Pig head showing teeth and left tusk.
The incisor teeth are visible at the front of the top and bottom jaws. The single canine teeth on each side of the top jaw are about about half way along the jaw. On the bottom jaw, the canine teeth are tusks; one on each side - the left one is visible here. Visible behind the tusk are the premolars and molars, which are at the back of top and bottom jaws on both sides.
