The instrument must consequently he thrust with considerable force within these structures, until it reaches a firm and sound part of the tooth, and there be made to grasp it secure])', but cautiously. In reaching this part some diffi- culty will occasionally be met with. Where the decay has advanced on one side,—or it may be on more than one side,—below the level of the alveolus, the instrument, instead of fixing itself beyond the decayed cavity, will be very apt to slip into it, and thereby break down the remains of the tooth. And again, when the alveolus is of dense and hard consistence, or where its walls are very thick, as is often the case in the neigh- bourhood of the lower wisdom-teeth, it often becomes a matter of great difficulty to insert an instrument between the surface of the fangs and the socket enclosing them. Where the walls, again, are thin but dense, and firmly attached to the fangs, they are, on the other hand, apt to be seized along with the tooth, and to increase the difficulty of its removal. The detachment of a tooth from the alveolar walls surrounding it should, as has been already said, be made in that direction where least](https://iiif.wellcomecollection.org/image/b28101224_0082.jp2/full/800%2C/0/default.jpg)
