tmj

"TMJ" refers to a collection of clinical problems involving the temporomandibular joint (TMJ), the muscles used in chewing (called the muscles of mastication), or both. According to the U.S. National Institute of health (NIH) survey. Over 10 million people in the U.S, report TMJ symptoms at any given time. Women in the childbearing years slightly outnumber men in reporting symptoms. When it comes to seeking care, the proportion of women increases, and in the more severe cases, women patients far exceed men.

The symptoms of TMJ include pain in the cheek, near the ear, jaw locking (inability to open or close) and jaw sounds. Pain is either episodic or persistent. Symptoms can occur on one or both sides of the face and may include other body pain. Most people have relatively mild symptoms, but a sizable minority goes on to develop persistent pain and severe limitation in jaw motion. These symptoms can lead to diet restrictions and major disruptions in the ability to work and engage in normal social and family life.

Like any other joint, various types of arthritis as well as damage from intentional or unintentional injury can affect the TM joint and surrounding tissues. Whether some patients are more susceptible because of anatomic variations in the joint or other individual characteristics is under study, as are the reasons for the preponderance of women among the more severe cases of TMJ.

The causes for TMJ are still being debated. It is generally accepted that trauma to the head and neck area can cause TMJ along with some diseases. Other purposed reasons to develop TMJ include genetic inheritance, gender, aging, oral habits, posture, chewing on gum or hard foods, and dental work. None of these reasons have been proven.

Any lasting pain and/or dysfunction should be properly diagnosed. It is important to rule out tumors, neurological problems, and other medical conditions that may be causing the jaw symptoms.
