In drawing these teeth the forceps should be thrust as high as possible and held firmly, while the fangs are loosened by moving the tooth from side to side, but from the multiplicity of fangs, rotary motion is not available. [Illustration: Fig. 80.—Left upper molar tooth and forceps.] [Illustration: Fig. 81.—Right upper molar forceps.] The _wisdom molars_ are often difficult to seize from being almost buried in the jaw; as they resemble a bicuspid in shape, bicuspid forceps (fig. 78) should be employed; if this fails to penetrate between the tooth and the alveolus, the narrow incisor forceps (fig. 77) can be driven up till it grasps the tooth. Not unfrequently the fang of this tooth in the lower jaw is curved backwards and prevents extraction when the tooth has been loosened; this difficulty may be overcome by pushing the crown of the tooth a little backwards so as to tilt the fang forwards out of place. When the molars are closely set, or the tooth to be extracted is overhung by its neighbour, it is often difficult to avoid tearing the gum extensively and even carrying away more than one tooth; tearing the gum is easily avoided by lancing it before applying the forceps, and slow and steady movements of the wrist usually prevent the latter accident, or the overhanging tooth may be filed away before the forceps are applied. The _inferior molars_ (fig. 82) have forceps, whose beaks are doubly grooved and pointed, to enable them to seize the neck on each side between the two fangs. [Illustration: Fig. 82.—Inferior molar tooth and forceps.] [Illustration: Fig. 83.—Elevator.] In _raising stumps_, so much decayed that the forceps will not hold them, the elevator must be employed; this instrument (fig. 83), straight, pointed, and a little grooved at the point, is thrust down between the alveolus and the tooth; the jaw being then the fulcrum, the elevator is the lever to push _forwards_ the fang; when thus loosened it is easily lifted out. In working with an elevator there is some risk of thrusting the point through the alveolus, and wounding the tongue or floor of the mouth, hence it should always be guided and covered by the left forefinger. In removing the fangs of incisors the narrow forceps are most useful, and should it not be possible to penetrate between the fang and the alveolus, the alveolar border may be included in the grasp of the forceps and brought away with the tooth. The injury thus inflicted is very unimportant and much pain is saved. After the tooth is extracted the mouth should be well washed with warm water a few times, the attending bleeding being of no importance, except in individuals of hæmorrhagic diathesis, in whom measures should be at once taken to arrest the flow.
