Normal occlusion lateral view

This prepared skull of a wild rabbit shows the normal relationship of the upper and lower teeth. The tip of the lower (mandibular) incisor rests against the peg tooth (secondary incisor) that sits just behind the large upper (maxillary) incisor (arrow). The enamel on the rostral aspect (front) of the incisors is thicker than on the caudal aspect (back). This helps to maintain the sharp edge to the tooth. The tips of the incisors are kept sharp by moving the upper and lower teeth in such a way that they they grind the tips to a sharp edge. There are five lower cheek teeth. These are numbered. The six upper cheek teeth are also numbered.
