TMJ or the tymporomandibular joint, is the most constantly used joint in the body.

The TM joint is a small joint located in front of the ear where the skull & lower jaw (mandible) meet. This joint allows the lower jaw to move & function. The TM joint is like a ball & socket joint, the ball portion is the condyle, the socket is called the fossa. Between the ball & socket is a disc made of cartilage that cushions & absorbs stress & allows the condyle (the ball portion) to move easily as the mouth opens & closes.

Behind the TM Joint, the disc attaches to nerves & blood vessels that can be very sensitive. Ligaments hold the disc in place & muscles help stabilize the joint as well as move the lower jaw.

Teeth also play a roll, if they don't fit properly together, stress can result & cause problems with the disc, ligaments & muscles. Tauma to the joint can also affect the joint & how it functions.

    Triggers of TMJD
  • Clenching & grinding teeth
  • Sprain or strain of joint muscles & ligmaments causing Muscle spasms
  • Jaw position
  • Arthritis
  • Dislocation of the disc or joint
    Signs & Symptoms Possible with TMJD
  • Painful clicks or pops when opening or closing the mouth
  • Sore Jaw or facial muscles upon awakening
  • Pain in TMJ area
  • Locking of the jaw
  • Difficutly in opening the mouth
  • Frequent headeach or neck aches
  • Clenching or grinding the teeth

These symptoms can also be associated with a disorder called myofascial pain syndrome~(MPD). A specialist in oral or maxillofacial surgery can diagnose this disorder when evaluating your need for TMJ treatment.

Treatments vary from jaw rest, soft diets, oral splints, medication, time , to surgery. Treatment depends on your jaw anatiomy .Finding a maxillofacial surgeon experienced in TMJ treatment is essential.

Muscle Pain or stains will usually be treated with a soft diet, tylenol and/or ibuprofen. Clenching/grinding problems may be treated with antidepressants in low doses to improve your sleep patterns & decrease the intensity of the clenching & grinding. Dental splints or mouthguards properly fitted to you may also decrease the intentsity of clencing & grinding & wear on the teeth.

Disc displacement can be treated the same as above or may require additional treatment such as surgery. It is important to seek medical attention & get an accurate diagnosis of disc displacement- their are 2 stages one where the disc is partially dislocated (early stage) or when the disc is permantly dislocated (later stage).An MRI will show your jaw anatomy on opening & closing which can determine your diagnosis. Seeking treatment as early as possible will be advantagous to your outcome.
