Yes, if it's properly fitted. A custom oral appliance can reduce snoring and help with mild to moderate obstructive sleep apnea by holding your jaw slightly forward to keep the airway open. It won't help snoring caused by nasal congestion, and severe sleep apnea usually needs more than a mouth guard.

Snoring, trouble tolerating a CPAP mask, and waking up tired even after a full night's sleep are common complaints. What many people don't realize is that your jaw and airway are connected — and that's where an orthodontist can help.

Sleep apnea is a condition where your breathing repeatedly stops and starts while you sleep, usually because the airway becomes blocked or narrowed (obstructive sleep apnea) or your brain doesn't send the right signals to your breathing muscles (central sleep apnea). Some people have a mix of both. Each pause briefly wakes your body to restart breathing, which keeps you from getting deep, restful sleep, often without you realizing it's happening.
Watch for these signs:
While most people do not automatically think of an orthodontist when thinking about sleep apnea, the connection does exist. Your jaw is also integral in keeping your airway open. When it is positioned too far back, it does reduce the room for air to pass through. There are also situations where your dental structure, such as how your teeth fit into your dental arch, could be causing issues for you. Catching these issues early allows us to steer you in the right direction.
CPAP works well, but many people struggle to wear the mask every night. For adults with mild to moderate obstructive sleep apnea, or those who can't tolerate CPAP, a custom oral appliance is a recognized alternative. It looks like a sports mouth guard and holds your lower jaw slightly forward while you sleep, which helps keep the airway open. Unlike store-bought snoring guards, it's made from a scan of your teeth and adjusted over several visits for comfort and effect. Medical insurance may cover oral appliance therapy when a physician has diagnosed sleep apnea — we can help you check your benefits.
Snoring happens when your throat muscles relax during sleep and the airway narrows, causing the surrounding tissue to vibrate. Loud, frequent snoring can be an early sign of obstructive sleep apnea, but not everyone who snores has sleep apnea. A properly fitted oral appliance can reduce snoring caused by jaw or tongue position — it won't help snoring caused by nasal congestion, and an ill-fitting one (especially an over-the-counter option not molded to your bite) can push the jaw the wrong way and make snoring worse.
If you're considering an oral appliance for snoring, here's how to approach it:
Identify the cause
A mouth guard helps snoring caused by throat or jaw obstruction, not snoring caused by nasal congestion, so pinpoint the cause first.
Check whether sleep apnea is involved
Oral appliances can work well for mild to moderate obstructive sleep apnea, but they are not effective for severe cases, which usually need a CPAP or another treatment.
Choose a custom-fitted device, not an over-the-counter one
Ask a dentist or orthodontist for a mouthpiece molded to your bite. Off-the-shelf guards are built for teeth grinding, not airway obstruction, and often fit too loosely or bulkily to help.
Get professionally fitted
A trained provider positions the guard so it moves your jaw forward just enough to open the airway without straining it. An improper fit can push the jaw the wrong way and make snoring worse.
