I had an operation to correct a protruding jaw, now my teeth are causing me huge problems. help?

Need consult: If not done properly such surgery can cause dental problems. You need to consult with an oral or maxillofacial surgeon do determine what has happened and how to fix this.

Talk to your dentist: Not enough details to say, but if you had corrective jaw surgery, i suspect that you have an orthodontist, an oral surgeon, and a general dentist as a team by your side. Your treatment may still be in progress, but be sure that you talk to one/all and let them know your concerns.

Get opinion: Depending upon what the "problems" are, they may or may not be at all related to the fact that you had jaw surgery. It is important that you return to your dentist and oral surgeon to investigate the cause and possible solutions of your "problems.".

Check w team: In addition to oral surgeon the team treating you should have included an orthodontist, a restorative dentist, and if necessary a periodontist. Just fixing jaws doesn't solve all problems. You need a team approach, coordinated by your restorative dentist. Consult wit him asap.
