Theanterior roots of the lower molar teeth being largerand more prominent than the posterior, thesegrooves of a width and depth to correspond, i. e., INSTRUMENTS FOR EXTRACTING TEETH. 121 the anterior should be deeper and wider than theposterior. Forceps thus made, when fairly applied,,seize the tooth firmly ; there is no danger of theirslipping, and very little danger of ever breaking atooth in attempting to extract. With an instrument thus shaped, the mere act ofapplying it is often sufficient to remove the tooth,for these long tapering points having fairly entered Fig. the bifurcation, the upper side of each point as it isfurther forced in, bears hard upward on the tooth,Avhile the other bears as hard upon the edge of thealveolus, thus acting like two little wedges, and with11 122 INSTRUMENTS FOR EXTRACTING TEETH. sufficient force to raise the tooth from its socket,by simply closing the instrument upon the tooth. Another great advantage of this form of beak is,that when the crown of a tooth has been broken offabove the bifurcation, that is, without separating itsroots, the gum can be dissected from the alveolus fora short distance, and the instrument applied in theline of the bifurcation, and low enough down tosecure its points entering there, when with but aslight force upon its handles, th
