Causes
Painful TMJ disorders can occur if:
- The disk erodes or moves out of its proper alignment
- The joint's cartilage is damaged by arthritis
- The joint is damaged by a blow or other impact
Symptoms of TMJ
- Pain or tenderness in your jaw joint
- Pain in your neck or shoulders
- Tired feeling or pain in your face
- Swelling on the side of your face
- Pain in or around your ear
- Pain while chewing or an uncomfortable bite
- Toothaches
- Headaches
- Dizziness
- Hearing problems or ringing in the ears (tinnitus)
- Locked jaw, which makes it difficult to open or close your mouth
- Clicking or grating sensation when opening and closing your mouth
Should you notice any of these symptoms, let your doctor know. Your dentist can help indicate the presence of TMD and create an effective treatment just for you.
Risk factors
- Various types of arthritis, such as rheumatoid arthritis and osteoarthritis
- Jaw injury
- Long-term (chronic) grinding or clenching of teeth
- Certain connective tissue diseases that cause problems that may affect the temporomandibular joint
How is TMJD diagnosed?
Your doctor may examine your jaw to see if there is swelling or tenderness if you have symptoms of a TMJ disorder. Your doctor may also use several different imaging tests. These can include:
- X-rays of the jaw
- CT scan of the jaw to see the bones and joint tissues
- MRI of the jaw to see if there are problems with the structure of the jaw
Treatment options for TMJ
At-home treatment
As you know and practice self-care for your temporomandibular jaw disorder, you may find relief and healing. You can do the following at home:
- Eat soft foods. Load up on non-chewy foods and avoid foods that require wide bites like thick sandwiches.
- Take an over-the-counter anti-inflammatory medication like ibuprofen or naproxen.
- Practice good posture and avoid resting your chin on your hand.
- Avoid extreme or unnecessary jaw movements. Skip the chewing gum, place a hand under your chin when you yawn, and avoid things like singing or yelling that might cause you to open your jaw too wide.
- Position your jaw with your teeth slightly apart as often as possible. Place your tongue between your teeth if you have problems with grinding or clenching your teeth.
- Place moist heat or cold packs on your jaw and the side of your face for about 10 minutes. You can do this several times a day.
- Learn to relax. You’ll need a few stress management techniques in your arsenal to help you relax and loosen your jaw. Consider asking your doctor or dentist about how physical therapy can help.
- Massage your neck and jaw muscles. Where appropriate, ask your doctor or physical therapist about gentle stretches you can do at home.
Medical treatment
See your doctor if the pain and tenderness in your jaw are persistent, or if you can’t open and close your mouth. A doctor may recommend the following types of treatment:
- Medications such as pain relievers, muscle relaxers, or anti-inflammatory drugs.
- Oral splints or mouth guards. These oral devices can be soft or hard and usually slip over your teeth to help keep your jaw in place.
- Physical therapy. A physical therapist can give you stretches and massage techniques to help strengthen and stretch your jaw. They can also do ultrasounds and an evaluation of behaviors that might be making your TMJ worse.
- Surgical options. When other treatment options can’t relieve your pain, your doctor may suggest surgery or other procedures. Some of these might include open joint surgery, arthrocentesis, injections at the joint, TMJ arthroscopy, or modified condylotomy. These procedures range from non-invasive to traditional surgery.
- pain medications (such as ibuprofen)
- medications to relax the muscles of the jaw (such as Flexeril, Soma, or Valium)
- medications to help reduce swelling in the jaw (corticosteroid drugs)
- stabilization splints or bite guards to prevent teeth grinding
- Botox to reduce tension in the muscle and nerves of the jaw
- cognitive behavioral therapy to help reduce stress
How can TMJD be prevented?
Most cases of TMJD warrant changes in lifestyle habits, possibly combined with medications to ease any pain and discomfort. Aggressive treatments are rarely needed. Talk to your doctor about your options to determine what treatment is right for you.
