The roots of these teeth are generally straight, but occa-sionally the apex is curved to the distal. THE CUSPIDS. 32. We have four cuspids, one on each side in the upper,and one on each side in the lower jaw. They are sometimescalled canine teeth, or eyeteeth. They are situated at the an-gles of the mouth, between the lateral incisors and the first bi-cuspids. They are third from the median line, and are large,and strong teeth of simple form, firmly implante

They are situated at the an-gles of the mouth, between the lateral incisors and the first bi-cuspids. They are third from the median line, and are large,and strong teeth of simple form, firmly implanted in the alve-olar process by a long, strong root. THE UPPER CUSPIDS. 33. The labial surface of the crown of the upper cuspid(Fig. 18) is a little narrower in the mesio-distal direction thanin the central incisor, with nearly equal length from the pointof the cusp to the gingival line. Instead of a straight, or onlyslightly curved cutting edge, as in the incisors, the central por-tion of the crown is extended nito a well-formed point (a),.
