An adult molar Cross section of an adult human molar.

The "root" of a tooth is the part located within the jawbone socket. This root is covered by cementum, a bonelike material, and is anchored by the periodontal membrane. A root canal refers to this part of the tooth's pulp cavity or a dental procedure to save a tooth by cleaning and filling this area. Teeth themselves are hard structures in the mouth used for eating and defense, consisting of a crown (visible part) and one or more roots (supporting part).1234
