Causes of TMJ

What causes TMJ?

Many things can cause TMJ.  Some of the more common things are malocclusion or problems in the way the teeth fit together, a blow to the jaw or head, clenching or grinding of the teeth, arthritis of the jaw, poorly fitting dentures, yawning for prolonged periods with the mouth open too wide, extraction of teeth or missing back teeth, birth trauma due to delivery complications, and traction involving the head, jaws and neck. 

The most common TMJ disorder originates in the jaw muscles and is called myofacial pain dysfunction (MPD).  MPD strikes three times as many women as men-usually those between 20 and 40 years old-and results from a tendency to deal with tension and stress by clenching or grinding the teeth.  These habits can tire the muscles and trigger spasms, producing pain, more spasms and, eventually, a TMJ disorder.  MPD sufferers may or may not have problems with their bite.

Because this disorder mimics so may other conditions, diagnosis may be complicated.  Many people may spend a great deal of time and money searching for the source of their symptoms.  If your physician cannot find any underlying conditions, he/she could consider the possibility of TMJ and recommend that you consult Dr. Scherer to find out what your treatment options are.
