The hard parts of teeth are principally made up of dentine, or ivory, and a very hard substance called enamel. These are variously combined in different animals. 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. Of the eight teeth on each half of each jaw, the two in front are incisors, then come one canine, cuspid, or dog tooth, two bicuspids, or false molars, and three molars, or grinding teeth. The milk, or temporary, teeth are only twenty in number, there being two incisors, one canine, and two molars on each half of each jaw. The last molars, or wisdom teeth, usually appear long after the others, and occasionally do not appear above the jaw at all. "How sharper than a serpent's tooth it is To have a thankless child !"
