Do not blame anyone else, when you get bitten, not even if it is someone else's animal. If you get bit, it is usually your fault or nobody's fault. Sometimes a snake tooth will be lost, when it bites. This is a normal part of life. If one is left embedded in your skin, treat it as a splinter, though a tooth usually comes out wasier than most splinters.
Reptiles are physiologically incapable of having rabies, a definite advantage over dogs and cats.
Most turtle bites are pinches and will not draw blood. Larger tortoises can have a good bite, though. Especially small children's soft hands should be kept in a save distance. The most unpleasant part of being bitten by a turtle is often, to get the animal off. My reptile is skittish.
