Fluoridated Drinking Water

Nearly all naturally occurring water sources contain fluoride. Fluoride is a compound that contains an ionic form of the element fluorine. Fluoride is added in the treatment process by many public water systems. The U.S. government sets optimal fluoridation at 0.7mg/L and a safety standard at 2.0 mg/L. Fluoridation in this range has been beneficial in reducing tooth decay. Water fluoridation prevents tooth decay mainly by providing teeth with frequent contact with low levels of fluoride throughout each day and throughout life. The American Dental Association endorses fluoridation of community water supplies as safe and effective for preventing tooth decay. This support has been the Association's position since 1950.
