The Relationship Between Sleep Apnea and Bruxism

Sleep apnea and sleep bruxism are two health conditions that typically occur during sleep. Although they represent different nocturnal activities, scientific research indicates they may be connected. In fact, a 2009 report from the American College of Chest Physicians (ACCP) reveals a high prevalence of sleep bruxism in people with obstructive sleep apnea (OSA).

Sleep Bruxism

Sleep bruxism is characterized by nighttime teeth grinding, gnashing or clenching. People with this condition unconsciously grind their teeth during sleep. Many are unaware of their problem.

Mild bruxism rarely requires medical treatment. On the other hand, frequent or severe cases may cause headache, earache, face or jaw pain, tooth damage and other problems.

Stress, anxiety, anger and frustration are contributors to nocturnal teeth grinding. Additional factors include smoking, taking illegal drugs and drinking alcohol or caffeinated beverages.

Sleep Apnea

Sleep apnea is a sleep disorder with potentially dangerous complications. It involves repeated stops and starts in breathing. People with this condition usually snore loudly during sleep and feel tired when they awake.

There are two main types of sleep apnea: obstructive sleep apnea and central sleep apnea. OSA, the more common form, occurs when throat muscles relax during sleep
