Figure 1. Crown of the tooth. The teeth are made up of two major parts: the crown and the root. The crown of the tooth is what is visible in the mouth (Figure 1). The root of the tooth is the portion which normally not visible in the mouth and is anchored within the bone (Figure 2).
The visible part of the tooth is called the crown. It is made of enamel, an extremely hard, non-living substance. Because it contains no living cells, tooth enamel cannot repair damage from decay or from wear. Only a dentist can correct these conditions.
