This is a lateral view of an 8-year-old horse’s teeth. The first dental star appears on the central incisor when the horse is an 8-year-old. In some instances, the first stages of a dental star (a dark yellow or brownish-yellow line) appears on the occlusal surface of the intermediate incisor. When viewed laterally, the upper and lower incisors are at a more oblique angle than before.
