The jaw is a very used joint for basic day-to-day activities like talking, eating, and drinking. Hence when jaw pain arises it can be more than a nuisance. Jaw pain affects 5-12% of the general population, affecting women more than men. Temporomandibular disorders (TMD) is a blanket term used for jaw pain and dysfunction by problems with the joint or its associated musculature.

The temporomandibular joint (TMJ) is composed of the temporal bone (the upper joint) and mandibular bone (the lower joint) separated by the disc. Opening biomechanics includes the lower joint hinging and the upper joint sliding together. Jaw movement involves various muscles including the temporalis, masseter, medial and lateral pterygoids. These are known as the muscles of mastication (chewing). When the muscles are dysfunctional this can prevent the movement of the jaw in a coordinated fashion.



Symptoms of TMD

TMD can be one-sided or two-sided. Pain referral sites may include the teeth, temple, ears, sinus areas, side of the neck, upper shoulder region, headaches around and behind the eyes known as “tension-type headaches,” and pain radiating around the TMJ itself.

TMD Causes

TMJ disorder can be caused by:

- The muscles that control the jaw and the connecting neck and shoulder muscles.
- Direct trauma including head or neck injury.
- Internal disorder of the joint, or a dislocated or displaced disc.
- A degenerative joint disease in the jaw joint, like arthritis.
- Dental problems including clenching and grinding teeth.



Chiropractic Treatment

When TMD is suspected, a thorough history including medical and dental is done. Physical examination of the TMJ, neck, and surrounding structures is performed including observation, mandibular gait, and special orthopedic tests. Treatment involves specific soft tissue therapy and gentle chiropractic adjustments, rehabilitation, and further education including things to avoid and things to do.

Common TMJ rehab may be prescribed including muscle release and specific jaw opening and strengthening exercises. Lifestyle changes such as avoiding eating chewy and hard foods may be advised as it can be difficult for patients with TMJ as they can add more stress to the affected areas. A health practitioner who is helping you deal with TMJ may request you to not eat certain foods. Patients with TMD should pay attention to any abnormal pressure or triggers on their jaw that may cause soreness from jaw movement.

In addition, activities such as pounding sports (i.e. running, soccer, and basketball), smoking, holding your phone to your cheek, playing the violin, or the use of a CPAP machine are also options to reconsider if you're dealing with TMJ. These may be requested when consulting with your health care provider.
