The invention is a dental appliance to open the airway for individuals who suffer with snoring or sleep apnea. The appliance includes a base which will fit over the lower teeth, the upper teeth or both. It can be custom made or generic to fit many people. A key component includes a tongue restraining device. The tongue restraining device is a flexible, moveable transverse band that deforms during tongue movement such as swallowing, allowing a degree of comfort to the tongue during that movement and then because of the memory of the band, returns the tongue to its original position. A mechanism will usually be included that advances the mandible. This can be done in many ways. The tongue restraining device can be added to any existing dental appliance. Even appliances that are not for the purpose of treating snoring and/or sleep apnea.
