Neslemy, Travalisse & Averia Anti-Snoring Mouthpieces Compared: What to Know Before You Buy
How Neslemy, Travalisse and Averia Really Compare Before You Spend Your Money
Snoring is one of the most common sleep complaints there is. It strains relationships. It costs you rest. And when you are tired enough, you will try almost anything to quiet it down.
Enter the new generation of anti-snoring mouthpieces the internet has to offer.
Three brand names that are popping up these days are Neslemy, Travalisse, and Averia. They look the same at first glance. Their websites look similar. Their claims sound familiar.
So what are they? How do they compare?
Let’s take a look.

Neslemy, Travalisse and Averia are trademarks of their respective owners. We are not affiliated with, endorsed by, or sponsored by any of them. Statements about those products reflect information publicly available as of July 28, 2026 and are our opinion based on that information.

What They Each Say They Provide
All three brands claim to offer what’s commonly referred to as a mandibular advancement device (MAD). It moves your bottom jaw forward slightly to help hold your airway open while you’re sleeping.
That’s a valid premise, and it’s what the majority of anti-snoring mouthguards are designed to do. If you want the background on why airway narrowing causes the noise in the first place, start with why people snore.
But here’s the catch: transparency.
Comparative Design: Why They May Look Familiar
If you browse product pictures on the Neslemy, Travalisse, and Averia sites, you’ll notice something interesting:
- Similar boil-and-bite design
- Similar double-tray design
- Similar hinge positioning
- Similar adjustment method
They look similar to many other anti-snoring mouthpieces being offered for sale across major ecommerce platforms.
In our opinion, when different companies sell mouthpieces that look this alike with only slight marketing variations, two things may be happening:
- They’re a private-label generic product
- They were made by the same contract manufacturer
Neither scenario is automatically “bad,” and we are not suggesting anything improper. But both raise fair questions about quality control, clinical support, regulatory status, and whether warranties will be honored long-term.
FDA Clearance: What We Found
Devices intended to help reduce snoring by repositioning your jaw are typically regulated as medical devices. When considering the purchase of a snoring mouthpiece, it’s smart to look for information about whether it’s FDA cleared.
On July 28, 2026, we searched the FDA’s public 510(k) Premarket Notification database for the brand names Neslemy, Travalisse, and Averia and did not find a matching listing under any of those names. Clearances are sometimes held under a manufacturer’s name rather than a brand name, so a brand-name search is not the last word. You can run the same search yourself using the link above.
What that means (in plain English):
It does not automatically mean a device is unsafe or cannot be sold. It does mean the paperwork is not sitting where a buyer can easily find it, so it is worth asking the seller directly.
Before you buy, ask:
- Is there an identifiable FDA clearance number?
- Will the vendor provide it upon request?
- Who manufactures the device, and where?
If a brand can’t answer those three questions clearly, that’s something to think about.
Similarity in Marketing Claims and Site Design
Here’s another pattern that shows up across these brands:
- Similar product descriptions
- Similar “before and after” presentation styles
- Similar feature lists
- Aggressive discounting
Similar marketing does not prove wrongdoing. But when the names change and the product appears nearly identical, it can mean you’re buying a re-branded product rather than something with clear differentiation and verifiable standards.
Manufacturer Disclosure
Any medical device should clearly tell you:
- Where it was made
- What materials were used
- Whether it’s BPA-free
- Whether it was made in a certified or regulated facility
If a brand doesn’t disclose where its device was made and how it aligns with manufacturing and quality protocols, buyers should notice.
Many generic boil-and-bite mouthpieces are manufactured and mass marketed across ecommerce platforms with minimal transparency. That creates questions around material variability, adjustment quality, durability, and whether warranties are meaningful.
Transparency builds trust. Silence does not.
Side Effects: What to Be Aware Of
This part is not brand-specific. Mandibular advancement devices as a category, including ours, can cause:
- Jaw pain
- Tooth pain
- Changes in bite
- Excessive salivation
- Fitting issues
Most of these are mild and ease as you adjust to wearing a device, but they are worth knowing about before you buy anything in this category. Talk to your dentist if symptoms persist.
With adjustable devices, precision matters. There can be a wide range in how finely a mouthpiece advances your jaw. Small, controlled increments are easier to live with than a device that jumps in coarse steps.
Buying Protection Suggestions
Before purchasing any Neslemy, Travalisse, Averia, or similar MAD device, consider:
- Search the official FDA 510(k) database yourself
- Look for clear customer service contact information
- Find out where it was made and whether the facility was regulated
- Look for reviews on platforms other than the vendor’s own site
- Read the return policy before you buy
Snoring appliances are serious business. When you’re sleep deprived, urgency overrides caution.
Pump the brakes. Do your due diligence first.
If you want a benchmark for what full disclosure looks like, VitalSleep is FDA cleared, made in the USA, and publishes its return policy, warranty, and support contacts openly.
Final Thoughts
Neslemy, Travalisse, and Averia appear to sell closely similar anti-snoring appliances online. The rationale behind MAD mouthpieces is sound. The public information behind these brands is thin.
That doesn’t mean they shouldn’t be tried. But it should prompt a second look from anyone considering spending money on a device that can affect jaw positioning and airflow.
When it comes to sleep and your airway, missing information is worth noticing. If a company won’t clearly tell you what the product is, where it’s made, and how it’s classified, that’s something you should know about. Comparing devices side by side is a fast way to spot the difference in guarantees and transparency.

FAQ
Are Neslemy, Travalisse, and Averia the same mouthpiece?
We don’t know, and none of them says publicly. They appear closely similar in design and marketing. When multiple brands sell mouthpieces that look this alike, it can indicate private-label versions of a generic product or manufacturing by the same supplier.
Are these anti-snoring mouthpieces FDA cleared?
When we searched the FDA 510(k) database on July 28, 2026, we did not find a listing under the Neslemy, Travalisse, or Averia brand names. Clearances can be held under a manufacturer’s name instead, so ask the seller for a clearance number and verify it directly through the FDA’s official database.
What should I check before buying an anti-snoring mouthpiece online?
Confirm FDA status, manufacturing transparency, materials used, return policy terms, customer service accessibility, and reviews outside the seller’s own website.
