The Concerns Associated with the Addition of Fluoride to Drinking Water . People with poor kidney function should avoid fluoridated water because of their limited ability to excrete Fluoride
Baby formula made with fluoridated water is no longer considered safe – American Dental Association, Nov 2006
The most recognized problem with the ingestion of too much fluoride is dental fluorosis. This condition is characterized by the failure of tooth enamel to crystallize properly in permanent teeth. The effects range from chalky, opaque blotching of teeth to severe, rust-colored stains, surface pitting and tooth brittleness.
This condition, though worrisome, may not be the key concern, at least according to some researchers. Dr. Phyllis Mullenix believes, based on her research, that fluoride acts in a way that lowers the I.Q. of children (“Neurotoxicity of Sodium Fluoride in Rats”, Mullenix, P. Neurotoxicology and Teratology, 17 (2), 1995).
Dr. William Marcus, believes that a study conducted by Battelle for the National Toxicology Program on the toxicology of fluoride shows that there were dose-related increases in bone cancer in male rats. Dr. Marcus also questions the removal by peer reviewers of cancers at other sites in the rats as well. Especially worrisome to Dr. Marcus is the fact that levels of fluoride that caused the cancers in the rats were lower than those seen in humans who ingested lower amounts, but for a longer period. These levels are generated because fluoride is accumulated in the body and is not easily secreted.

An article in the Irish Times of Dublin on August 16, 1999, reports that Dr. Hans Moolenburgh’s research in Holland found that up to 4 percent of people using fluoridated water experienced health problems. These problems ranged from gastrointestinal disorders to mouth sores to rashes to headaches to forms of arthritis to more serious concerns such as cancers and neurological complaints.
