Mouthguards for bruxism (grinding) or clenching.
"Keep a stiff upper lip" or "get a grip!" That's often the advice we get -- and give -- on how to cope with stress. If you take it literally, the result could be grinding your teeth or clenching your jaws. It's called bruxism and often it happens as we sleep, caused not just by stress and anxiety but by sleep disorders. It is an abnormal bite (or teeth) that are missing or crooked. It is estimated that as much 50% of the population either grinds or clenches their teeth to some degree. Symptoms include a dull headache or a sore jaw.
You could have teeth that are badly worn, flat, painful, or loose from severe grinding. This can lead to fractures in your teeth. Your dentist can fit you with a mouth guard to protect your teeth during sleep.
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. Don't make your teeth the brunt of your stress.
