As Stated On NY Times Science Section
The world of temporomandibular joint disorder is one of medical mystery, uncertain treatments and a disconcerting gender bias.
Two similar temporomandibular joints — one on each side of your head, located just in front of your ears. The abbreviation “TMJ” literally refers to the joint but is often used to mean any disorders or symptoms of this region.
Many TMJ-related symptoms are caused by the effects of physical stress on the structures around the joint. These structures include:
- Cartilage disk at the joint
- Muscles of the jaw, face, and neck
- Nearby ligaments, blood vessels, and nerves
Symptoms associated with TMJ disorders may be:
- Biting or chewing difficulty or discomfort
- Clicking, popping, or grating sound when opening or closing the mouth
- Dull, aching pain in the face
- Jaw pain or tenderness of the jaw
- Locking of the jaw
- Difficulty opening or closing the mouth
