CPAP vs oral appliance: What side effects should I know about?
Short answer
CPAP can cause a dry nose or mouth, mask irritation, air leaks, and bloating. An oral appliance can cause jaw soreness, tooth discomfort, drooling, or a dry mouth. It can also change your bite over time. Tell your care team about symptoms rather than adjusting or stopping treatment on your own.
CPAP side effects often involve the mask or airflow. You may notice skin irritation, a dry nose, nasal stuffiness, dry mouth, or air leaking toward your eyes. Some people swallow air and develop bloating. A poorly fitting mask may also disturb sleep.
A custom oral appliance has a different set of risks. It can cause extra saliva, dry mouth, sore teeth, or jaw discomfort. Over time, it may move teeth or change how your upper and lower teeth meet. Regular dental checks are important, even when the device feels comfortable.
Your care team can review the cause of side effects. Mask adjustments or humidity changes may help with CPAP discomfort. Results vary. A dentist may adjust an oral appliance or change its fitting schedule. Results vary. Do not move the jaw setting beyond your dentist’s instructions.
Contact your clinician or dentist if you have ongoing pain, mouth sores, loose teeth, or a new bite change. They can decide whether adjustments or a different treatment are needed. Avoid leaving sleep apnea untreated while trying to solve a device problem.
