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).
Underneath the surface enamel and cementum is a substance called dentin, which makes up the main body of the tooth. Within the dentin, in a space in the center of the tooth, is the dental pulp, a soft, sensitive tissue that contains nerves and blood and lymph vessels.
