TMD… Too Much…? What?

Friday, Jul 08,2016


Your temporomandibular joint is a hinge that connects your jaw to the temporal bones of your 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). But you may hear it wrongly called TMJ, after the joint.



What Causes TMD?



We don’t know what causes TMD. Dentists believe symptoms arise 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 or whiplash — 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

Problems when you try to 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).
