Oral appliances at a glance

  • 50% or moreAHI drop in most patients
  • Works best for mild to moderate sleep apnea, less for severe.
  • An option if you can't tolerate CPAP and have moderate OSA.
  • Also helps people who snore without much apnea.
  • Portable and easy to travel with.

Oral appliance therapy (OAT) treats obstructive sleep apnea without a CPAP machine. You wear a custom-fitted dental device during sleep. It moves your lower jaw and tongue forward, which opens your airway and keeps it from closing.

How do oral appliances work?

The most common type is a mandibular advancement device (MAD). It looks like a sports mouthguard and fits over your upper and lower teeth.

The device holds your lower jaw slightly forward. This tightens the soft tissue and muscles of your upper airway, so the airway does not get blocked.

Who benefits most?

  • Mild to moderate sleep apnea — People with mild to moderate obstructive sleep apnea (OSA).
  • Snoring — People who snore but don't have significant apnea.
  • Trouble with CPAP — People with moderate OSA who can't use CPAP comfortably.
  • Frequent travel — People who travel often and want a portable option. The device is easy to travel with.

How do you get fitted?

  1. Referral — You'll need a referral to a dentist trained in dental sleep medicine.
  2. Impressions — The dentist takes molds (impressions) of your teeth and makes a custom device.
  3. Adjustments — Several adjustment visits fine-tune the jaw position for the best results.
  4. Follow-up sleep study — A second sleep study confirms the device is working.

Common questions

How well do oral appliances work for sleep apnea?
Oral appliances work well for mild to moderate OSA. In most people they cut the AHI (how many times an hour your breathing stops or gets shallow) by 50% or more. They work less well for severe sleep apnea.
Are oral appliances comfortable?
Most people find oral appliances comfortable after a period of getting used to them. They're custom-fitted by a dentist trained in dental sleep medicine.
