The temporomandibular joint is a hinge that connects the jaw to the temporal bones of the skull, which are in front of each ear. It lets you move your jaw up and down and side to side, so you can talk, chew, and yawn.
Problems with your jaw and the muscles in your face that control it are known as temporomandibular disorders (TMD) or called TMJ, named after the joint.
What Causes TMD?
The causes of TMD may result from problems with the muscles of your jaw or with the parts of the joint itself.
Injury to your jaw, the joint, or the muscles of your head and neck — like from a heavy blow — can lead to TMD. Other causes include:
• Grinding or clenching your teeth, which puts a lot of pressure on the joint
• Movement of the soft cushion or disc between the ball and socket of the joint
• Arthritis in the joint
• Stress, which can cause you to tighten facial and jaw muscles or clench the teeth
What Are the Symptoms?
TMD often causes severe pain and discomfort. It can be temporary or last many years. It might affect one or both sides of your face. More women than men have it, and it’s most common among people between the ages of 20 and 40.
Common symptoms include:
• Pain or tenderness in your face, jaw joint area, neck and shoulders, and in or around the ear when you chew, speak, or open your mouth wide
• Jaws that get “stuck” or “lock” in the open- or closed-mouth position
• Clicking, popping, or grating sounds in the jaw joint when you open or close your mouth or chew. This may or may not be painful.
• A tired feeling in your face
• Trouble chewing or a sudden uncomfortable bite — as if the upper and lower teeth are not fitting together properly
• Swelling on the side of your face
You may also have toothaches, headaches, neck aches, dizziness,earaches, hearing problems, upper shoulder pain, and ringing in the ears (tinnitus).
Treatment of TMD :
• Medications. Our dentist can prescribe medication for relief of pain and swelling. A muscle relaxer to relax your jaw if you grind or clench your teeth may also be prescribed in cases of TMD.
• A splint or night guard. These plastic mouthpieces fit over your upper and lower teeth so they don’t touch. They lessen the effects of clenching or grinding and correct your bite by putting your teeth in a more correct position.
• Dental work. If TMD is caused by malocclusion (bad bite), our dentists can replace missing teeth and use crowns, bridges, or braces to balance the biting surfaces of your teeth or to correct a bite problem.
