDC also provides an outline on the safety of children consuming fluoride however never bothers to mention exactly how much fluoride is safe instead downplaying the risks by stating “if your child is exclusively consuming infant formula reconstituted with fluoridated water, there may be an increased chance for mild dental fluorosis.”
