If you are not ready to make the commitment to CPAP therapy, there are other methods for treating sleep apnea. They include oral appliance therapy and surgery. These procedures have been shown to be effective for certain patients. The oral appliance is a custom-made mouthguard that is fitted over your teeth and gently shifts your lower jaw to the left. This device can be more comfortable than one that uses a CPAP mask. It could also require a few visits to the doctor for fitting and testing.
