TMJ is the short form for the Temporo-Mandibular Joint (where the jaw connects to the skull on both sides of the head). Approximately 20% of the population is affected with some form of TMJ dysfunction. Dysfunction often produces a variety of symptoms such as jaw pain, neck pain, headaches, limited jaw movement, and clicking, locking or popping sounds in the joint. There are many possible causes for these symptoms, including overuse of muscles as well as biting, grinding and clenching habits. Proper examination and diagnosis is important because the good news is that approximately 75% of cases respond well to a number of simple conservative treatments available at Chiropractic Plus.
