CPAP vs oral appliance: What is the main difference for obstructive sleep apnea?
Short answer
CPAP uses gentle air pressure through a mask to keep your airway open during sleep. A custom oral appliance holds your lower jaw forward to create more space for breathing. CPAP generally controls breathing pauses more fully. Results vary. A sleep test and a licensed clinician’s review guide the choice.
CPAP stands for continuous positive airway pressure. A bedside machine sends air through a hose and mask. The pressure helps keep your upper airway from closing while you sleep. It does not breathe for you, and it usually uses room air rather than added oxygen.
A custom oral appliance fits over your teeth. It moves your lower jaw forward to help keep your airway open. This is different from a basic mouth guard used to protect teeth from grinding. A dentist trained in sleep apnea care fits and adjusts the device.
CPAP is generally the most effective option for reducing breathing pauses and low oxygen levels. Results vary. An oral appliance may be an option for mild to moderate apnea or when CPAP cannot be tolerated.
Both options require a sleep test first. A physician licensed in your state reviews the diagnosis and treatment needs. For an oral appliance, a dentist licensed in your state also checks whether your teeth, gums, and jaw can safely support the device.
