- Fluoride found to reduce dental caries
Background
An investigation into why so many residents of certain communities in Colorado had severe tooth discoloration led Dr. Fredrick S. McKay to suspect that an ingredient in the water supply was causing the problem. Although the discolored teeth were unsightly, they were highly resistant to dental caries (tooth decay). In 1931, it was discovered that the water supplies of these communities had high levels of naturally occurring fluoride. It was discovered that fluoride ingested in appropriate amounts could decrease the incidence of dental caries.
Impact
Widespread use of fluoride has been a major factor in the decline in the prevalence and severity of dental caries in the United States. When used appropriately, fluoride is both safe and effective in preventing and controlling dental caries.
