<s>[INST] My jaw bone is degenerated. Therefore, it hurts. will it grow back? I m 14 years old taking one aleve in the morning with vitamins (even B-100). Then at night I take tylenol 3 with codeine . is it possible to grow back at such a young age? [/INST] Hello, in your problem you did not tell about the reason of this bone degeneration......... there are so many reasons of degeneration like genetic, trauma, tooth extraction, developmental deformities, osteomyelitis,dentures, periodontal diseases etc............it is very important to have a healthy bone for tooth development........I will suggest u to go to dentist get the whole mouth examination.........after examination only we can find the exact diagnosis, and accordingly you should go for proper treatment........take care Chat Doctor.  </s>
