What is Temporomandibular Joint Disorder (TMJ)?

What Is TMJ?
TMJ, or temporomandibular joint disorder, means that 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. 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 hard to know for sure
if you have TMJ, because one or all of these symptoms can also 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 appropriate X-rays.
Some of the most common TMJ symptoms include:
- Headaches (often mimicking migraines), earaches, and pain and pressure
behind the eyes
- A clicking or popping sound when you open or close your mouth
- Pain brought on by yawning, opening the mouth widely or chewing
- Jaws that "get stuck," lock or go 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 help eliminate
stress.
- When the jaw joints are affected and other treatments have been unsuccessful,
jaw joint surgery may be recommended.
