What are the beneficial effects of fluoride?
Fluoride has been shown to prevent tooth decay. This relationship was discovered in the early part of the 20th century when it was observed that residents of certain areas of the United States developed brown stains on their teeth. These stained teeth, though unsightly, were highly resistant to dental decay. In the 1930s, it was discovered that the prevalence and severity of this type of mottled enamel was directly related to the amount of fluoride in the water.
