Bone loss in tooth, any way to regrow it?

See dentist: See a dentist or periodontist to find out how much bone has been lost and the best way to treat this problem. Prevention is often the best treatment.

If your question is.: If you are referring to re-growing the enamel of your tooth, then the answer is basically no. Slight decalcification can be somewhat repaired with better oral hygiene and the use of re-mineralizing prescription toothpastes such as mi toothpaste. Basically, lost enamel is gone forever and would need to be repaired with some dental restoration if extensive enough to warrant it.
