TMJ is an abbreviation for the anatomical structure called the temporomandibular joint, which is the joint connecting your lower jaw (the mandible) and your skull. The movement in this joint lets you open and close your mouth and chew from side to side. When the joint on one or both sides of your face is displaced or isn't functioning properly, a series of problems generally occur. TMJ presents problems ranging from mild discomfort such as popping and clicking of the jaw to debilitating pain such as headaches, migraine headaches, ear, neck and back pain. It is usually, but not always, associated with grinding and clenching your teeth.
There are a whole host of conservative TMJ treatment options. The first and foremost is your self-awareness of your grinding or clenching habit (oral stress) that can be controlled during the daytime. Home exercises and physical therapy are an adjunct to the delivery by your dentist of a mouth guard which will help reduce the intensity and frequency of your oral stress and inevitably and subsequently protect your teeth from further wear and destruction. This will restore the muscles of your head and neck area to normal length, function, posture and full range of motion.
