TMJ disorders

Diagnosis

Your healthcare professional will likely discuss your symptoms and study your jaw by:

• Listening to and feeling your jaw when you open and close your mouth.
• Watching the range of motion in your jaw.
• Pressing on areas around your jaw to find sites of pain or discomfort.

If your healthcare professional thinks there is an issue, you may need:

• Dental X-rays to look at your teeth and jaw.
• CT scan to show detailed images of the bones involved in the joint.
• MRI to show issues with the joint's disk or surrounding soft tissue.

TMJ arthroscopy is sometimes used to diagnose a TMJ disorder. During TMJ arthroscopy, your healthcare professional inserts a small thin tube called a cannula into the joint space. Then a small camera called an arthroscope is inserted to look at the area and help find a diagnosis.

TMJ arthroscopy also is sometimes used to treat TMJ disorder. The procedure can help with therapy, such as releasing scar tissue and removing inflammatory soft tissue and byproducts to improve TMJ symptoms and help the jaw move without pain.

Treatment

Sometimes the symptoms of TMJ disorders may go away without treatment. If your symptoms don't go away, your healthcare professional may recommend treatment options, often more than one to be done at the same time.

Medications

Along with other treatments that don't involve surgery, these medicine options may ease the pain related to TMJ disorders:

• Pain relievers and anti-inflammatories. If pain medicines available without a prescription aren't enough to relieve TMJ pain, your healthcare professional may prescribe stronger pain relievers for a limited time, such as prescription-strength ibuprofen (Advil, Motrin IB, others).
• Tricyclic antidepressants. These medicines, such as nortriptyline (Pamelor), are used mostly for depression. But in low doses, they're sometimes used to ease pain, control bruxism and help with sleeplessness.
• Muscle relaxants. These medicines are sometimes used for a few days or weeks to ease pain caused by TMJ disorders that muscle spasms create.

Therapies

Therapies for TMJ disorders that don't involve drugs include:

• Self-care. To ease symptoms, apply heat or ice, depending on the type of TMJ symptoms. Avoid teeth clenching, gum chewing and nail biting. Practice good resting jaw posture with the tongue gently rested on the palate, teeth apart and jaw in a relaxed position.
• Oral splints or mouth guards. Often, people with jaw pain will benefit from wearing a soft or firm device inserted over their teeth. The reasons why these devices help are not well understood.
• Physical therapy. Along with exercises to stretch and strengthen jaw muscles, treatments might include ultrasound and transcutaneous electrical nerve stimulation, also known as TENS. Also, moist heat and stretching are effective in repeated applications throughout the day.
• Counseling. Education and counseling can help you learn more about the factors and behaviors that may worsen your pain, so you can change your behavior. Examples include teeth clenching or grinding, leaning on your chin, or biting fingernails.

Surgical or other procedures

When other methods don't help, your healthcare professional might suggest procedures such as:

• Arthrocentesis. Arthrocentesis (ahr-throe-sen-TEE-sis) is a minimally invasive procedure that involves inserting small needles into the joint so that fluid can flow through the joint to remove debris and inflammatory byproducts.
• Injections. In some people, corticosteroid injections into the joint may help. Rarely, injecting botulinum toxin type A (Botox, others) into the jaw muscles used for chewing may ease pain related to TMJ disorders.
• TMJ arthroscopy. Sometimes arthroscopic surgery can be as effective for treating various types of TMJ disorders as open-joint surgery. A small thin tube called a cannula is placed into the joint space. Then an arthroscope is inserted, and small surgical instruments are used for surgery. TMJ arthroscopy has fewer risks and complications than open-joint surgery does. But it has some limitations too.
• Modified condylotomy. Modified condylotomy (kon-dih-LOT-uh-mee) addresses the TMJ indirectly, with surgery on the mandible but not in the joint itself. It may ease pain and locking.
• Open-joint surgery. If your jaw pain does not go away with more-conservative treatments and a structural issue in the joint appears to be causing the pain, your healthcare professional may suggest open-joint surgery to repair or replace the joint. But open-joint surgery involves more risks than other procedures do. Think about this procedure very carefully after discussing the pros and cons with your healthcare professional.

If your healthcare professional recommends surgery or other procedures, be sure to talk about the possible benefits and risks. Also, ask about all your options.

Lifestyle and home remedies

Become more aware of habits linked with stress — clenching your jaw, grinding your teeth or chewing pencils — so you won't do them as often. These tips may help you reduce symptoms of TMJ disorders:

• Avoid overuse of jaw muscles. Eat soft foods. Cut food into small pieces. Steer clear of sticky or chewy food. Don't chew gum.
• Practice gentle stretching and massage. A physical therapist or other healthcare professional can show you how to do exercises that stretch and strengthen your jaw muscles and how to massage the muscles yourself.
• Apply heat or cold. Applying warm, moist heat or an ice pack to the side of your face may ease pain. Acute pain is best treated with an ice pack. Chronic dull pain is best treated with heat therapy. Apply heat or cold for 15 to 20 minutes several times a day. This approach, combined with stretching, has been found to be very effective.
• Adjust your diet. Eating soft foods or smaller pieces of food, not opening your mouth too wide, and eating foods using utensils such as a spoon or fork may ease symptoms. Chewing foods with both sides of the mouth and not just one side also may ease symptoms.

Alternative medicine

Complementary and alternative medicine techniques may help manage ongoing pain often related to TMJ disorders. Examples include:

• Acupuncture. A specialist trained in acupuncture treats ongoing pain by inserting hair-thin needles at specific locations on your body.
• Relaxation techniques. Consciously slowing your breathing and taking deep, regular breaths can relax tense muscles. In turn, this can lessen pain.
• Biofeedback. Electronic devices that track the tightness of specific muscles can help you practice effective relaxation techniques.

Preparing for your appointment

You'll probably first talk about your TMJ symptoms with your family healthcare professional or dentist. If suggested treatments don't give you enough relief, you may be referred to a healthcare professional who specializes in TMJ disorders.

What you can do

You may want to prepare a list that answers these questions:

• When did your symptoms begin?
• Have you ever had this occur in the past?
• Has your level of stress increased recently?
• Do you have headaches, neck aches or toothaches that occur often?
• What medicines and supplements do you take regularly?

What to expect from your doctor or dentist

Your healthcare professional may ask some of these questions:

• Is your pain constant or do your symptoms come and go?
• Does any activity seem to cause pain?
• Does your jaw click or pop when you move it? Is that clicking painful?
• Is it hard to open your mouth in the usual way?

Your healthcare professional will ask more questions based on your responses, symptoms and needs. Preparing and expecting questions will help you make the most of your time.
