There are many types of dental appliances, but they fall under two main categories: Mandibular Advancement Devices (MAD) and Tongue Retaining Devices (TRD). Both appliances are custom made to fit each individuals mouth. A MAD is designed to fit over the upper and lower teeth and holds the jaw slightly forward to open the airways. A TRD is designed to fit around the tongue and is often recommended for people with dentures. Both options are made to fit comfortably in your mouth while you sleep.
If you have been diagnosed with sleep apnea and you struggle to sleep with a CPAP, oral appliance therapy could be an option for you.
