FILLING TEETH 103

pluggers used with a mallet, and thin flat burnishers,
are all useful for accomplishing this.
Whenever non-cohesive gold can be successfully
used it will be found, in many cases, to effect a
saving of time, as far as the insertion and con-
solidation of the gold are concerned, and the work
is accomplished with less eye-strain. As far as the
excellence of the work is concerned, it must be
admitted that, although in certain cases a perfect
adaptation may be accomplished with greater ease
and certainty, there is no possible adaptation with
non-cohesive gold that cannot be equalled with
cohesive gold ; the latter has a wider range of
employment, and a coherent solidity and hardness,
that are essential in many cases.
Finishing Gold Fillings.—When the filling of a
cavity is completed, the surface of the gold should
be further consolidated and rubbed somewhat smooth
with a burnisher, using firm pressure. The gold is
then trimmed to the desired shape, the edges
brought to fine lines, and the filling generally made
fairly smooth with files, fine cut burs, stones, emery,
or sandpaper strips and discs, &c., using one or more
of the above as necessary. The burnisher should
again be thoroughly used, and, if desired, the filling
may be finally made as smooth as possible with a
