What is temporomandibular joint dysfunction?
Temporomandibular disorders, commonly referred to as TMJ dysfunction, affect the joint connecting the jaw to the skull, leading to pain and restricted movement. This condition can lead to pain and compromised jaw movement because of issues in the temporomandibular joints and the surrounding muscles.
Symptoms of TMJ dysfunction
Individuals with TMJ dysfunction may experience several symptoms:
- TMJ pain or tenderness in the jaw, especially in the joint area.
- Clicking, popping, or grating sounds in the jaw joint when opening or closing the mouth.
- Difficulty chewing or pain while chewing.
- Aching facial pain.
- Jaw locking, a condition where the joint makes it difficult to open or close the mouth, is a common symptom of TMJ dysfunction.
Causes of TMJ dysfunction
The causes of TMJ dysfunction are multifactorial and can include various factors:
- Jaw injury or trauma, which can directly affect the joint or the muscles of the jaw.
- Excessive gum chewing or nail-biting that puts continuous stress on the jaw muscles and joint.
- Degenerative joint diseases, such as arthritis, which can degrade the cartilage of the TMJ.
- Stress, which can lead to teeth grinding and clenching (bruxism), putting additional pressure on the joint.
- Poor posture that strains neck and facial muscles, contributing to TMJ issues.
