Horse's teeth at eight years of age the cavity has largely disappeared at six years (Fig. 19), the lateral at seven years (Fig. 20) and the corners at eight years of age (Fig. 21). The date-cavities in the incisors of the upper jaw do not dis- appear as regularly as the lower, and are less to be depended upon. In general, the date- cavities disappear from the central up- per incisors from nine to nine and a half years; from the lateral upper incisors from ten to ten and a half; and from the upper corner incisors from eleven to twelve years. Date-cavities sometimes persist in the upper incisors for a longer period, especially in horses that are stall-fed. In examining date-cavities, a careful com- parison with the preceding and succeeding years should always be made. After a date-cavity is worn out, a small black spot called a "dental star" remains, and frequently a small cavity, which should not be mistaken for a date-cavity. In young horses, the incisor teeth are broad from side to side, and approach the perpendicular with reference to the jaw. As the horse gets older, the incisors wear down, becoming nai-rower from side to side and wider from before back, so that the upper surface of Fig. 22. Horse's teeth at ten years of age.
