Temporo-Mandibular Joint Pain (TMJ)
Why Does TMJ Occur?
The temporo-mandibular joint is the joint where your lower jaw
bone is connected to the temporal bone of your skull. It is covered
with a thin layer of cartilage and separated by a small disk.
This joint is almost constantly in use as you eat, speak and
swallow.
Pain is experienced in this joint due to wear and tear; stress
that expresses itself in grinding or clenching the teeth; misalignment
of the upper and lower jaws; and, sometimes, arthritis.
What Are the Symptoms?
TMJ pain can express itself in any of the following symptoms:
Causes of TMJ
TMJ pain is often caused by wear and tear, or the overuse, of
the joint due to stress, anxiety and tension. These feelings
cause many people to clench their jaws or grind their teeth,
putting extra strain on the joint and muscles surrounding the
joint.
Another cause of pain is misalignment of the upper and lower
jaws that can occur naturally or as the result of an injury.
Improperly aligned jaws cause an uneven bite, producing additional
wear and tear on one joint or the other.
In addition, since the TMJ is a joint like all other joints
in our bodies, it can also suffer the effects of osteoarthritis,
rheumatoid arthritis, and other forms of joint inflammation.
Diagnosing TMJ
If you are experiencing any of the symptoms listed above on
a regular basis, you will want to speak with your doctor or dentist.
He/she can
diagnose
or rule out TMJ pain by considering your symptoms and performing
a physical exam. In some cases, he/she may also perform and x-ray
or MRI scan.
Treatment Options
The first, and most obvious, thing your doctor will ask you
to do is to reduce the amount of stress on the joints, either
by finding ways to relax (and stop grinding or clenching your
teeth) or to stop chewing gum and other tough foods. In many
cases, some additional measures may be taken.
Medication
Over-the-counter anti-inflammatory medications (such as ibuprofen,
motrin, etc.) may be recommended to alleviate some of the pain.
For more severe pain, a prescription anti-inflammatory may be
given.
Dental Treatment
For some sufferers, dental work or the use of a dental appliance
may alleviate the pain associated with TMJ. Simply improving
the bite or the use of a biteplate to cushion grinding teeth
may make a marked improvement.
Surgery
In extreme cases, surgery may be required to repair or remove
the disk between the jaw and the temporal bone. More about facial
