    made little or no progress; but in America it lias been slowly and steadily improving year by year, culminating in recent years in very great improve- ments. These have been introduced in order to overcome the several disadvantages connected with the ordinary methods of treating decayed teeth and adjusting Artificial ones. Experience has drawn up a long indictment against the use of plates and fastenings, the chief of which may be summed up in the following enumeration. Disadvantages of Old Methods. Teeth decayed beyond a small cavity are useless and are usually extracted, unless a very lengthy operation is performed to save them. All roots are useless, except those of front teeth, which can be pivoted. Pivot teeth, i.e., teeth fastened to the roots with a pivot, pin or screw, are only temporary opera- tions, rarely lasting more than a year or two. They do not preserve the root to which they are attached, and in which decay extends until the pivot loosens. Then, they are not cleanly, since particles of food can collect between root and tooth; they are never so strong nor firm as “ crowned ” teeth on the new method.
