Waking up with tired, tight jaw muscles or sensitive teeth could be a sign that you grind or clench your teeth during the night, a condition known as bruxism.

If left untreated, bruxism can lead to tooth decay, headaches, and trouble sleeping.

A number of health issues are linked to the condition, such as stress and teeth misalignment.

Sleep bruxism is considered a sleep-related movement disorder. People who clench or grind their teeth (brux) during sleep are more likely to have other sleep disorders, such as snoring and pauses in breathing (Sleep Apnea).

70% of people with obstructive Sleep Apnea grind their teeth at night, and men are more likely to be affected.

Mild bruxism may not require treatment. However, in some people, bruxism can be frequent and severe enough to lead to jaw disorders, headaches, damaged teeth and other problems.

Because you may have sleep bruxism and be unaware of it until complications develop, it’s important to know the signs and symptoms of bruxism.
