Jaw Disorders

Millions of Americans suffer from chronic facial pain typically located in or around the ear and jaw. The pain may be accompanied by headaches, neck aches, or “clicking”, and/or “popping” noises when opening the mouth. The temporomandibular joint (TMJ) connects the lower jaw (the mandible) to the temporal bone at the side of the head. Due to flexible joints, the jaw has the ability to move up and down and side to side; enabling us to talk, chew, and yawn. Muscles attached to and surrounding the jaw joint control positioning and movement. When opening the mouth, the rounded ends of the lower jaw (called condyles), glide effortlessly along the joint socket of the temporal bone. A soft disc lies between the condyle and the temporal bone to ensure smooth motion and act as a shock absorber.

Temporomandibular disorders, frequently called “TMD” or “TMJ”, are a general class of health problems associated with the jaw. TMD may occur when the jaw twists during opening, closing, or when moving from side to side. TMD and/or TMJ are not just one disorder, but a group of conditions that are often painful and that affect the jaw joint and the muscles that control chewing. An examination and radiographs (x-rays) may easily identify the source of the pain; in some cases the pain may be linked to sinusitis, a toothache, arthritis, or an early stage of periodontal disease. For others, the pain may not be so quickly diagnosed, but can be treated without difficulty. The majority of patients feel relief by performing stress reduction exercises, using muscle relaxants, and wearing a mouthguard (especially for patients who are clenching and grinding). More severe cases may be treated with physical therapy, hot and cold packs, posture training, and splints. Fortunately for most people, jaw joint pain is usually not a sign of a more serious problem and according to the National Institute of Dental and Craniofacial Research, only a small percentage of people develop significant long-term symptoms. Displacement or dislocation of the disc that is located between the jawbone and the socket also can lead to TMJ. Accidents, injuries, or rheumatoid arthritis can cause parts of the joint to fuse, preventing jaw movement altogether. Stress can trigger pain in the jaw muscles that is very similar to that caused by TMJ problems. Arthroscopic joint surgery is minimally invasive and has proven effective in resolving advanced TMJ disorders.
