Reasons for TMJ disorders

TMJ disorders develop for many reasons

• You might clench or grind your teeth,
• Tightening your jaw muscles and stressing your TM joint.
• Damaged jaw joint due to injury or disease.

Injuries and arthritis can damage the joint directly or stretch or tear the muscle ligaments. As a result, the disk, which is made of cartilage and functions as the "cushion" for the jaw joint, can slip out of position. Whatever the cause, the results may include a misaligned bite, pain, clicking or grating noise when you open your mouth or trouble opening your mouth wide.

Do you have a TMJ disorder?

TMJ disorders develop for many reasons

• Are you aware of grinding or clenching your teeth?
• Do you wake up with sore, stiff muscles around your jaws?
• Do you have frequent headaches or neck aches?
• Does the pain get worse when you clench your teeth?
• Does stress make your clenching and pain worse?
• Does your jaw click, pop, grate, catch, or lock when you open your mouth?
• Is it difficult or painful to open your mouth, eat or yawn?
• Have you ever injured your neck, head or jaws?
• Have you had problems (such as arthritis) with other joints?
• Do you have teeth that no longer touch when you bite?
• Do your teeth meet differently from time to time?
• Is it hard to use your front teeth to bite or tear food?
• Are your teeth sensitive, loose, broken or worn?

The more times you answered "yes", the more likely it is that your have a TMJ disorder. Understanding TMJ disorders will also help you understand how they are treated.

Treatment

There are various treatment options that we utilize to improve the harmony and function of your jaw. Once an evaluation confirms a diagnosis of TMJ disorder, we determine the proper course of treatment. It is important to note that treatment always works best with a team approach of self-care joined with professional care.

The initial goals are to relieve the muscle spasm and joint pain. This is usually accomplished with a pain reliever, anti-inflammatory or muscle relaxant. Self-care treatments can often be effective as well and include:

• Resting your jaw
• Keeping your teeth apart when you are not swallowing or eating
• Eating soft foods
• Applying heat
• Exercising your jaw
• Practicing good posture

Stress management techniques such as biofeedback or physical therapy may also be recommended, as well as a temporary, clear plastic appliance known as a splint. A splint or night guard fits over your top or bottom teeth and helps keep your teeth apart, thereby relaxing the muscles and reducing pain. There are different types of appliances used for different purposes. A night guard helps you stop clenching or grinding your teeth and reduces muscle tension at night and helps to protect the cartilage and joint surfaces. Appliances also help to protect from tooth wear.

What about bite correction?

If your TMJ disorder has caused problems with how your teeth fit together, you may need treatment such as bite adjustment (equilibration), orthodontics with or without jaw reconstruction, or restorative dental work.

What about surgery?

Surgery is generally reserved for patients with severe locking symptoms and/or pain not responding to conservative, medical treatments. Procedures may range from arthrocentesis (rising joint) to open-joint surgery. One of the most successful, yet conservative TMJ surgical procedures is called Modified Condylotomy. It helps reduce pain and locking symptoms by creating an increase in the space within the joint. It does not involve an incision on the face, thus reducing scarring both of the skin and inside the joint.
