INFERIOR MOLARS. 377
these teeth from the right side with the ordinary for-
ceps, there is great clanger of undue pressure on the
anterior contiguous teeth ; which is to be avoided by
directing the pressure backward in the operation.
And there is also danger of injuring the upper teeth
with the forceps ; which may be obviated by wrap-
ping the point of the instrument with a small napkin.
In the removal of the inferior molars of the left
side, the application of force is the same—an inward
and outward movement—but the handles of the for-
ceps occupy different relative positions to the teeth
to be extracted passing directly out at the front of
;
the mouth, instead of at one side. In consequence
of this arrangement, the operator can not exert the
same force on them, as, with the proper forceps, on
those of the right side. Yery little traction can be
employed in connection with the oscillating move-
ment, but the attachment must be almost wholly
broken up before beginning to lift the tooth from the
socket. But in extracting the teeth on the right
side, with the proper forceps, traction is always com-
bined with the inward and outward movement.
In the extraction of the roots of these teeth, little
difficulty is experienced after the decay has pro-
ceeded so far as to effect their separation. They are
then embraced with the appropriate forceps, and
removed as single roots are elsewhere. These for-
