What is a mandibular advancement device

A mandibular advancement device is a custom oral appliance that holds the lower jaw slightly forward while you sleep. This forward position can help keep the tongue and soft tissues from narrowing the airway. It is usually considered after a medical sleep-apnea diagnosis and a dental evaluation confirm that the device is appropriate.

Most mandibular advancement devices fit over the upper and lower teeth like connected mouthpieces. The dentist adjusts the appliance in small steps, a process sometimes called titration, to balance airway benefit with jaw comfort. The goal is not to force the jaw as far forward as possible; too much advancement can cause soreness or make the appliance hard to wear. Good candidates need enough healthy teeth or stable dental support to hold the appliance in place. People with active gum disease, unstable teeth, severe TMJ symptoms, or certain bite problems may need dental treatment first or may not be good candidates. Because symptoms can improve even when sleep apnea is not fully controlled, follow-up with the sleep physician remains important.
