What is TMJD?
When the temporomandibular joint becomes injured or damaged in some way (possibly by a sporting injury, or teeth grinding at night), this can lead to TMJD (temporomandibular joint dysfunction). Other causes of this condition include natural misalignment of the jaw or teeth, joint degeneration due to osteoarthritis, or inflammation as a result of rheumatoid arthritis.
There are several signs and symptoms of TMJD, with most of them affecting the jaw area. Pain in the joint itself, a clicking when the jaw is moved, sore jaw muscles and a complete locking of the hinge can all be indicative of TMJD. Popping in the ears and pain in the temple are also tell-tale signs that TMJD may be present.
