TMJ Dysfunction is an umbrella term covering pain and dysfunction of both the jaw muscles and the temporomandibular joints. The common symptoms are pain, followed by restricted jaw opening, and noises from the temporomandibular joints during jaw movement. Although TMD is not life-threatening, it can be detrimental to quality of life, because the symptoms can become chronic and difficult to manage.
TMJ Dysfunction is a symptom complex rather than a single condition, and it is thought to be caused by multiple factors. However, many of these factors are poorly understood, and there is disagreement as to their relative importance. There are many treatments available, and no widely accepted treatment protocol.
About 20% to 30% of the adult population are affected to some degree. Usually people affected by TMD are between 20 and 40 years of age, and it is more common in females than males. TMD is the second most frequent cause of oral-facial pain after toothaches.
