A single pair of slightly anteriorly inclined teeth is located at the apex of the lower jaw. Occasionally another pair of functional teeth develops and erupts, but when this happens the anterior pair is always the larger. Vestigial teeth, up to 10 or 20, are sometimes present in the upper or lower jaws.
Only adult males have erupted teeth, teeth in females and young animals do not erupt above the gumline.
Adult teeth are pear shaped with a bulbous root. Adult male teeth can reach 5 cm in length, female teeth are smaller.
