3. Enamel Coats Each Tooth

Enamel is the translucent layer that covers the visible part of the tooth. It is the hardest tissue in the entire body. While all teeth grow in with a layer of enamel, this layer can be slowly stripped away and leave the sensitive parts of the tooth exposed. Once enamel is gone, it does not grow back and dental problems often follow. Enamel also insulates the teeth and protects them from harmful substances into which they may come in contact. Avoiding certain foods and consistent cleaning can protect tooth enamel.
