From the Past Toward the Year 2000

Community water fluoridation is the deliberate upward adjustment of the natural trace element fluoride to promote public health through the prevention of dental caries (tooth decay) in accordance with scientific and dental guidelines. Fluoride is present naturally in variable amounts in all soils and existing water supplies. It is also present in animal and plant food consumed by people. The highest concentrations in mammals are found in the bones and teeth.
