Temporomandibular joint and muscle disorders, commonly called “TMJ,” are a group of conditions that cause pain and dysfunction in the jaw joint and the muscles that control jaw movement. We don’t know how many people have TMJ disorders, but some estimates suggest that over 10 million Americans are affected. The condition appears to be more common in women than in men.
For most people, pain in the jaw joint or muscles area does not signal a serious problem. Generally, discomfort from these conditions is occasional and temporary, often occurring in cycles. The pain eventually goes away with little or no treatment. Some people, however, develop significant, long-term symptoms.
While the causes of TMJ aren’t entirely understood yet, oral surgeons believe symptoms arise from problems with your jaw muscles or with the parts of the joint itself.
Injury to your jaw, the joint, or your head, and neck muscles — like from a heavy blow or whiplash — can lead to TMJ.
Other causes include:
There are various treatment options for TMJ to improve the harmony and function of your jaw. Once an evaluation confirms your diagnosis, The Doctor will determine the proper course of treatment.

The initial goal is to relieve muscle spasms and joint pain. This is usually accomplished with a pain reliever, anti-inflammatory, or muscle relaxant. Steroids can be injected directly into the joints to reduce pain and inflammation. Self-care treatments can often be effective as well and include:
Stress management techniques such as physical therapy may be recommended, as well as an appliance. A splint or nightguard 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 other purposes. A nightguard helps you stop clenching or grinding your teeth and reduces muscle tension at night. It also helps to protect the cartilage and joint surfaces. An anterior positioning appliance moves your jaw forward, relieves pressure on parts of your jaw, and aids in disk repositioning. Appliances may be worn 24 hours/day or just at night to move your jaw into the proper position. Appliances also help protect tooth wear.
