The importance of tooth enamel
Tooth enamel is an essential component of healthy teeth. It is a hard, outer layer that covers the visible portion of the tooth, known as the crown. Enamel serves as a protective barrier, shielding the underlying dentin and pulp from damage and decay caused by bacteria, acids, and other harmful substances. It is the hardest substance in the human body, with a rating of 5 on the Mohs scale of mineral hardness, which measures the scratch resistance of various minerals.
