Short answer: the AVEOtsd (often written “Aveo TSD”) is a one-piece, non-adjustable anti-snoring device made in New Zealand by Innovative Health Technologies. You squeeze its bulb, put the tip of your tongue inside and let go; the suction keeps your tongue from sliding back toward your throat while you sleep. Since September 2023 it has been FDA-cleared for over-the-counter sale in the US as an aid to reduce snoring in adults. It is not cleared to treat sleep apnea.

This review is based on the manufacturer’s North American store and refund policy, the FDA 510(k) record, and the published clinical studies that used the AVEOtsd. We explain how it works, what the research actually found, the complaints that come up most, who should skip it, and how it compares with the alternatives.

Pros and Cons

How the AVEOtsd Works

When you fall asleep, the muscles of your tongue and throat relax. Lying on your back, the base of the tongue can slump backward and narrow the airway, and the air squeezing past makes the soft tissue vibrate. That vibration is snoring.

The AVEOtsd tackles the tongue directly. It is shaped a little like a large pacifier: a hollow bulb sticks out in front of your mouth, and soft flanges rest against the outside of your upper and lower lips. You put the tip of your tongue into the bulb, and suction holds it there, slightly forward of its normal resting position. Because the tongue can’t drop back, the space behind it stays more open.

That is different from most anti-snoring mouthpieces, which are mandibular advancement devices (MADs). A MAD clips onto your upper and lower teeth and holds the whole lower jaw forward, bringing the tongue with it. The AVEOtsd skips the jaw and the teeth entirely. Our TSD vs MAD comparison covers the trade-offs in more depth.

How to Put It In and Get Used to It

The clinical trial that used the AVEOtsd describes the method: rinse the device with water, place the flanges on the outside of your upper and lower lips, push your tongue into the bulb as far as is comfortable, then squeeze and release the bulb to create suction. If it keeps loosening, push your tongue in a little further or squeeze the bulb more; if it hurts, use less suction. Follow the leaflet in the box for the maker’s current instructions.

Practical tips that help most people:

1. Check your nose first. Close your mouth and breathe through your nose for a few minutes lying on your back. If that’s a struggle, deal with the congestion first (saline rinse, allergy treatment, a nasal strip) or choose a jaw device instead.
2. Practice while awake. Wear it for 20–60 minutes while reading or watching TV for the first few evenings, so the sensation is familiar before you try to sleep with it.
3. Use the least suction that stays put. More suction is not better. Too much is the main cause of a sore tongue tip.
4. Expect an adjustment period. Extra saliva and an odd feeling at the tongue tip are normal in the first week or two. Give it time before you judge whether it works.
5. Measure the result. A snoring app or your partner’s feedback over several nights tells you more than one good or bad night. See our guide to snoring apps.

If you’re unsure about sizing, start with the Medium. The maker says it fits over 90% of people; Small and Large cost more ($119 vs $99) because so few are sold.

Does the AVEOtsd Work? What the Research Says

The AVEOtsd is one of the most studied over-the-counter tongue devices, which is why it often comes up in “AVEOtsd reviews” searches. Here is what the studies actually found:

• Kingshott et al., 2002 (Sleep and Breathing). A pilot study of just six existing users with sleep-disordered breathing, each tested with and without the device. The tongue device cut the number of louder snores (61–70 dB) from about 41 to 8 per hour of sleep and reduced micro-arousals, with trends toward fewer breathing events. The authors called for larger studies, and the device’s inventor, Dr. Robertson, was a co-author. (source)
• Deane et al., 2009 (Sleep). An independent randomized crossover trial in Sydney, Australia, comparing the AVEOtsd with a custom-made jaw splint in people with diagnosed obstructive sleep apnea. 27 patients were recruited and 22 finished. Both devices cut the apnea-hypopnea index by a similar amount (from about 27 to 13 events per hour with the tongue device, and to about 12 with the splint). But only 27% used the tongue device every night for at least six hours, compared with 82% for the splint; 86% reported the tongue device came off involuntarily during the night; and 91% of patients preferred the splint. (source)

The honest takeaway: the AVEOtsd can reduce snoring and keep the airway more open when it stays in, but comfort and retention decide whether it works for you night after night. It is cleared in the US only as an aid to reduce snoring, and the trials above were small and short. If you see the device marketed as a sleep apnea treatment, remember that is not what the FDA clearance covers.

Common Complaints and Fixes

“It falls off during the night”

This is the biggest issue in the research, and buyers commonly report it too. Fixes: push your tongue a little further into the bulb before releasing, squeeze the bulb a little harder, and avoid pressing your face into the pillow (stomach sleeping tends to break the seal). If it still won’t stay in after a couple of weeks, a different size or a different type of device is the next step.

Sore tongue tip

The suction pulls on a sensitive spot for hours. Use lighter suction and build up wear time gradually. Stop and see a doctor or dentist if the tongue becomes cut, ulcerated or numb.

Drooling or dry mouth

Excess saliva was the most common side effect with the tongue device in the Deane trial, and dry mouth was also frequent. Extra saliva usually settles as you adapt. A towel on the pillow helps in the meantime.

“I can’t breathe with it in”

Almost always a nose problem. If your nose is blocked most nights, a tongue device is the wrong choice. Our guide to the best mouthpiece for mouth breathers covers devices that leave a breathing gap.

Who the AVEOtsd Suits, and Who Should Skip It

A good fit

• Denture wearers and people with missing teeth. See our picks for denture wearers.
• People with crowns, bridges or implants who don’t want a tray pulling on dental work.
• Anyone whose jaw got sore from a jaw-advancing mouthpiece, or who has TMJ problems.
• Back sleepers who snore with their mouth closed and breathe easily through the nose.

Skip it, or talk to a doctor or dentist first, if you

• Have a blocked nose most nights, a deviated septum, nasal polyps or bad allergies.
• Are under 18 (the FDA clearance covers adults only).
• Have, or might have, sleep apnea. Loud snoring with pauses in breathing, gasping, choking or heavy daytime sleepiness should be checked with a sleep test before you treat the snoring yourself.
• Have central sleep apnea, a breathing disorder, or sores or injuries on your tongue.
• Have a strong gag reflex or tend to sleep face-down.

AVEOtsd vs CPAP

These are not substitutes. CPAP is a prescribed sleep apnea treatment that blows air through a mask to hold the airway open. The AVEOtsd is cleared in the US only to help reduce snoring. If you have been diagnosed with obstructive sleep apnea, don’t swap your CPAP for an over-the-counter device. Talk to your sleep doctor, who may be able to offer a prescribed oral appliance if CPAP doesn’t work for you. See sleep apnea mouthpiece vs CPAP and can snoring mouthpieces treat sleep apnea?

Price, Returns and Where to Buy

The official North American store lists the Medium at $99, Small and Large at $119, and a Medium twin pack at $159, with free standard shipping. That makes it more expensive than the Good Morning Snore Solution ($79.94) and about the same price as a premium adjustable jaw device.

Read the return terms before you order. The refund policy gives you 60 days: a single device can be returned if it hasn’t worked for your snoring, but you have to email the company first, try their advice, get a return authorization and post the device back to Dunedin, New Zealand at your own cost. With a twin pack, only one opened device is refundable. Defects are covered for 24 months. The product page also says opened, used devices aren’t refundable if you simply change your mind, so ask the company to confirm before relying on the guarantee.

Is AVEOtsd on Amazon?

When we checked, we couldn’t confirm an AVEOtsd listing sold by the manufacturer on Amazon. The maker states that devices bought from its own site are genuine, warns that cheaper products advertised elsewhere are not genuine AVEOtsds, and has posted a warning about counterfeit tongue devices. If you buy from a marketplace, check who the seller is, and expect the maker’s guarantee not to apply. Outside North America, the maker says the device is sold in most New Zealand pharmacies. Our guide on where to buy an anti-snoring mouthpiece has more general advice.

Cleaning and Care

Rinse the device after each use and brush it gently. Use a mild cleaner made for mouthguards or dentures rather than alcohol mouthwash, bleach or very hot water, unless the leaflet in the box says otherwise. Let it air-dry and store it in its case. Replace it if the bulb no longer holds suction or the silicone tears. See how to clean a snoring mouthpiece.

Alternatives to the AVEOtsd

• Good Morning Snore Solution: the other main suction tongue device. It is cheaper, comes in Regular and Small, and has a 30-day money-back guarantee. It is our top-rated tongue device. Compare them in AVEOtsd vs Good Morning Snore Solution.
• SnoreRx: a lower-cost adjustable jaw device for people with healthy natural teeth. See SnoreRx vs AVEOtsd.
• SnoreRx Plus: the hinged, take-apart version of SnoreRx, at almost the same price as an AVEOtsd. See SnoreRx Plus vs AVEOtsd.

Bottom Line

The AVEOtsd is a genuine, well-researched tongue-stabilizing device and a reasonable choice if dentures, dental work or jaw pain rule out a jaw-advancing mouthpiece and you breathe well through your nose. The research is also clear about its weak spot: many people struggle to keep it in all night. At $99 with returns shipped to New Zealand, it costs more and is riskier to try than the Good Morning Snore Solution. If you have healthy teeth and no jaw problems, an adjustable jaw device is usually easier to live with.

Frequently Asked Questions

Does the AVEOtsd anti-snoring device really work?

It can. In a randomized trial, the AVEOtsd reduced breathing events about as much as a custom jaw splint, and a small pilot study found fewer loud snores. But in that same trial most people found it hard to keep in, and 91% preferred the jaw splint. It works best for people whose snoring comes from the tongue and who breathe easily through the nose.

Is AVEOtsd FDA approved?

It is FDA-cleared, not approved: the FDA cleared it through the 510(k) process in September 2023 (K231663) for over-the-counter use as an aid to reduce snoring in adults 18 and older. “Cleared” is the normal route for snoring devices. The clearance does not cover sleep apnea.

Do you need a prescription for AVEOtsd in the US?

Not anymore. Older articles say a prescription was needed, which was true when the device was sold through US dental channels. The 2023 FDA clearance is for over-the-counter use, and the official North American store sells it directly.

How much does AVEOtsd cost?

On the official North American store, $99 for a Medium, $119 for a Small or Large, and $159 for a Medium twin pack, with free standard shipping (checked October 2026).

Can I buy AVEOtsd on Amazon?

We couldn’t confirm a manufacturer-run Amazon listing. The maker warns about counterfeit tongue devices and says only devices from its own site are guaranteed genuine, so the official store is the safest place to buy.

Is AVEOtsd better than CPAP?

No. They do different jobs. CPAP is a prescribed treatment for sleep apnea; the AVEOtsd is cleared only to help reduce snoring. Don’t stop CPAP without talking to your doctor.

Which AVEOtsd size should I buy?

Medium, unless you know your tongue is unusually large or small. The maker says over 90% of people fit the Medium.
