Teeth are not made of bone, but to a certain extent of multiple tissues of varying density and hardness.
The unrestricted make-up of teeth is similar across the vertebrates, although there is sizeable modulation in their shape and position. The teeth of mammals drink esoteric roots, and this decoration is also initiate in some fish, and in crocodilians.
