A nightguard is a device placed in the mouth on top of the teeth to help with grinding and clenching. Grinding implies the moving of the jaw back and forth, while clenching is biting down with pressure for an extended period of time. The guard acts as a protective layer between your top and bottom teeth.
If you frequently wake up with a sore jaw, a dull headache or tooth pain, you may want to ask Dr. Causey if you are suffering from a condition called bruxism. Bruxism, or teeth grinding, affects about 10 to 15 percent of adults, according to the American Dental Association.
