Fluoride does not prevent tooth decay. According to numerous studies, water fluoridation actually increases tooth decay. The AMA and others fallaciously claim that fluoride added to over 62% of U.S. water supplies reduces tooth decay. However, no less than six studies from dental journals show it does not and, in fact, may increase the likelihood of dental cavities.
Exposure to fluoride often results in dental fluorosis. Large numbers of U.S. young people — estimated up to 80 percent in some cities — now have dental fluorosis, the first visible sign of excessive fluoride exposure. Dental fluorosis consists of damage to tooth-forming cells, leading to a defect in tooth enamel. It is also an indicator of fluoride damage to bones.
