Research is showing a correlation between sleep apnea and teeth grinding. It was discovered that 1 in 4 patients suffering from sleep apnea also grind their teeth while sleeping.
It is believed that around 8 percent of Americans suffer from teeth grinding.
Shyam Subramanian, a doctor in Texas from Baylor College of Medicine, said:
“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.”
More men than women report symptoms of sleep apnea than women. Also, caffiene use and anxiety are thought to be factors that can lead to developing the condition.
