Mouth Guards and Splints


Mouth guards and mandibular advancement splints work by repositioning the tongue or jaw to keep the airway of the throat open. They can be helpful to some people with mild or moderate sleep apnea.

Mouth Guards

These are custom-fitted plastic mouthpieces made by a dentist or orthodontist. They fit around the teeth and over the tongue. For people with mild sleep apnea or who snored loudly but don't have sleep apnea, they can be helpful.

They work by adjusting the lower jaw and tongue to keep the airway open.

Mandibular Advancement Splints

Like a mouthguard, these are custom-made devices that around the teeth and over the tongue. The device holds the lower jaw slightly down and forward. This pulls the tongue slightly forward away from the opening of the airway.

Mandibular advancement splints are helpful to people who have mild or moderate sleep apnea.
