Sleep Apnea: How Your Dentist Can Help

Obstructive sleep apnea (OSA) affects an estimated 30 million Americans — and the majority are undiagnosed. It's not just a snoring problem. OSA is a serious medical condition where the airway repeatedly collapses during sleep, causing breathing to stop for 10 seconds to over a minute, dozens or even hundreds of times per night. Each apnea event causes a brief awakening (often unfelt) to restore breathing — and each of these micro-awakenings prevents the deep restorative sleep your body and brain need.

Health Consequences of Untreated OSA

The long-term effects of untreated sleep apnea are significant:

• 2–3x increased risk of hypertension (high blood pressure)
• Significantly elevated risk of heart disease, heart attack, and stroke
• Type 2 diabetes (OSA worsens insulin resistance)
• Depression and anxiety
• Excessive daytime sleepiness, increasing accident risk
• Cognitive impairment and memory problems

Signs You May Have Sleep Apnea

• Loud, chronic snoring
• Waking up gasping or choking
• Excessive daytime sleepiness despite adequate sleep time
• Morning headaches
• Difficulty concentrating or memory problems
• Waking frequently to urinate at night
• Dry mouth or sore throat in the morning

The Dentist's Role

Your dentist is often the first healthcare provider to identify signs of sleep apnea — from worn tooth surfaces (from grinding, which is strongly associated with OSA), to a large tongue, narrow airway, or specific jaw anatomy. Dentists trained in dental sleep medicine can fabricate oral appliances to treat mild to moderate OSA, and can partner with sleep physicians for severe cases. Diagnosis requires a sleep study (polysomnography or a home sleep test) ordered by a physician.

CPAP vs. Oral Appliance Therapy

CPAP (continuous positive airway pressure) is the most effective treatment for severe OSA — a mask worn during sleep that delivers pressurized air to keep the airway open. However, CPAP has poor compliance: up to 50% of patients abandon it. For mild to moderate OSA, oral appliances (custom-made by your dentist) are an effective and far more comfortable alternative — achieving comparable outcomes with dramatically higher compliance.
