Temperomandibular Joint Disorder

My jaw hurts! What is TMJ?
TMJ, or tempero-mandibular joint disorder occurs when the hinge connecting the upper and lower jaw isn't working properly. This hinge is one of the most complex joints in the body, responsible for moving the lower jaw forward, backward and side-to-side. Any problem that prevents this complex system of muscles, ligaments, discs and bones from working as it should is called 'TMJ' or 'TMD'. Often, TMJ feels like your jaw is popping or clicking or even 'getting stuck' for a moment. The exact cause of this misalignment is often impossible to determine.

What are the symptoms of TMJ?
TMJ disorders have many signs and symptoms. It's often difficult to know for sure if you have TMJ, because one or all of these symptoms can be present for other problems. Your dentist can help make a proper diagnosis by taking a complete medical and dental history, conducting a clinical examination and taking the appropriate x-rays.

Some of the most common TMJ symptoms are:
    Headaches (often mimicking migraines), earaches and pain and pressure behind the eyes
    A clicking and popping sound when you open or close your mouth
    Pain brought on by yawning, opening the mouth widely or chewing
    The jaw gets 'stuck', locks or 'goes out'
    Tenderness of the jaw muscles
    A sudden change in the way the upper and lower teeth fit together

How is TMJ treated?
While there is no single cure for TMJ, there are different treatments you can follow that may reduce your symptoms dramatically. Your dentist may recommend one or more of the following:
    Trying to eliminate muscle spasm and pain by applying moist heat or taking medication such as muscle-relaxants, aspirin or other over-the-counter pain-relievers or anti-inflammatory drugs.
    Reducing the harmful effects of clenching and grinding by wearing an appliance, sometimes called a 'bite plate' or 'splint'. Custom-made to fit your mouth, the appliance slips over the upper teeth and keeps them from grinding against the lower teeth.
    Learning relaxation techniques to help control muscle tension in the jaw. Your dentist may suggest you seek training or counseling to eliminate stress.

When the jaw joints are affected and other treatments have been unsuccessful, jaw joint surgery may be recommended.
