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 have the ability to heal from the inside out (laying down tertiary dentin to protect the pulp) but not the outside in. Like others have said before, there’s no scaffolding for teeth to build on to repair. Bones are totally inside the body so the cells can rebuild much more efficiently. Hope that makes a little sense
