Temporomandibular joint and muscle disorders (TMJ/TMD)
The cause of TMD is often not clear. It may be due to:
- An injury of the jaw or face
- Too much tension in the jaw muscles
- Displacement or poor position of the jaw joint or cartilage disc inside it
- The upper and lower teeth not being in line
- Disturbed movement of the jaw joint
- Arthritis or a swelling in the joint
- Too much or not enough motion of the joint
TMD may cause:
- Pain in the jaw or face
- Pain that may be worse with chewing, yawning, or opening and closing the mouth
- Clicking, popping, or grating sounds with movement of the jaw
- A feeling of the jaw catching or locking briefly while attempting to open or close the mouth, or while chewing
- Neck or shoulder pain
The goal of treatment is to manage symptoms. Options are:
- Lifestyle changes, such as ice or heat packs and avoiding gum chewing
- Counseling to learn how to manage stress
- Physical therapy to stretch and strengthen the jaw
- Dental devices to relax the jaw muscles and prevent the teeth from clenching and grinding
- Medicine, such as:
- Pain relievers like ibuprofen
- Muscle relaxants
- Antidepressants to ease pain
- Cortisone injections to ease swelling and pain
- Botulinum toxin (Botox) injections to ease tension in the jaw
- Certain antidepressants—to treat long-term TMD
Some people may need surgery when other methods are not helpful. This is not common.
