Twenty-one Years (Figs. 119,120,121).—The teeth become so hori- zontal that, looked at in front, the inferior ones are scarcely seen unless the head is well raised. The triangular interspaces at the base of the superior incisors increase in size and the convergence of the free ends becomes more marked. In profile, the jaws are seen diminished in size; the inferior corner teeth have become almost horizontal and have worn off the notch on the superior corners. Tlie wearing surfaces of these teeth become elongated from in front to behind and have lost their tri- angular shape. The tables of the superior pinchers and intermediate teetli are elongated from in front to behind and distinctly triangular; they are generally leveled.
