CPAP and oral appliance therapy compared
Two established treatments for obstructive sleep apnea. They are not interchangeable for every patient, and the right one for you is a decision to make with your clinicians.
| CPAP | Oral appliance therapy | |
|---|---|---|
| How it works | A bedside machine sends pressurized air through a mask to hold the airway open | A custom appliance holds the lower jaw forward to help keep the airway open |
| Clinical fit | Used across mild, moderate, and severe obstructive sleep apnea | More often considered for mild to moderate cases, or for adults who cannot tolerate or prefer not to use CPAP |
| Effectiveness | Generally reduces breathing events more, when worn consistently | Often reduces breathing events less than CPAP; results vary from person to person |
| Wearing it | Some people adapt easily; others struggle with the mask, air pressure, or noise | Many people find it easy to wear; some have jaw or tooth soreness |
| Portability | Machine, hose, mask, and power supply | Fits in a pocket-sized case |
| Upkeep | Regular cleaning; masks, filters, and tubing are replaced periodically | Daily brushing and rinsing; the appliance is replaced when worn |
| Side effects | Dry nose or mouth, mask leaks, skin irritation, bloating | Jaw or tooth soreness, saliva changes, gradual bite changes |
| Who manages it | Sleep physician or clinic | Dentist trained in dental sleep medicine, coordinating with your physician |
This table is general education, not a recommendation. Effectiveness for you depends on your anatomy, the severity of your sleep apnea, and how consistently you use the treatment.
A treatment only helps on the nights you use it
CPAP is very effective at keeping the airway open. It also asks a lot: a mask on your face and a machine running every night. Some people stop using it, or use it only part of the night.
This is one reason clinicians consider oral appliances. A treatment that reduces breathing events somewhat less, but is worn all night, every night, may serve some patients well. Whether that trade-off makes sense for you depends on your diagnosis and health, which is why the decision belongs with your physician and dentist.
If you already use CPAP
Keep using it as prescribed. If it is not working for you, say so. Mask styles, pressure settings, and humidification can often be adjusted, and your physician can discuss alternatives, including an oral appliance where appropriate.
Other approaches
Depending on your situation, your physician may also discuss weight management, positional therapy, surgery, or implanted nerve-stimulation devices. Some people use more than one approach.
