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).
Dental anatomy (or tooth anatomy) is a field of anatomy dedicated to the study of tooth structure. 1  Enamel Enamel is the hardest and most highly mineralized substance of the body ; 96% of enamel consists of mineral, with water and organic material comprising the rest. Enamel covers the crown of the tooth and varies in thickness over the surface of the tooth ; it is often thickest at the cusps, up to 2.5 mm, and thinnest at its border. The normal color of enamel varies from light yellow to grayish white ; since enamel is semi-translucent, the color of dentin and any restorative dental material underneath the enamel strongly affects the appearance of a tooth.
