608 EXTRACTION OF TEETH.

points of the beaks of the sjx'eial molar forceps (Fig. 485 or 40 placed in between the roots on each side of the tooth. Care should
be exercised to avoid inelndino; a ])ortion of the tono:ue or soft tissues
of the floor of the mouth in the force})s. If the forceps are not well
placed the wrono; tooth may be extracted, as it is ])ossible for them to
slip in between two teeth.
In loosening these teeth the out-and-in motion is used, and as they are
wedged in it is often necessary to continue this motion while extracting
them from their sockets. At times it is advisable to move the tooth out-

wardly after it has been slightly lifted from its socket. Occasionally the
roots diverge so far that either the crown has to be broken from the
roots at their bifurcation or the tooth divided in the line of bifurcation
with splitting forceps ; each root being then extracted separately.

THE SECOND MOLAR.
The roots of this tooth are not as diverging as those of the first
molar, as may be seen by examining Fig. 514, nor is the tooth wedged
in as tightly as in the case of the first molar.
The out-and-in motion is required for these teeth, using the same
precautions that are necessary in the extraction of the first molar.
