tooth
A hard structure, embedded in the jaws of the mouth, that functions in chewing. The tooth consists of a crown, covered with hard white enamel; a root, which anchors the tooth to the jawbone; and a “neck” between the crown and the root, covered by the gum. Most of the tooth is made up of dentin, which is located directly below the enamel. The soft interior of the tooth, the pulp, contains nerves and blood vessels. Humans have molars for grinding food, incisors for cutting, and canines and bicuspids for tearing.
