The U.S. Public Health Service’s recommendation is a fluoride concentration of 0.7 mg/L of drinking water—and there were not enough data to determine if 0.7 mg/L of fluoride exposure in ...
Some pro-fluoride organizations, including the ADA, argue that the final version still falls short of providing conclusive evidence and should not lead to policy changes around water treatment.
Water fluoridation is the controlled addition of fluoride to public water supplies to reduce tooth decay. Fluoridated water maintains fluoride levels effective for cavity prevention, achieved naturally or through supplementation. [2] In the mouth, fluoride slows tooth enamel demineralization and enhances remineralization in early-stage cavities ...
The CDC calls the practice of adding fluoride to tap water systems one of the 10 greatest public health achievements of the last century.
Upon treatment with a standard acid, fluoride salts convert to hydrogen fluoride and metal salts. With strong acids, it can be doubly protonated to give H 2 F +. Oxidation of fluoride gives fluorine. Solutions of inorganic fluorides in water contain F − and bifluoride HF − 2. [21]
The research had two goals: (1) to warn communities with a high concentration of fluoride of the danger, initiating a reduction of the fluoride levels in order to reduce incidence rates of fluorosis, and (2) to encourage communities with a low concentration of fluoride in drinking water to add fluoride in order to help prevent tooth decay.
