Tooth decay is caused by certain bacteria in the mouth. When a person eats sugar and other refined carbohydrates, these bacteria produce acid that removes minerals from the surface of the tooth. But fluoride can stop or even reverse the tooth decay process — it can help re-mineralize tooth surfaces and prevent cavities from forming. Adding fluoride to water systems is one of the most effective ways to prevent tooth decay.
