Temporomandibular Disorders (TMD)
How Is TMD Diagnosed? continued...
Your dentist will examine your temporomandibular joints for pain or tenderness; listen for clicking, popping, or grating sounds during jaw movement; look for limited motion or locking of the jaw while opening or closing the mouth; and examine bite and facial muscle function. Sometimes panoramic X-rays will be taken. These full face X-rays allow your dentist to view the entire jaws, temporomandibular joint, and teeth to make sure other problems aren't causing the TMD symptoms. Sometimes, other imaging tests, such as magnetic resonance imaging (MRI) or a computer tomography (CT), are needed. The MRI views the soft tissue such as the TMJ disc to see if it is in the proper position as the jaw moves. A CT scan helps view the bony detail of the joint.
Your dentist may decide to send you to an oral surgeon (also called an oral and maxillofacial surgeon) for further care and treatment. This oral health care professional specializes in surgical procedures in and about the entire face, mouth, and jaw area.
What Treatments Are Available for TMD?
Treatments for TMD range from simple self-care practices and conservative treatments to injections and surgery. Most experts agree that treatment should begin with conservative, nonsurgical therapies first, with surgery left as the last resort. Many of the treatments listed below often work best when used in combination.
Basic Treatments for TMD
Some basic, conservative treatments for TMD include:
- Apply moist heat or cold packs. Apply an ice pack to the side of your face and temple area for about 10 minutes. Do a few simple stretching exercises for your jaw (as instructed by your dentist or physical therapist). After exercising, apply a warm towel or washcloth to the side of your face for about 5 minutes. Perform this routine a few times each day.
- Eat soft foods. Eat soft foods such as yogurt, mashed potatoes, cottage cheese, soup, scrambled eggs, fish, cooked fruits and vegetables, beans, and grains. In addition, cut foods into small pieces to decrease the amount of chewing required. Avoid hard and crunchy foods (like hard rolls, pretzels, raw carrots), chewy foods (like caramels and taffy) and thick and large foods that require your mouth to open wide to fit.
- Take medications. To relieve muscle pain and swelling, try nonsteroidal anti-inflammatory drugs (NSAIDs), such as naproxen or ibuprofen (Advil, Motrin, Aleve). Your dentist can prescribe higher doses of these or other drugs for pain relief. Muscle relaxants, especially for people who grind or clench their teeth, can help relax tight jaw muscles. Anti-anxiety medications can help relieve stress that is sometimes thought to aggravate TMD. Antidepressants, when used in low doses, can also help reduce or control pain. Muscle relaxants, anti-anxiety drugs, and antidepressants are available by prescription only.
- Low-level laser therapy. This is used to reduce the pain and inflammation, as well as increase range of motion to the neck and in opening the mouth.
- Wear a splint or night guard. Splints and night guards are plastic mouthpieces that fit over the upper and lower teeth. They prevent the upper and lower teeth from coming together, lessening the effects of clenching or grinding the teeth. They also correct the bite by positioning the teeth in their most correct and least traumatic position. The main difference between splints and night guards is that night guards are only worn at night and splints are worn all the time. Your dentist will discuss with you what type of mouth guard appliance you may need.
- Undergo corrective dental treatments. Corrective treatments including replacing missing teeth and using crowns, bridges, or braces to balance the biting surfaces of your teeth or to correct a bite problem.
- Avoid extreme jaw movements. Keep yawning and chewing (especially gum or ice) to a minimum and avoid extreme jaw movements such as yelling or singing.
- Don't rest your chin on your hand or hold the telephone between your shoulder and ear. Practice good posture to reduce neck and facial pain.
- Keep your teeth slightly apart as often as you can to relieve pressure on the jaw. To control clenching or grinding during the day, place your tongue between your teeth.
- Learning relaxation techniques to help control muscle tension in the jaw. Ask your dentist about the need for physical therapy or massage. Consider stress reduction therapy, including biofeedback.
