I have hope that this is true. So much of the treatment and prevention is focused on protecting the surface of the teeth which is certainly a major consideration. However, there are health conditions that seem to effect the teeth and enamel that are not born from a tooth problem. A symptom of celiac is holes in the enamel. I don't know if these heal though after the diet is adjusted for celiac.

Bones can heal so it seems to follow (to me anyway) that perhaps teeth can heal too. Again, I hope this is true. I agree that conditions would have to be right in order for it to happen.

There are 'those people' that never get cavities. Would be interesting to know what's going on there.
