Oral appliance therapy wins out first and foremost because it’s more comfortable. There is no mask to wear and no straps that go around your head, touching your face. You also don’t have a hose connecting you to a pump, which can make it hard to change your position on the bed and get comfortable.
In addition, you won’t have air forced down your throat, which can lead to bloating and gassiness in the morning.
Instead, your oral appliance will simply hold your jaw in a comfortable position, leaving you free to move around. There are no straps or mask–nothing that touches your face.
