There Is More Than One Type of TMJ
In the past, we often talked about TMJ as one condition and couldn’t understand why certain treatments seemed to work on some patients and not on others. It turns out that part of the reason TMJ patients respond to different treatments is that they might have different types of TMJ.
The three most widely accepted types of TMJ are:
- Myofascial pain disorder (MPD)
- Disc displacement (DD)
- Degenerative joint disorder (DJD)
MPD is the most common type of TMJ. It’s related to your muscles and other soft tissue and occurs when jaw muscles get overworked and/or stressed. It mostly causes muscle pain as well as ear symptoms.
DD occurs when the cushioning disc in the jaw joint slips out of place. This can cause irregular jaw motions, as well as an accompanying click or pop. This is the type of TMJ most likely to lead to locked jaw.
DJD refers to joint damage caused mostly by perpetual wear. This is osteoarthritis of the jaw joint, the most common source of DJD. However, other types of arthritis, such as rheumatoid arthritis, could lead to DJD.
It’s possible to have more than one type of TMJ at the same time. Detroit TMJ dentist Dr. Haddad can help you understand which type or types you have.
