ZQuiet Mouthpiece Review

Snoring affects not only the snorer but also the person lying next to them. If you’re very loud, you might wake the kids down the hall or the neighbors. Anti-snoring mouthpieces are often a quick, relatively inexpensive fix.

Silencing a snore may be easily done with the help of an anti-snoring mouthpiece. This review looks at ZQuiet, an affordable over-the-counter option for better sleep. Use this guide to find out the product specifics, how it helps, how much it costs, customer reviews, and our rating of ZQuiet.

What is ZQuiet and How Does it Work?

For chronic snorers (and their suffering sleep partners), there are two main types of anti-snoring mouthpieces to achieve a quieter night’s rest.

  • A Mandibular Advancement Device (MAD) eases snoring by pushing your jaw forward to keep the tongue from falling back and blocking the airway.
  • A Tongue Retaining Device (TRD) restrains the tongue so that it won’t fall into the airway and obstruct breathing which is a leading cause of snoring.

ZQuiet’s anti-snoring mouthpiece is a Mandibular Advancement Device (MAD) designed to help with tongue obstruction. Advancement refers to “pushing forward” which is what the mouthpiece does to your lower jaw.

The tongue is a long muscle that attaches at the back of your mouth and throat. A “tongue base snorer” is someone that’s noisy while sleeping because the base of their tongue drops back to block the airway. When the MAD pushes your jaw forward, it prevents the base from blocking your breathing.

How ZQuiet differs from other anti-snoring mouthpieces

Of the various MADs on the market designed to help stop snoring, ZQuiet differs in a couple of ways. First, it doesn’t mold to your bite. It’s simply a soft plastic mouthpiece that goes over your teeth, much like a tooth whitening tray might except there’s a second tray and they are hinged together.

Second, ZQuiet sends you two mouthpieces, distinctive in design. The two advance your jaw at different increments, so you get a different effect with each. They recommend you start with the one that pushes your jaw forward slightly less than the other.

A big differentiator is what the company calls its “living hinge.” Once in your mouth, the MAD allows you to open and shut your mouth with ease and keep “living” your life. You can talk, drink water, and breathe easy while wearing the mouthpiece.

Critical Data on Mandibular Advancement Devices

Mandibular Advancement Device (MAD)
Function: MADs work by shifting the lower jaw (the mandible) to keep your tongue from shifting and blocking the airway
Sizing: Over-the-counter MADs are self-fitted via “boil and bite” and prescription MADs are made by dentists and custom-molded
Adjustment: MADs may feature an option to adjust subtly how far it pushes the jaw forward
Material: MADs are usually plastic or silicone resin
Breathing Function: It varies by design, but MADs help wearers breathe more freely through their mouth and often have breathing holes or spaces built-in
Side Effects: Initial jaw pain that may dissipate, excessive drooling (may lessen with use), dry mouth, tooth pain, further loosening of already-loose teeth, changes in your bite
Bruxism aid?: Some MADs may improve night-time teeth-grinding
Denture-friendly?: MADs shouldn’t be worn with dentures, but you may be able to order custom dentures that work like a MAD
Expected Lifespan: 12-24 months is typical depending on quality of materials, but some might last as little as six months
Average Cost: OTC MADs run $50-150 and $500-1,000 for a custom MAD from a dental lab


Product Specifics

Let’s look at ZQuiet construction, how it works, and whether this is a good solution for your snoring problem. ZQuiet’s two mouthpiece solution means you have two options to choose from, but they are almost identical aside from how far forward they move the jaw.


The ZQuiet is a Mandibular Advancement Device (MAD) designed to relieve snoring by shifting your tongue position.


The ZQuiet is a medical-grade thermoplastic polymer (strong, flexible plastic) that is latex-free and BPA-free.

Sizes available:

There are two mouthpieces in the kit, both the same size. The difference is how much they move the jaw. It can be trimmed to fit smaller mouths. If your mouth is large, you might not find a good fit with ZQuiet.


The ZQuiet doesn’t mold to your mouth. It’s ready-to-use out of the box. The only customization is the two options and how they differ in shifting your jaw forward.

Ability to re-adjust:

You can’t readjust beyond the baseline construction, but you can trim and file the edges of the mouthpiece for greater comfort which may be necessary if you have a smaller mouth.


As with most MADs, ZQuiet is highly effective and works well for about 90% of users.

Side effects:

The mouthpiece may increase salivation because it props your mouth open. Alternately, you might experience dry mouth because of increased airflow on your tongue. The more aggressive of the two mouthpieces can cause some jaw soreness.

Ease of breathing:

It’s very easy to breathe while wearing ZQuiet because it doesn’t pull your mouth closed. Your jaws are wide open, so there’s lots of airflow.

Ease of cleaning:

Clean with warm water, dish soap, and a toothbrush. Do not use toothpaste to clean the ZQuiet – the manufacturer cautions that it could disintegrate the surface and cause discoloration.

Denture friendly:

The ZQuiet should not be worn with dentures. It will press on them and cause discomfort and can damage them.

Bruxism concerns:

Teeth grinders should find some relief from ZQuiet’s soft molded plastic that keeps your upper and lower jaws from interacting while you sleep. Grinding may reduce its lifespan.


There is no warranty, but a 30-day trial for which you’ll pay less than $10 to test-drive the dual mouthpiece anti-snoring solution in your home.


This MAD is comfortable soft plastic but may not be as durable as some other anti-snoring mouthpieces. You should get at least 12 months of usage out of ZQuiet, and perhaps longer.


The ZQuiet mouthpiece costs $9.95 (+$8.97 shipping and processing fee) to try it and then you’re charged $79.95 if you keep the mouthpieces past the 30-day trial. It’s not a 100% refund since they will keep the trial fee.

Fitting the ZQuiet Mouthpiece

There is no boil-and-bite fitting for ZQuiet. It markets itself as being ready to use out of the box. However, there are some modifications you can make to get it to fit better in your mouth. There are two mouthpieces in the kit, each that pushes the jaw forward differently.

You’ll see right away that on one, the bottom part sticks further forward. The company recommends you start with the device that protrudes less. However, if either comes up too far on your gums and rubs the inside of your mouth, you can trim it.

The company’s official FAQs recommend that if you need a better fit to use small scissors to trim the soft plastic and then buff out the rough edges using an emery board or nail file. Aside from this, there is no other physical fitting or adjustment to make.

One recommendation they offer is to soften it by running it under warm/hot tap water before wearing. However, you should never put this mouthpiece in extremely hot water. The ZQuiet mouthpiece is a thermoplastic polymer that will melt if you overheat it!

What Do Customers Think of ZQuiet?

In addition to the over-the-counter ZQuiet, there are three pro-level versions of the product with advanced tech features. We examined customer reviews for the baseline ZQuiet anti-snoring mouthpiece.

Most customers report successful outcomes in their reviews, some discomfort as they adjust to the mouthpiece, but a better night’s sleep. The “living hinge” aspect differentiates ZQuiet but some users report it contributes to it falling out during the night.

Even consumers that found the mouthpiece didn’t work for them were impressed with the personal touch of customer service and noted the company founder often interacts with buyers to learn more about why the mouthpiece didn’t work for them.

ZQuiet has an A+ rating with the Better Business Bureau. The chief issues are mishandled returns, but the company took great care to address the issues and refund money, according to BBB records. They have no open complaints.

Common feedback from customer reviews include:

  • Users find ZQuiet works really well for them or not at all
  • Adjustment period with jaw soreness and salivation
  • Might not stay snug in your mouth while sleeping

Is ZQuiet the Best Option for You?

There is no solution to snoring that works for everyone. It depends on the underlying cause of your snoring, size and sensitivity of your mouth, and other factors. Overall, MADs enjoy a high rate of success in snoring cessation and many buyers really like ZQuiet.

ZQuiet might work well for you if:

  • Experience anxiety with other MADs because your jaws feel trapped
  • Want a mouthpiece that’s less constricting, lets you talk, and use your mouth

ZQuiet is not recommended for:

  • People with very small or very large mouths since there’s no fit or adjustment feature
  • Those with dentures, loose teeth, and other dental appliances

Common complaints:

There are a few common complaints reported by some buyers. These issues may include:

  • Mild jaw soreness but less frequent with the moderate of the two devices
  • Some dry mouth or drooling because your mouth stays open while sleeping
  • Might not work for some people since it’s not fitted to your bite
  • May fall out of your mouth while sleeping since it’s not a tight fit
  • Some report issues with being charged after returning mouthpiece
