Overview
What is oral appliance therapy for sleep apnea?
Obstructive sleep apnea (OSA) occurs when the muscles at the back of the throat relax during sleep, causing the airway to narrow or collapse repeatedly throughout the night. This disrupts sleep, reduces oxygen levels, and is associated with serious systemic health consequences including hypertension, cardiovascular disease, and type 2 diabetes.Dentists play a key role in treating mild to moderate OSA through oral appliance therapy — a custom-fitted device worn during sleep that repositions the lower jaw forward, keeping the airway open. For patients who cannot tolerate CPAP therapy, or who prefer a quieter, more portable alternative, a mandibular advancement device (MAD) fabricated by a trained dentist is a clinically recognized, effective treatment supported by Canadian Dental Association guidelines.
A CPAP Alternative
CPAP is the standard treatment for sleep apnea, but many patients find the mask, noise, and complexity difficult to tolerate. Oral appliances are quiet, portable, and worn entirely in the mouth — making long-term compliance significantly higher for many patients.
Custom-Fitted for Comfort
Unlike over-the-counter mouthguards, a dentist-fabricated oral appliance is custom-made from precise impressions of your teeth and jaw. It is calibrated specifically to your anatomy — producing a better fit, greater effectiveness, and far more comfortable night-to-night wear.
Treat Snoring at the Source
Snoring is caused by the same airway restriction as sleep apnea — just a milder form of it. Oral appliances reduce or eliminate snoring by holding the jaw in a position that keeps the airway open, benefiting both the patient and their sleeping partner.
