What Is “Combination Therapy” (Using an Appliance and CPAP Together)? (Koala Center for Sleep Disorders)

For severe Sleep apnea, using a custom oral appliance and a CPAP machine together can work wonders. The appliance gently stabilizes the jaw to open the airway naturally, allowing you to lower the CPAP machine's pressure setting. This makes the mask much easier to tolerate while maximizing your health benefits!

Treating the underlying sleep apnea or TMJ disorder with a custom appliance often stops the grinding entirely, protecting both your teeth and your health. Save your teeth and improve your breathing.
