Each tooth consist of three parts a crown, or body, projecting above the gum, one or more fangs imbedded in the jaw, and the neck, or intermediate part In some animals one or more of the teeth are modified into tusks which project from the mouth, as in both sexes of the elephant and of the walrus, and in the male narwhal. In adult man there are thirty-two teeth, composed largely of dentine, but the crowns are covered with enamel, and the fangs with a layer of bone called cementum.
