TOOTH (שֵׁן, H9094; ὀδούς, G3848). A small, hard body fixed in a dental socket, technically called an alveolus, in either of the jaws. It serves to seize, cut, tear and grind nutritious substances. In general a tooth has the shape of an irregular cone. In a child there are twenty deciduous or milk teeth. In the adult the teeth are thirty-two in number: sixteen in each jaw, namely, four incisors, two canines, four bicuspids and six molars. The crown of the tooth is the part that appears outside the dental socket. Within the crown is a central pulp cavity containing blood vessels and nerves. When injury occurs to this pulp cavity, toothache often results.
