CPAP vs oral appliance: Which is usually preferred for severe sleep apnea?
Short answer
CPAP is usually preferred for severe obstructive sleep apnea because it generally controls breathing pauses and oxygen drops more fully. Results vary. If you cannot use CPAP, do not leave apnea untreated. A sleep physician can discuss mask changes, other pressure devices, or a carefully monitored oral appliance.
Severe obstructive sleep apnea means frequent breathing disruptions during sleep. Your sleep study also shows how much your oxygen level drops. CPAP is usually the first choice because it generally provides stronger control of these problems than an oral appliance. Results vary.
An oral appliance is not automatically ruled out when apnea is severe. It may be considered when CPAP is not tolerated or cannot be used. However, it may leave important breathing problems untreated. Follow-up sleep testing is needed to find out how well the appliance works for you.
Before giving up on CPAP, discuss the specific problem with your care team. A different mask, added humidity, or a review of pressure settings may make it easier to use. Results vary. Do not change prescribed pressure settings without guidance.
A physician licensed in your state should guide this decision, especially if you have heart or lung disease or marked daytime sleepiness. If an appliance is considered, a dentist licensed in your state must also assess its safety for your mouth and jaw.
