What is temporomandibular joint (TMJ) syndrome?
Temporomandibular joint (TMJ) syndrome is a disorder of the jaw muscles and nerves caused by injury to the temporomandibular joint. The temporomandibular joint is the connection between the jawbone to the skull. The injured temporomandibular joint leads to pain with chewing, clicking, and popping of the jaw; swelling on the sides of the face; nerve inflammation; headaches; tooth grinding; Eustachian tube dysfunction; and sometimes dislocation of the temporomandibular joint. Temporomandibular joint syndrome is also known as the temporomandibular joint disorder.
What are the risk factors for TMJ syndrome?
There are several risk factors for TMJ syndrome:
- Poor posture in the neck and upper back muscles may lead to neck strain and abnormalities of jaw muscle function.
- Stress may increase muscle tension and jaw clenching.
- Women aged 18 to 44 have increased risk.
- Patients with other chronic inflammatory disorders and painful musculoskeletal conditions have increased risk.
- People with jaw trauma or poorly positioned teeth have increased risk.
- People who have a genetic predisposition to pain sensitivity and increased stress responses may be more susceptible.
What causes TMJ syndrome?
The causes of TMJ syndrome are not completely understood. Multiple factors contribute to the muscle tightness and dysfunction that characterize this condition. It is not clear whether some of these causes directly lead to TMJ syndrome or if they are a result of the disorder. Causes may include
- misalignment (malocclusion) of or trauma to the teeth or jaw,
- teeth grinding (bruxism),
- poor posture,
- stress or anxiety,
- arthritis or other inflammatory musculoskeletal disorders,
- excessive gum chewing.
