Sometimes teeth that have fully erupted out of line when brought into proper position extend below the lme of the cutting edges of their neighbors and the rest of the teeth in the arch. Any attempt to reduce their elongation by forcing them up into the socket would not only be extremely difficult, but in many cases futile. . The better plan, if the disparity in length be not great, is to grind off their cutting edges somewhat, and thus 'accomplish the desired end m a very simple manner. FIG. ieo.

When the malposed teeth have been brought into position their rounded and unworn cutting edges are apt to contrast strongly with the abraded edges of their neighbors. By so dressing the incising edges of the unworn teeth as to resem- ble those next to them, greater Harmony of expression will result. Fig. 162 illustrates a case in which the worn condition and varying length of the lower anterior teeth presented a very unsightly appearance, and Fig. 163 represents the improvement made by reducing the length of certain ones and straightening the edges of others by grinding.
