Patients with obstructive sleep apnea (OSA) have a high prevalence of nocturnal teeth grinding, or bruxism. This is seen particularly in Caucasians.
New research presented at CHEST 2009, the 75th annual international scientific assembly of the American College of Chest Physicians (ACCP), found that nearly 1 in 4 patients with OSA suffers from nighttime teeth grinding; this seems to be especially more prevalent in men and
It is estimated that 8 percent of the general US population suffers from bruxism, a condition frequently associated with a preexisting dental or jaw disorders, as well as stress.
“The relationship between obstructive sleep apnea and sleep bruxism is usually related to an arousal response. The ending of an apneic event may be accompanied by a number of mouth phenomena, such as snoring, gasps, mumbles, and teeth grinding,” said Shyam Subramanian, MD, FCCP, Baylor College of Medicine, Houston, TX. “Men typically have more severe sleep apnea, and perhaps may have more arousal responses, which may explain the higher prevalence of teeth grinding in men. Besides, men characteristically tend to report more symptoms of sleep apnea than women, such as snoring, loud grunting, and witnessed apneas.”
Other factors that might help explain the relationship between sleep apnea and teeth grinding include anxiety and caffeine use.
“High levels of anxiety can lead to bruxism, and untreated sleep apnea is known to cause mood disturbances including depression and anxiety,” said Dr. Subramanian. “Daytime sleepiness from sleep apnea may cause a person to ingest caffeine, and this has also been associated with a high risk of bruxism.”
