The Importance of Fluoride
Every day, the enamel (outer layer) of your teeth loses and gains minerals. Demineralization (loss of minerals) occurs when bacteria in your mouth produce acid, which weakens your teeth. Remineralization, in contrast, refers to the process by which minerals such as fluoride, calcium, and phosphate are deposited into your teeth. Ideally, these two processes balance each other. When too many minerals are lost without remineralization, enamel weakens and can lead to tooth decay. In more severe cases, it can result in tooth loss.
