Quick answer: SnoreRx Plus ($99.99) and AVEOtsd ($99) cost almost exactly the same, so price won’t decide this one. Your mouth will. If you have healthy natural teeth, SnoreRx Plus is the better choice for most people: it adjusts in 1 mm steps, it stays on your teeth, and its hinge fixes the “locked shut” feeling that drives many people away from jaw devices. AVEOtsd is the pick if you wear dentures or can’t have your jaw held forward, as long as you breathe easily through your nose.
SnoreRx Plus is a hinged, adjustable mandibular advancement device (MAD) that moves your lower jaw forward. AVEOtsd is a silicone tongue-stabilizing device (TSD) that holds your tongue forward with suction. Both aim to stop the base of the tongue from narrowing your airway; they get there by very different routes.
How we tested: We bought and tested SnoreRx Plus ourselves (see our hands-on notes and video review below). We haven’t tested AVEOtsd; its details come from the maker’s specs, its FDA records and published research.

Quick Verdict
- Choose SnoreRx Plus if you have healthy natural teeth, no TMJ disorder, and either breathe through your mouth at times or tried a rigid mouthpiece and hated not being able to open your mouth.
- Choose AVEOtsd if you wear dentures, have few teeth or extensive dental work, or a jaw device has already caused jaw pain, and your nose is clear at night.
- See a doctor first if your snoring comes with pauses in breathing, gasping or daytime sleepiness. Neither device is a sleep apnea treatment.
- Our hands-on test: SnoreRx Plus cut our tester’s snoring by more than 70% at its default setting. We haven’t tested AVEOtsd.

The Hinge: Why It Matters in This Comparison
People usually start looking at tongue devices for one of two reasons: they can’t wear a jaw device (dentures, dental work, jaw pain), or they tried a rigid jaw device and couldn’t sleep with their mouth clamped shut. SnoreRx Plus is aimed squarely at the second group.
The original SnoreRx locks two trays together, so your mouth stays in one position all night. SnoreRx Plus splits the device into three trays. The upper tray hooks onto the back of the middle tray, and that connection works as a hinge: you can open your mouth slightly, swallow and yawn with it in. The lower tray still slides forward in numbered 1 mm steps to set how far your jaw is held forward.
So if your reason for considering AVEOtsd is “jaw devices feel claustrophobic,” try the hinged design first. If your reason is “I don’t have the teeth for it” or “my jaw joint can’t take it,” the hinge doesn’t help, and AVEOtsd is the right direction. For the full breakdown of what the Plus adds over the original, see SnoreRx vs SnoreRx Plus.
Staying In All Night
A device only helps while it is in your mouth. This is where the two differ most in practice.
- SnoreRx Plus is molded to your teeth and snaps on. When it falls out, it is usually because the impression was too shallow, which a second fitting can fix. The other thing to check is that the upper tray is hooked fully onto the middle tray after you adjust it.
- AVEOtsd is held only by suction on your tongue. In a randomized trial of AVEOtsd against a jaw splint, 86% of participants said the tongue device came out involuntarily during the night, against 9% for the splint (Deane et al., 2009). More suction, pushing the tongue further in, and not sleeping face-down all help.
That trial is covered in more detail, including the snoring results, in our SnoreRx vs AVEOtsd comparison.
Comfort: What Each Device Asks of You
SnoreRx Plus
The common early complaints are jaw, tooth or gum soreness, extra saliva or dry mouth, and a bite that feels different for a while in the morning. The maker suggests wearing it for 1–3 hours while awake for the first 2–3 days, starting at the 1 mm setting, and spending at least three to five nights on each setting before moving forward. If a setting makes your jaw ache, go back one step. Persistent pain or a bite that doesn’t return to normal means stop and see a dentist (jaw pain from a snoring mouthpiece).
AVEOtsd
Nothing presses on your teeth or jaw, so there’s no jaw ache or bite change. Instead, expect a tender tongue tip, extra saliva or dry mouth, and some irritation where the flanges rest against your lips. Use the least suction that keeps it in, and practice wearing it while awake for a few evenings. A blocked nose makes it unusable, so deal with congestion first.
Cleaning and Upkeep
SnoreRx Plus comes apart: unhook the upper tray and you can brush each piece, including the hinge area where buildup tends to collect. AVEOtsd is one piece of soft silicone with no joints, so it’s quick to rinse and brush. Neither maker publishes a lifespan. Boil-and-bite devices like SnoreRx Plus typically last about a year with nightly use, less for heavy teeth grinders; replace AVEOtsd if the bulb stops holding suction or the silicone tears. See how to clean a snoring mouthpiece.
Price and Guarantee: Nearly Equal Cost, Different Risk
At $99.99 vs $99, and $154.98 vs $159 for two, the cost is a wash. The difference is how easy it is to get your money back if the device doesn’t suit you:
- SnoreRx Plus: a 30-night money-back guarantee for new customers who buy directly from snorerx.com (product price only).
- AVEOtsd: the refund policy allows 60 days for a single used device that didn’t help, but you email the company first, follow their advice, get an authorization and ship it to New Zealand at your own cost. Only one opened device from a twin pack is refundable.
Whichever you choose, start using it as soon as it arrives so you are past the break-in period before the return window closes.
AVEOtsd: When It’s the Right Call
SnoreRx Plus’s instruction booklet rules it out for people who wear dentures, braces or other dental appliances; have loose teeth, abscesses or advanced gum disease; have a history of TMJ disorder; have central sleep apnea or a respiratory disorder; or are under 18. It also says to check with your dentist first if you have implants, crowns or caps. If any of the first group applies to you, a tongue device is the realistic over-the-counter option, and AVEOtsd is a well-established one (see best mouthpieces for denture wearers).
If you go the tongue-device route, compare AVEOtsd with the cheaper Good Morning Snore Solution in AVEOtsd vs GMSS before you buy.
Our Hands-On Test: SnoreRx Plus
We bought SnoreRx Plus and tested it ourselves. It arrived with the fitting handle already in place, plus a case and instructions. We fitted it with a cup of water boiled in the microwave: 60 seconds in the water, a firm 30-second bite and 5 minutes in cool water, which left a clear impression of the teeth. Tested at the factory default setting, with no extra advancement, our recordings consistently showed snoring reduced by more than 70%. If you do advance it, the instructions say to go 1 mm at a time, every few nights.
Full details, photos and screenshots are in our SnoreRx Plus review.
What our testing adds to this comparison: SnoreRx Plus worked well for us at its starting setting, before any extra advancement. AVEOtsd is the choice if you can’t wear a jaw device, but our notes on it come from the maker, the FDA and published research.
One tester’s nights are a real-world example, not a clinical trial. Snoring varies from person to person and night to night, and a snoring app or fingertip oxygen recording is not a sleep test.
Who Should Talk to a Doctor First
Snoring can be a sign of obstructive sleep apnea. If you have loud snoring with pauses in breathing, gasping or choking, morning headaches or heavy daytime sleepiness, get a sleep test before trying either device. Both are sold to reduce snoring, not to treat sleep apnea. Our article on whether snoring mouthpieces can treat sleep apnea explains the options a doctor or dentist can prescribe.
The Bottom Line
For the same money, SnoreRx Plus gives most people with healthy teeth a more reliable result: a fit that stays put, precise adjustment, a hinge that lets your mouth move, and room to breathe through your mouth. AVEOtsd is the better tool when your teeth or jaw rule out a jaw device, and your nose is clear enough to rely on all night.

Frequently Asked Questions
Is SnoreRx Plus better than AVEOtsd?
For people with healthy natural teeth and no jaw joint problems, usually yes: it is adjustable, stays on the teeth and lets you open your mouth slightly. AVEOtsd is better when dentures, dental work or jaw pain rule out a jaw device.
Can I use SnoreRx Plus with dentures?
No. The instruction booklet lists dentures as a reason not to use it. AVEOtsd doesn’t touch the teeth, so it can be used by denture wearers.
Which is better for mouth breathers?
SnoreRx Plus. Its open front allows some airflow through the mouth. AVEOtsd closes your lips around the bulb, so you must breathe through your nose. See the best mouthpiece for mouth breathers.
Do they cost the same?
Almost. SnoreRx Plus is $99.99 and the AVEOtsd Medium is $99 on the official stores (October 2026). Two-packs are $154.98 and $159.
Can I use either for sleep apnea?
No. Both are over-the-counter aids for snoring in adults. If you have or suspect sleep apnea, see a doctor; CPAP or a prescribed oral appliance may be appropriate.
