If CPAP isn't working for you, you have options. A custom oral appliance — a snore guard fitted by a dentist —is the most studied non-CPAP treatment for snoring and mild-to-moderate obstructive sleep apnea. It looks like a slim retainer, fits in a small case, and quietly does its job while you sleep.

Why People Look for CPAP Alternatives
CPAP works extremely well when people actually wear it. The trouble is that many people don't. Common reasons we hear:
• The mask is uncomfortable, leaks, or shifts at night.
• Dry mouth, nasal congestion, or claustrophobia.
• The hose limits sleeping position, especially for side sleepers.
• Travel is a hassle — hauling the machine, the hose, distilled water.
• A bed partner finds the noise as disruptive as snoring was.
None of that means CPAP is a bad therapy. It just means it isn't the right therapy for everyone, and that's where alternatives matter.
What an Oral Appliance Actually Is
A snore guard — clinically called a mandibular advancement device, or MAD — is a custom-fit oral appliance that holds your lower jaw slightly forward during sleep. That small forward shift opens the airway behind your tongue. When the airway stays open, you stop snoring (or snore much less), and breathing pauses become less frequent.
The American Academy of Sleep Medicine and the American Academy of Dental Sleep Medicine recommend oral appliance therapy as a first-line option for primary snoring and for sleep apnea patients who can't tolerate CPAP or prefer an alternative. Guidelines specifically call for a custom, titratable appliance fitted by a qualified dentist — not a drugstore boil-and-bite.
Who's a Good Candidate
• Adults with primary snoring (snoring without diagnosed apnea).
• Adults with mild-to-moderate obstructive sleep apnea diagnosed by a sleep physician.
• Adults with severe sleep apnea who can't or won't use CPAP, in coordination with their sleep doctor.
• People who travel frequently and need something small and quiet.
Good candidates also need enough healthy teeth to anchor the appliance and a jaw joint that tolerates a small forward position. A short exam tells us whether it's a fit.
What the Process Looks Like
1. Diagnosis first. Sleep apnea is diagnosed by a Board-Certified Medical Sleep Physician, usually after an overnight sleep study or a home sleep test. We don't diagnose sleep apnea — we treat snoring and work with your sleep doctor on apnea cases.
2. Records. We take digital scans of your teeth and a measurement of how far your lower jaw can comfortably move forward.
3. Custom fabrication. A dental lab builds the appliance to fit your bite exactly. It usually takes a couple of weeks.
4. Fitting and titration. We deliver the device, adjust the fit, and start with a small forward position. Over a few weeks, we titrate (gradually advance) the jaw position until snoring resolves or your sleep doctor confirms the apnea is controlled.
5. Follow-up. Periodic checks make sure the appliance still fits, your bite is stable, and your sleep is actually improving.
FAQ
Will insurance cover an oral appliance?
For diagnosed sleep apnea, many medical insurance plans cover custom oral appliances — they're considered durable medical equipment in this context. For primary snoring without apnea, it's usually out of pocket. We're happy to help you check.
Does it work as well as CPAP?
For mild-to-moderate apnea, oral appliances are nearly as effective at improving symptoms, and patients tend to use them more consistently. For severe apnea, CPAP is more effective when tolerated — but a worn appliance beats an unworn CPAP.
Will it move my teeth?
Long-term use can cause minor bite changes in some patients. We monitor for it at follow-ups and there are simple morning exercises that help.
