We've all heard that enamel is important to tooth health. But what happens when your enamel doesn't develop properly? Enamel dysplasia is a condition that affects the normal levels of one's tooth enamel. A form of exceptionally hard tissue, enamel acts as a protective outer shell to cover the part of the tooth that contains the sensitive pulp, dentin, and cementum tissues. The condition is usually caused by hypoplasia, which is the tooth enamel's malformation; or by enamel that doesn't adequately calcify.
