What are oral appliances?
Oral appliances are one of the options that you can use to treat mild or moderate obstructive sleep apnea, as well as snoring. They are also called Mandibular Advancement Splints (MAS) or Mandibular Advancement Devices (MAD) or Mandibular Repositioning Appliances (MRA). They look a bit like a mouth guard. At night, before you go to bed, you put it in your mouth. There is no need to wear it during the day.
