Tight teeth and gums after genioplasty. Could this be nerve damage or scar tissue?

Hello, I had a sliding genioplasty 3 years ago and my lower teeth have been hurting, especially this past year. They are tight and hurt ( like dull toothache ) My lower gums feel a bit tight too. Could this be from scar tissue in the chin or under the incision? Or will it be nerve damage? Any help appreciated.
