Can Fluoride Reverse Tooth Decay?
It’s interesting to know: • Fluoride prevents and can even reverse tooth decay. • More than 60 percent of the U.S. population on public water supply systems has access to water fluoridated at approximately 1 part fluoride per million parts water — the optimal level for preventing tooth decay. What is fluoride? Fluoride is the name given to a group of compounds that are composed of the naturally occurring element fluorine and one or more other elements. Fluorides are present naturally in water and soil. What is fluoridated water? Virtually all water contains some amount of fluoride. Water fluoridation is the process of adding fluoride to the water supply so that the level reaches approximately 1 part fluoride per million parts water (ppm) or 1 milligram fluoride per liter of water (mg/L); this is the optimal level for preventing tooth decay. Why fluoridate water? In the early 1940s, scientists discovered that people who lived where drinking water supplies had naturally occurring fluorid
