Fluoride is added to municipal water supplies to promote healthy teeth formation.
<h3>What are the functions of fluoride?</h3>
Fluoride is an inorganic, monatomic anion of fluorine, with the chemical formula F⁻ , whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless.
Fluoride is a mineral that occurs naturally and is released from rocks into the soil, water, and air. Almost all water contains some fluoride, but usually not enough to prevent tooth decay.
Drinking fluoridated water keeps teeth strong and reduces cavities (also called tooth decay) by about 25% in children and adults. By preventing cavities, community water fluoridation has been shown to save money both for families and for the US health care system.
