"tooth to bone attachment is so firm in chameleons that if injury to the oral cavity occurs, teeth are not lost, as would happen in mammals. Rather, a piece of the jaw with several neighbouring teeth is broken off"...this happened to one of the Parson's females I had many years ago...

"Interestingly, the calcium and phosphorus content was lower in the jaw bone than in the teeth, especially at the juvenile stage. This could explain the broken jaw bones during fights between animals, as the bone is much weaker than the junctional tooth–bone areas"...I found this to be quite interesting as well.
