Fluoride and the Thyroid: The Controversy

Water fluoridation is defined as the addition of industrial-grade fluoride chemicals — typically hydrofluorosilicic acid or and sodium silicofluoride — to the water supply, with the goal of helping prevent tooth decay. It’s estimated that 70% of the water supply in the United States is fluoridated. This contrasts with most developed nations, including all of Japan and most of western Europe, which do not have fluoridation programs.

The fluoridation of local water supplies in the United States has become an increasingly contentious public issue in some areas, with vigorous debates taking place in communities that are considering fluoridation, and in some cases, activists attempting to overturn existing fluoridation programs.
