For the lower incisors a very narrow forceps is necessary. The beaks (fig. 77) should be curved at the joint sufficiently to form an angle of 25° with the handles, that the latter may clear the upper jaw. The edge of the beaks is crescentic, similar to that of the upper incisors. These forceps are also very useful for removing roots, as their fineness enables them to sink between the stump and the alveolus with ease.

For the bicuspids, beaks with crescentic edges also are used, but the inside of the beak is more hollowed to fit the round neck of these teeth (see fig. 78). All the bicuspids can be drawn with the same pair, but it is convenient to have forceps bent at the joint to clear the upper jaw when extracting a lower bicuspid (see fig. 79).
