My symptoms are jaw joint pain, jaw clicking, dizziness, grinding, chewing difficulties, neck pain and limited mouth opening. What could it be?
Dislocated jaw. It sounds like you have a dislocated jaw and the muscles that move and support your jaw movement are causing problems. I would go to your dentist and see if he/she can help you or find someone who can first determine why your jaw is dislocated and then address how to correct the cause. Use a splint first (reversible) before you attempt irreversible corrections. Good luck.
TMJ. Visit your dentist who will treat your condition: tmj.
TMJ/TMD. TMJ disorder. Can be very complicated. See TMJ/TMD expert. Any dentist can be a TMJ expert with the proper training and experience. Most commonly, oral surgeons, prosthodontists, and orofacial pain specialists. Ask your MD, your dentist and your dental society for referrals.
