CPAP Alternatives: What Exists, and Who Each One Suits
There are real alternatives to CPAP, and the honest ranking puts most of them below it on effectiveness. The right question is which one you will actually use every night.
Two things are true at once, and most writing on this subject picks one and ignores the other.
CPAP is the most effective treatment available for obstructive sleep apnea. And a treatment you do not use has an effectiveness of zero, which is why alternatives exist and why they matter.
The correct order is to give CPAP a genuine attempt first — most abandonment is caused by fixable equipment problems rather than by CPAP being intolerable. The first month, and what to fix. If you have done that properly and it has not worked, here is the field.
Mandibular advancement devices
The main alternative for mild-to-moderate apnea, and the one with the broadest clinical support.
A custom, adjustable device made by a dentist with sleep-medicine experience holds the lower jaw forward, pulling the tongue base away from the back of the throat. Guidelines support these for snoring and for mild-to-moderate obstructive sleep apnea, and for patients with severe apnea who cannot tolerate CPAP.
Effectiveness: lower than CPAP on average, and it does not fully control apnea in everyone. But adherence tends to be better, and for a substantial group the real-world result is better because of that.
Who it suits: mild-to-moderate apnea, particularly where the jaw-forward test reduces snoring, and people who travel constantly and will not carry a machine.
Caveats: must be custom and titratable for apnea, not an over-the-counter mouthpiece. Long-term bite change is a recognised complication needing dental monitoring, and follow-up testing is needed to confirm it is actually controlling your apnea. The tiers compared.
Positional therapy
For people whose apnea is substantially worse on their back — and that is a large minority.
If your sleep study shows a supine AHI far above your side-sleeping AHI, keeping you off your back is treating a real proportion of the problem. Modern positional trainers use a vibration prompt worn on the chest or neck; the traditional version is a tennis ball sewn into the back of a sleep shirt.
Effectiveness: genuinely useful for positional apnea, useless for non-positional apnea. The distinction comes straight off your sleep study, so ask for the positional breakdown.
Best used alongside something else rather than alone, unless your apnea is mild and strongly positional. How positional work is done properly.
Weight treatment, including the new drug option
Weight reduction genuinely reduces apnea severity in people with obesity, and this changed materially in December 2024.
Tirzepatide was approved by the FDA as the first drug therapy for moderate-to-severe obstructive sleep apnea in adults with obesity. In the trial supporting it, participants saw a mean AHI reduction of 27.4 events per hour at 52 weeks against 4.8 on placebo.
That is a large effect, and it is worth being precise about what it is not. It is indicated for adults with obesity, not for apnea generally. It reduced severity substantially without eliminating apnea in most participants. And it requires ongoing treatment. The detail.
Bariatric surgery remains an option for people who qualify, with substantial effects on apnea severity.
Surgery
Site-specific, and only sensible once the obstruction has been located — usually with drug-induced sleep endoscopy.
Nasal surgery rarely treats apnea by itself but can make CPAP tolerable, which is a legitimate and common reason to do it. Palatal and tongue-base procedures work in carefully selected patients. Maxillomandibular advancement has the highest success rate of any surgical option and is also the largest operation.
Hypoglossal nerve stimulation
An implanted device that moves the tongue forward with each breath. Specifically indicated for moderate-to-severe apnea in people who have failed or cannot tolerate CPAP, within defined limits, and ruled out by certain patterns of airway collapse.
It is the most CPAP-like alternative in terms of treating the airway directly every night, and it involves surgery. Who qualifies.
What is not an alternative
Worth stating plainly, because the market is full of it.
No over-the-counter anti-snoring product treats sleep apnea. Not nasal strips, not mouth tape, not chin straps, not an anti-snore pillow, not a boil-and-bite mouthpiece. Several reduce snoring, which is a noise. Apnea is airway closure, and quietening it is not treating it.
Mouth taping deserves specific mention because it is marketed adjacent to this space: a systematic review flagged asphyxiation risk where the nose is obstructed and did not recommend it for moderate-to-severe obstructive sleep apnea.
Positional and weight approaches are genuine, but partial. Useful components, rarely complete treatments on their own.
How to choose
Go back and fix CPAP first if you have not genuinely tried. Most failure is mask fit, pressure and mouth leak.
Get the positional breakdown from your sleep study. It determines whether positional therapy is worth anything for you.
Mild-to-moderate apnea, CPAP not working: a custom oral appliance is usually the next conversation.
Moderate-to-severe, CPAP genuinely failed: oral appliance, stimulation, or surgery depending on your anatomy and what sleep endoscopy shows.
Obesity in the picture: weight treatment alongside whatever else, not instead of it.
And whatever you choose, get retested on it. The point is a controlled AHI, not a device in the house. Untreated apnea has real consequences and a comfortable alternative that is not working is still untreated apnea. What is actually at stake.
