Agamids and chameleons share what are known as acrodont teeth: a morphology in which the teeth are fused to the jaw bones, and are therefore not replaced during the animal’s life (however, socketed teeth – which are replaced continuously – are usually found at the front of an agama’s jaws).

sionnach commented on the word acrodont
1. Having the teeth attached to the upper surface of the jaw rather than encased in a socket, a condition seen in many lizards and fish.
2. The teeth of some reptiles that have no roots and are joined to the jawbone.

Thanks sionnach.
