FILLING TEETH 93

densed and made solid at all parts, working tlie gold
principally towards the angle formed by the cervical
wall and the floor (Figs. 4 and 5). It is import-
ant for the gold to be worked in this manner, for if
it should extend in a thin layer over the margin, it
will be apt to curl up, or be drawn away during the
subsequent manipulation, and either a slight space
or a depression left at this part, causing, in all prob-
ability, failure of the filling. When the cervical mar-
gin is thickly covered and the gold well wrapped over
it, the filling is built up, towards the occlusal surface,
preferably with a small foot plugger if thin tape is
used, in such a manner that the gold is worked with
the point or toe well against the walls, and into any
grooves or angles that may have been made here,
and then by placing the heel of the plugger in the
cavity, and the toe outwards, work the gold carefully
up to and over the edges, and build up the external
surface convex, so as to restore contour, thoroughly
consolidating the gold, including the surface, as the
work proceeds (Figs. 6 and 7). If there is any
difficulty in wrapping the gold over the margins,
use for this purpose a hand plugger with a broad
condensing surface (Figs. 8 and 9). When the
filling reaches the occlusal surface, carry it well
across the floor of the occlusal step cavity, build
up the back wall of the step, and complete the
