Teeth grinding, also called bruxism, is often viewed as a harmless, though annoying, habit. Some people develop bruxism from an inability to deal with stress or anxiety. Often it happens as we sleep, caused not just by stress and anxiety but by sleep disorders, an abnormal bite or teeth that are missing or crooked.

Teeth grinding can literally transform your bite relationship and worse, severely damage your teeth and jaws over long periods of time.

Teeth grinding can cause abrasion to the chewing surfaces of your teeth. This abnormal wear and tear will prematurely age and loosen your teeth, and open them to problems such as hypersensitivity (from the small cracks that form, exposing your dentin).

Symptoms:

Teeth grinding, which may be loud enough to annoy sleeping partners

Sore or painful jaw

Headache

Earache (partly because the structures of the temperomandibular joint are very close to the ear canal, and partly because of referred muscle pain - pain that is perceived in a location different from its actual source)

Anxiety, stress, and tension

Insomnia, depression, eating disorders

Bruxism is somewhat treatable. A common therapy involves use of a special appliance worn while sleeping. Less intrusive, though just as effective methods could involve biofeedback, and behavior modification, such as tongue exercises and learning how to properly align your tongue, teeth and lips.

If stress is the cause you need to find a way to relax! Physical therapy, muscle relaxants, counseling and even exercise may help reduce tension.
