About Fluoridation and the AFS

Fluoride exists in water naturally. The public health initiative of water fluoridation is simply the adjustment of that fluoride to the level at which maximum dental decay benefit will be obtained with no adverse effects.

Here you will find evidence based information on fluoride and all aspects of water fluoridation including: water fluoridation and infant formula, support for water fluoridation, cost and cost effectiveness of water fluoridation, water fluoridation and the environment, the dental benefits of water fluoridation, the effects on general health, dental health, health inequalities, and dental fluorosis.


For Further Information on the aims of the society, and our main activities please visit the About Us section.

The American Fluoridation Society was founded in 2014 by a group of concerned professionals anxious to see all residents of the United States served by community water systems enjoy the benefits of community water fluoridation (CWF). Equally important to this society is to prevent rollback attempts by opponents of CWF, as well as to initiate CWF where it has not been previously available.

EPA Denies Latest Petition from Fluoridation Opponents

Steven D. Slott, DDS
Communications Officer
American Fluoridation Society

Feb 22, 2017…Pursuant to its 90 day requirement to respond to consumer petitions, the EPA today formally denied a petition filed by fluoridation opponents in November, 2016. The petition submitted on behalf of the activist groups Fluoride Action Network, Food & Water Watch, Organic Consumers Association, the American Academy of Environmental Medicine, the International Academy of Oral Medicine and Toxicology, Mom’s Against Fluoridation, and various individuals, sought to go around the Safe Water Drinking Act under which fluoride and other contents of drinking water are regulated by the EPA, and appeal instead for a ruling under the Toxic Substances Control Act. The petition sought to “prohibit the purposeful addition of fluoridation chemicals to U.S. water supplies.”, using as its central argument, a belief of neurotoxicity as the “risk” of fluoridated water. In addition to the written petition, the petitioners also provided an “in-person” oral argument to the EPA on January, 30, 2017.

As stated in an unofficial 40 page pre-publication response, the EPA cited its reason for denial as “primarily because EPA concluded that the petition has not set forth a scientifically defensible basis to conclude that any persons have suffered neurotoxic harm as a result of exposure to fluoride in the U.S. through the purposeful addition of fluoridation chemicals to drinking water or otherwise from fluoride exposure in the U.S.” The document then went on to systematically explain the flaws and/or irrelevance of the human, animal, and cell studies cited by the petitioners as their support, the misrepresentations of findings of these studies by petitioners, and the lack of the substantive evidence required for such a petition to be favorably considered.

In discussing other claims of the petition, the EPA rebuffed the petitioners contention that fluoridation has no benefit, citing facts and figures of the incidence of dental decay in the U.S., and the devastating effects of untreated dental decay. It went on to provide a detailed explanation of the topical and systemic mechanism of dental decay prevention by fluoride and the health benefits of “having fewer cavities, less severe cavities, less need for fillings and removing teeth, and less pain and suffering due to tooth decay.”
