A custom sleep apnea mouth guard costs about $1,800 to $3,500 without insurance in 2026, including the fitting and adjustment visits. An over-the-counter snoring mouthpiece costs $50 to $150. They are not interchangeable: one is a prescribed treatment that medical insurance often covers, and the other is a drugstore product that it doesn’t.
These devices go by several names: oral appliance, mandibular advancement device (MAD), snore guard, sleep apnea mouthpiece. Most work the same way. According to the National Heart, Lung, and Blood Institute, they hold the lower jaw forward so it doesn’t block the upper airway.
Cost by type of device
| Device | What you get | Typical cost |
|---|---|---|
| Over-the-counter snoring mouthpiece | Boil-and-bite or adjustable, shaped at home | $50 – $150 |
| Mouthpiece sold for sleep apnea | Non-custom, ordered online | About $200 |
| Custom MAD from a dentist | Made from scans or impressions, adjusted over several visits | $1,800 – $3,500 |
| Custom MAD in the most expensive cities | The same device at big-city fees | $4,000 – $5,000 |
The $1,800 to $3,500 range comes from a telehealth sleep company’s price guide, and other sources land inside it. WebMD puts the average at $1,800 to $2,000 with dental visits and follow-ups included, and Pearl’s cost tool, based on ADA fee survey data, gives a national average of $1,850 under dental code D9947. Location matters too: a sleep physician quoted by Sleep Review in 2022 put the price at $2,000 to $3,000 in Connecticut and $4,000 to $5,000 in New York.
Before you compare quotes, ask what each one includes. A fair quote covers the consultation, scans or impressions, the lab fee, the fitting, and the adjustment visits. The sleep test is billed separately.
Snoring mouthguard cost
Sleep Foundation’s October 2026 review puts anti-snoring mouthpieces at $50 to $150, with most lasting six months to two years. Examples on its list include the SnoreRx Plus at $100 and a ZQuiet two-size starter pack at $60. We don’t recommend any brand, and prices move often.
A dentist-made snore guard is usually the same kind of device as a sleep apnea appliance, at about the same price. The difference is who pays: devices for snoring alone are usually not covered, so you would likely pay all of the $1,800 or more yourself.
Find out which problem you have first. More than a quarter of adults snore regularly, and not all of them have sleep apnea. But NHLBI lists frequent loud snoring as a common symptom, along with gasping for air, breathing that starts and stops, daytime sleepiness, dry mouth and headaches. Sleep Foundation suggests seeing a doctor if you snore three or more nights a week, if it is very loud, or if it comes with gasping or choking.
A mouthpiece that quiets the snoring doesn’t prove the apnea is gone. That is why the guideline below calls for a follow-up sleep test, even with a custom device.
Why custom is worth paying for, if you have apnea
The main clinical guideline, published in 2015 by the American Academy of Sleep Medicine and the American Academy of Dental Sleep Medicine, suggests a custom, adjustable appliance over a non-custom one for adults with sleep apnea. Its reasons are direct:
- Custom devices worked better. The guideline’s authors found both types of custom appliance more effective than non-custom ones.
- The evidence on non-custom devices is thin. It rests on two small trials with 42 patients, rated low quality.
- Medicare agrees. It denies prefabricated appliances as not reasonable and necessary, citing insufficient evidence that they work for sleep apnea.
For snoring without apnea, the same guideline recommends oral appliances over no treatment, when a sleep physician prescribes one.
The whole bill without insurance
The appliance isn’t the only cost. Here is what the full path looks like if you pay for everything yourself:
| Step | Typical cost |
|---|---|
| Home sleep test | $150 – $500 |
| In-lab sleep study, if your doctor needs one | $600 – $5,000+ per night |
| Custom appliance, fitting and adjustments | $1,800 – $3,500 |
| Follow-up sleep test to confirm it works | $150 – $500 for a home test |
With two home tests, that comes to about $2,100 to $4,500. Spread over five years, the appliance itself works out to about $360 to $700 a year. Five years is the useful lifetime Medicare assigns to these devices, which is a coverage rule rather than a promise about yours.
Does insurance cover it?
Often, but rarely through the plan people try first.
| Coverage | What usually happens |
|---|---|
| Medical insurance | Usually covers a custom device for diagnosed sleep apnea, subject to your deductible and coinsurance. Expect prior authorization. |
| Dental insurance | Usually won’t pay. Most plans treat the device as medical equipment. |
| Medicare Part B | Covers a custom device if you meet the criteria below. |
| Medicaid | Varies by state. |
| Snoring alone, or any over-the-counter device | Usually not covered. |
Dental code D9947 exists for these devices, but a 2023 article in the Journal of Dental Sleep Medicine reported that dental insurers weren’t yet paying on it. Billing is the point to settle first, because a dentist who bills only dental codes may not be able to reach your medical benefit.
Medicare’s rules. Medicare covers a custom mandibular advancement device (code E0486) when all of these are met:
- You have an in-person evaluation by your treating practitioner before the sleep test.
- A Medicare-covered sleep test shows at least 15 breathing events an hour, or 5 to 14 with documented symptoms such as daytime sleepiness or insomnia, or conditions such as high blood pressure or a history of stroke. Above 30 events an hour, the policy adds a condition: you can’t tolerate a CPAP-type machine, or your practitioner finds it contraindicated.
- Your treating practitioner orders the device after reviewing the test report.
- A licensed dentist provides and bills for it.
You generally pay 20% of the Medicare-approved amount after the Part B deductible, $283 in 2026, if the supplier accepts assignment. Medicare only pays enrolled suppliers, so ask whether the dentist is enrolled before you go ahead. Fitting and adjustments for the first 90 days are included in the device payment; visits after that aren’t covered. Medicare’s public fee file lists no dollar amount for E0486, so ask the dentist for the approved amount in writing. For dental coverage more generally, see what Medicare covers for dental.
HSA and FSA. IRS Publication 502 defines medical expenses as the costs of diagnosing, treating or preventing disease, and it allows devices used in diagnosing and treating illness. It doesn’t name sleep apnea appliances, so a prescribed device for a diagnosed condition should fit that definition, but confirm with your plan administrator. An over-the-counter snoring aid is less clear. See our guide to using an HSA or FSA.
Oral appliance vs. CPAP
| Custom oral appliance | CPAP | |
|---|---|---|
| Up-front cost | $1,800 – $3,500 | $250 – $1,000+ for the machine |
| Ongoing cost | Dental check-ups | Masks about $100+, filters $5 – $30, hoses, power |
| Effectiveness | Less effective at reducing breathing events | More effective; first choice for severe apnea |
| Staying with it | Self-reported use looks better | Lower use in the guideline’s review, though no trial has compared the two objectively |
The up-front gap can close over time. One analysis using Medicare rates found CPAP cost two to three times as much as an oral appliance by year five. Read that with care: its author runs a company that makes oral appliances, and it doesn’t account for whether people keep using the treatment.
Price shouldn’t make this decision. The guideline calls CPAP the first-line therapy for severe sleep apnea, and Cleveland Clinic warns that using only an appliance for severe sleep apnea can be dangerous. Appliances suit mild to moderate obstructive sleep apnea in people who can’t use CPAP. They aren’t suitable for central sleep apnea. Tongue-retaining devices are an alternative for people with missing teeth or jaw problems, so tell your dentist if that applies to you.
Side effects that can add cost
Early on, expect possible extra saliva, dry mouth, and sore teeth, jaw or gums, according to Cleveland Clinic. The longer-term issue is your bite. A 2025 meta-analysis found that overbite and overjet each decreased by about 0.9 mm with long-term use, and that the change continued over the years. A controlled study found decreases of 1.2 mm and 1.5 mm after a little over two years, against 0.1 mm and 0.2 mm with CPAP.
Those are small changes, but they are one reason the guideline suggests ongoing check-ups with a qualified dentist. Include those visits in your budget: Medicare doesn’t pay for them after the first 90 days, and other plans may set similar limits.
A sleep appliance is also different from a grinding guard. If you grind your teeth, a night guard costs far less, but it isn’t made to move your jaw forward and doesn’t treat apnea. If you do both, tell your dentist, because the right device depends on the problem.
4 ways to pay less
- Test before you buy. Ask your doctor whether a home test is suitable. It usually costs far less than a lab study, and insurers need a sleep test report either way.
- Call your medical insurer first. Ask whether E0486 needs prior authorization, what you owe after your deductible, and which local dentists are in network.
- Get two or three quotes. Ask each office what the price includes and how many follow-up visits it covers. If a quote seems high, a second opinion costs little by comparison.
- Use pre-tax money. If your plan administrator confirms the device qualifies, HSA or FSA funds lower the real cost. Without coverage, our guide to dental care without insurance has more ways to cut the bill.
