corne in contact with the contiguous teeth, in the
rotary motion made to break up the attachment.
The same principle in regard to the width of the for-
ceps is to be observed for the lateral incisors and
cuspids. The ordinary straight, root forceps, may be
employed for the extraction of the lateral incisors

though, for this purpose, it is desirable that their
beaks be somewhat thinner than usual. For the
superior cuspid teeth, the ordinary bicuspid forceps
are frequently used ; but their beaks are commonly
too narrow, and those of the central incisor forceps
too thin. The cuspid forceps should be about as
wide as those for the central incisors, with the thick-
ness of the bicuspid forceps (Fig. 62), and with a

greater concavity, so as to fit the neck of the tooth.
The superior bicuspid forceps have narrow, thick, and
quite concave beaks, and the instrument is straight,
or nearly so ; though for the second bicuspids,
especially in a small mouth, it should have some
anterior curvature. (Fig. 63.) One pair of forceps

will serve for both sides, though it is desirable to
