Eli5: why is when a bone shatters it can rebuild itself but when a tooth gets a hole in it it just keeps eating away at it
In: Biology
Teeth can heal back theoretically but the issue is there’s like a jillion times more bacteria in the mouth than in the body itself so the bone doesn’t have continued bacteria exposure eating away at it. If someone had a mutated tooth that’s not in their mouth and people preserved it, it’d be harder than bone because it wouldn’t have the crap tons of bacteria our mouths do (from eating, drinking and filtering air when we breathe) that slowly eats away at teeth.
