  Tooth \Tooth\ (t[=oo]th), n.; pl. Teeth (t[=e]th). [OE.
     toth,tooth, AS. t[=o][eth]; akin to OFries. t[=o]th, OS. & D.
     tand, OHG. zang, zan, G. zahn, Icel. t["o]nn, Sw. & Dan.
     tand, Goth. tumpus, Lith. dantis, W. dant, L. dens, dentis,
     Gr. 'odoy`s, 'odo`ntos, Skr. danta; probably originally the
     p. pr. of the verb to eat. [root]239. Cf. Eat, Dandelion,
     Dent the tooth of a wheel, Dental, Dentist, Indent,

     1. (Anat.) One of the hard, bony appendages which are borne
        on the jaws, or on other bones in the walls of the mouth
        or pharynx of most vertebrates, and which usually aid in
        the prehension and mastication of food.
        [1913 Webster]
     Note: 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.
           [1913 Webster]
