Mouth and jaw guide
5 min readClicking jaw
A clicking jaw is common and may not need treatment if painless, but pain, locking or limited opening should be assessed.
Jaw clicking, popping or grinding noises can happen when opening, closing, chewing or yawning. A click by itself does not confirm a jaw joint disorder.
Assessment is more important when clicking is painful, worsening, linked with locking, or limits opening and closing the mouth.
