My son was recently hit in the mouth by a baseball. His right front tooth and the one next to it was pushed back. The dentist straightened his teeth and attached a temporary brace to them. Last week, he took the brace off, but informed us that the teeth had nerve damage and were "dead". He now says they will require root canals.

1. Should he have checked for this nerve damage sooner, and could he have done anything about it?

2. Is nerve damage always permanent?

3. Is there any new technology/procedures to reverse nerve damage?

4. What are possible future problems?

Thanks.
