Arboreal snakes when they bite its a different issue. I don,t think they will lose teeth that easy. As i have mentioned before, my ATB bit me countless times and never lost a tooth i think. Maybe because they have a different set of teeth or because the bites are just defensive. My GTP bit me several times and never lost a tooth. As for bacteria, i think they are somewhat immune to that as my snakes eat live prey and they bite it and get also blood and bacteria in their mouths. And sure i would love if they don,t bite, but how can i convey that to my ATB? I was able to reduce the number of his bites and tame him partially not totally
