My jaw keeps clicking and locking if i open it wide to eat and hurts sometimes my dentist said it could be arthritis what can i do to stop this?

TMJ/TMD: There is a good possibility that you have TMJ/TMD. A jaw that clicks or pops upon opening or closing or locks (closed- limited opening, open- hard to close, ) is usually a sure sign of a disk that is displaced which is a major symptom of TMJ. I would see a TMJ specialist. Try not to manipulate or force your jaw open or closed on your own. You can tear the disk and create a permanent injury.

TMJ: Sounds like TMJ. See a TMJ 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.
