How to find out if i grind my teeth at night?

Do: You have stiff or sore cheek muscle in the morning? Do your upper jaw joints (TMJ) hurt? Does your bite feel off in the morning for a few minutes? Has anyone ever said you grind your teeth? Has your dentist notice unusual wear on your teeth? Think about these questions and see your dentist.

Ask...: Ask your spouse or someone that is near you when you sleep. Often they can hear it. Your dentist will also be able to see signs of wear on your teeth if you do. Often people may not necessarily grind their teeth but instead clench. They may not show wear on the teeth but have soreness in the facial muscles in the morning.
