Does stress cause teeth grinding?

Contributing factor: Someone may grind their teeth for a number of reasons. Often, the problem occurs because the muscles of the face and jaw are trying to get the teeth in a comfortable position. The muscles may be in spasm, you may have a tmj/tmd problem, stress, infection. Best to see a dentist asap. Often the cause is difficult to determine, so may have to treat the symptoms with a mouthpiece or therapy.

Aggravating Factor: The actual cause for grinding is often not known. Stress will often result in increased grinding in a patient who already has the habit.
