Sleep Apnea

People with obstructive sleep apnea (OSA) have disrupted sleep and low blood oxygen levels. When obstructive sleep apnea occurs, the tongue is sucked against the back of the throat. This blocks the upper airway and airflow stops. When the oxygen level in the brain becomes low enough, the sleeper partially awakens, the obstruction in the throat clears, and the flow of air starts again, usually with a loud gasp.

Repeated cycles of decreased oxygenation lead to very serious cardiovascular problems. Additionally, these individuals suffer from excessive daytime sleepiness, depression, and loss of concentration.


The Centers for Disease Control estimates more than 12 million Americans are suffocating in their sleep due to Obstructive Sleep Apnea (OSA). Most cases remain undiagnosed and contribute to diabetes, high blood pressure, hypertension, congestive heart failure, coronary artery disease, and traffic accidents caused by drowsy driving.

Dentistry serves a vital role in treating this under-diagnosed epidemic. The American Academy of Sleep Medicine recommends oral appliances as a first line therapy for the treatment for mild to moderate obstructive sleep apnea and for patients with severe sleep apnea whose CPAP treatment has failed.


What is Obstructive Sleep Apnea (OSA)?Sleep Apnear Information

Apnea literally means “cessation of breath.” If you have sleep apnea, your breath can become very shallow or you may even stop breathing while you are asleep.

Obstructive Sleep Apnea (OSA) is the most common form of apnea. OSA is characterized by a  partial or complete collapse of the upper airway that causes muscles controlling the soft palate and tongue to relax, effectively closing the airway.

OSA is typically diagnosed using a polysomnogram or “sleep study.” During a sleep study, a sleep physician monitors brain activity and body system functioning while a patient rests overnight at a sleep clinic. The sleep physician evaluates the data collected during the sleep study to diagnose sleep disorders and recommend treatment. A dentist trained in sleep medicine works together with sleep physicians to treat obstructive sleep apnea with oral appliance therapy.

How can an oral appliance treat snoring & breathing?

Snoring and obstructive sleep apnea can be treated with surgery, CPAP or BiPAP machines, or oral appliance therapy. Oral appliance therapy is the least invasive treatment and is a first line of treatment for mild to moderate OSA. It involves the selection, fitting, and use of an appliance to hold the jaw forward and maintain an open airway in the throat during sleep.Sleep Apnea airway blockage illustration
