5. Locking of the jaw
If you find that your jaw is locking – it is difficult to open or close – the issue could very well be the result of TMJ disorder. Since this condition can displace the ball of the jaw joint, it can prevent the jaw from opening or closing properly, which can make it incredibly difficult to close or open the mouth. If your jaw becomes locked in place, it is very likely that you will also experience pain, which can be excruciating.
The jaw may not become completely locked; however, opening and closing it could become a real challenge. In addition to the jaw becoming completely locked or having difficulty opening and closing it, you will likely also experience a great deal of pain whenever you try to open or close your mouth. The pain can be mild and subside, or searing and last a long time.
