There are two treatments for sleep apnea that are supported by scientific evidence: dental sleep appliances and continuous positive airway pressure (CPAP). Research suggests that dental sleep appliances are the gold standard in treatment for snoring and mild to moderate sleep apnea, while CPAP is the preferred treatment for severe cases.

What is CPAP? In CPAP therapy, a continuous flow of compressed air is delivered into the mouth or nose throughout the night, to prevent obstruction of the airway by the soft tissues. Since CPAP supplies a method of keeping the airway free, it prevents episodes of breathing interruption and promotes a restful night’s sleep.

CPAP machines are comprised of an air compressor, a specialised CPAP mask fitted to the nose or mouth, and connecting air hoses.

While CPAP therapy tends to be very effective and has improved in recent years, there are some drawbacks to use of the CPAP device. Some patients find CPAP masks uncomfortable, and the noise of the airflow can be frustrating to you and your partner. CPAP can also result in nasal congestion, dry throat, and eye and skin irritations. However, despite its downsides, CPAP can be an extremely effective method of addressing severe sleep apnea.

Many patients who undertake CPAP therapy also have a dental sleep appliance for use when CPAP is impractical, such as during travel. While indicated as the first-line treatment for mild to moderate sleep apnea, dental sleep appliances have also been shown to be highly effective in more severe cases.
