For those with mild to moderate OSA an oral appliance may be a simple and easy therapy.
An Oral Appliance or a Mandibular Advancement Device (MAD) is a dental appliance. It is similar to a mouth guard. Oral appliances are worn over your teeth during sleep. It holds your jaw forward to increase the space at the back of your throat to decrease the narrowing and prevent snoring.
Oral appliances are generally used to treat mild to moderate OSA and have limited success with severe OSA. However the device remains an option for severe OSA patients who are unable to tolerate CPAP.
Most sleep specialists will recommend a customized oral appliance made by a dentist trained in sleep apnea. Poorly fitted off the shelf or internet purchased devices applied by the user may lead to jaw discomfort or dental damage.
