what causes your jaw to lock on one side
However, one of the most common causes of lockjaw, as already mentioned, is TMJ disorder. TMJ disorder refers to a syndrome that affects the temporomandibular joint, commonly called the TMJ, which connects the jaw with the bottom of the skull.
Temporomandibular disorder (TMD) is a problem affecting the 'chewing' muscles and the joints between the lower jaw and the base of the skull. Doctors sometimes refer to the condition as myofascial pain disorder.
