Why is it that every part of the human body heals itself except for the teeth?

Why don%26#039;t teeth heal like everything else does?

Why is it that every part of the human body heals itself except for the teeth?
Because the cells that make bone and the cells that make enamel are different. The cells that make enamel (amneoblasts) stop building enamel when a tooth is fully developed. Cells that build and repair bone (osteoblasts) are always working. It%26#039;s just biology.
Reply:You%26#039;re wrong. Hair doesn%26#039;t heal either. It replaces itself, just as a tooth does once. Hair continues to replace itself, but once it%26#039;s beyond the scalp, it%26#039;s dead as a door nail.
Reply:Teeth can also %26quot;heal%26quot; to a certain degree.
