Mandibular Adjustment Devices, or MADs, work to reduce snoring and sleep apnea, which has been known to cause a myriad of health issues. One such device, the ZQuiet, promises to be the best and most comfortable mouthpiece on the market today.

The mouthpiece is designed in two sizes that will help lift the throat and jaw, as well as prevent the blockage of air passages. We’ve taken a look at various reviews, breakdowns, and other MADs to answer the question: Does the ZQuiet anti-snoring mouthpiece really stop snoring?

In this review, we will give you a quick reference to some of our favorite – and most frustrating – things about the mouthpiece.

General Information

ZQuiet is a nighttime sleep aid company that produces a single product – the ZQuiet mouthpiece.

The device, as we’ve mentioned before, is a mandibular adjustment device that is designed to help you sleep better at night.

The mouthpieces are designed to be purchased either directly from the company or licensed retailers. This means you won’t need a doctor’s note to pick up this product. If you feel as if your snoring habit has gone on long enough, you can order a mouthpiece like this today.

ZQuiet is also a fully-licensed retailer in the mouthpiece market, is FDA-approved, and is highly recommended by several oral professionals.

How Does ZQuiet Work?

Snoring occurs primarily when air passages are obstructed. While common causes of air passage obstruction include colds or allergies, much of the time, the airways are obstructed by the natural weight of the body.

Muscle, tissue, and excess fat on the neck and under the head weigh down the esophagus and other air passages. When these airways become constricted, the passages open and close rapidly, creating that infamous snoring sound along the way.

To avoid this, the ZQuiet mouthpiece lifts this tissue from the airways by protruding the lower jaw. Moving the lower jaw forward creates negative space in the back of the throat and lifts away the problematic tissue, allowing the airway to breathe.

This device comes in two sizes to help you find the best protrusion and most comfortable fit, while still preventing snoring and sleep apnea.

Living Hinge Technology

ZQuiet’s primary selling point seems to be their focus on a special hinge at the back of the device. This hinge allows the lower jaw to remain protruded while the user talks, yawns, or even drinks water.

This hinge greatly reduces the user’s discomfort with using a MAD, which can, in turn, promote consistent use of the product.

Enhanced Flexibility

Another feature of the ZQuiet mouthpiece includes the use of highly flexible plastics. These plastics are said to mold to the teeth to ensure comfort, as well as allow the mouth to move more freely in the night.

Multiple Sizes

ZQuiet Mouthpiece Review 2020 3

The mouthpiece ships in two sizes that must be purchased together. In essence, these two devices both make up the full ZQuiet MAD. Here’s how it works:

The first few nights, users are to wear the “Size 1” mouthpiece, which is smaller and more comfortable for those with smaller mouths. However, if snoring persists or this size is too small, users can move to the “Size 2” mouthpiece to better combat snoring.

Very few MADs are able to offer two mouthpieces with their products, but ZQuiet manages to do so—and at a price that’s lower than most of the competition.

How is ZQuiet Different From Other Anti-snoring Mouthpieces?

When I worked with our team of professionals to develop ZQuiet, my primary objectives were Comfort, Ease of Use, and Effectiveness. The resulting design contains unique features that inherently set it apart from other mouthpieces.

The biggest differentiator is the patented living hinge. This hinged design allows freedom of jaw movement, including side-to-side and the ability to open and close. Many other devices force the jaw into a clenched bite without any ability to open the mouth or move the jaw naturally, something I find to be uncomfortable and disturbing to my sleep. Another benefit to this design is that you can talk without removing the device and even drink water or take pills, something many people do just before sleeping.

The other big differentiator is the fact that our mouthpiece is ready to use right out of the package without any complex molding, boiling, or impressions. In fact, it’s the easiest mouthpiece to use for that very reason.

One thing that most people don’t realize is that all moldable devices require a hard plastic outer shell to maintain the shape and to provide the advancement. This creates excess bulk that some people, especially with smaller mouths, find difficult to tolerate. The device’s slim and low-profile design won’t make you feel like you just overstuffed your mouth.

As someone that has tried many different mouthpieces, I understand that fit and comfort varies from one person to another. We don’t claim to be the best mouthpiece for everyone, but many people prefer the simplicity, comfort and unique design of ZQuiet, and we hope that you will be one of them.

How Effectively Does ZQuiet Stop Snoring?

SnoreLab[1], the leading analysis app for iPhone and Android, examined data from a group of ZQuiet users and their findings are quite promising:

  • 70% of people trying the mouthpiece had their snoring significantly reduced.
  • Snoring was effectively eliminated for more than half of those people.
  • The average reduction in SnoreLab’s Snore Score was 70%.

The evidence behind ZQuiet’s effectiveness makes it one of the best anti-snoring devices available in the market.

Considerations before buying one

Despite of the great evidence behind the device, there are some cases where it may not be the best anti-snoring solution for you:

  • If your mouth is smaller than average, you may run into some trouble getting it to fit, but it can be cut down to size.
  • Avoid if you have dentures, loose teeth, and other dental appliances.

ZQuiet FAQ’s

How Do You Fit the ZQuiet?

The ZQuiet is worn in the mouth. Right out of the box, there is no adjustment needed. Simply open the packaging, locate the “Size 1” mouthpiece, and place in the mouth. Just be sure to place the top and bottom pieces correctly. The manufacturer recommends that you wear their mouthpieces for about 20 to 30 minutes during the daytime to help your mouth get adjusted to the new normal. MADs like the ZQuiet mouthpiece can cause discomfort and some drooling in the first few days. This is considered to be the “break-in” period when it comes to mouthpieces and is entirely normal. After a few days have passed, you should be able to easily sleep with the mouthpiece on.

Where Do I Buy ZQuiet?

Like other MADs, ZQuiet cannot be purchased through major online retailers like Amazon. In fact, their website is one of the few places where the product can be purchased. However, some drug stores nationwide have begun to stock this product. While we cannot direct you to a product locator, you may want to consider calling your local pharmacy to see if the device is in stock.

How Do I Clean the ZQuiet Mouthpiece?

There are two primary ways you can clean your device. The first is to sanitize the product using materials around the house. To do so, place the mouthpiece in boiling water and wait for a minute or two. Be sure not to leave the mouthpiece in there too long, as the product may begin to warp. Then, wait until warm and clean off any gunk or debris. Your mouthpiece should be sanitary and ready to go. If you’re struggling to get to debris lodged in tight spaces, you may also want to use a toothbrush to make sure all debris is removed. The most recommended way to clean the ZQuiet is with their proprietary cleaning solution. This can be purchased as an add-on at checkout when buying your device directly from the manufacturer.

How Much Does ZQuiet Really Cost?

The cost of the ZQuiet tends to fluctuate, but it can be purchased for around $70 before taxes as of today. This makes this mouthpiece one of the most affordable mouthpieces on the market. If you’re hesitant about purchasing one, why not try it first? ZQuiet offers a 30-day trial period that allows customers to use the product without paying full price. However, it should be noted that the trial will cost you $10, even if you return the mouthpiece.

How Long Will Does the ZQuiet Mouthpiece Last?

According to the official website, you can use the product for about six months before needing to replace it. However, most reviews report that the product will last up to 1 year or more. Generally speaking, you can use the ZQuiet mouthpiece until the materials decay or snoring returns.

Can I Use The ZQuiet Mouthpiece With Dentures?

Unfortunately, no. The ZQuiet mouthpiece needs to make contact with mostly true teeth to function. While one or two false teeth is acceptable, those with dentures, or braces for that matter, should not use the mouthpiece. If you wear dentures or have braces and want to combat your snoring habit, be sure to speak to your physician or orthodontist to find the best device for you.

What Size Should I Order?

The ZQuiet mouthpiece only comes in two sizes, which cannot be purchased separately. When you order a mouthpiece, both sizes are shipped directly to you.

Is ZQuiet Right For Me?

Most people struggle to decide between the ZQuiet and other MADs, like the Zyppah or SnoreRx mouthpieces. When it comes to customer reviews, most ZQuiet reviews are mixed to positive.

Many people enjoy the affordability of the product when compared to what you get right out of the box. The smaller size is also preferable for many since a number of MADs do not allow you to close your mouth.

Generally speaking, the mouthpiece is also more affordable and easier to use than other MADs. With a patented hinge design, this product is also one you can use if you wish to talk while using the product. Most other MADs will lock your jaw.

However, this mouthpiece cannot be custom molded, which is a serious problem for many. Likewise, while it lasts for a long time, the durability of the product is questionable when you compare it to premium MADs.

If you have never purchased a MAD before and want to try one out, we think the ZQuiet is the perfect starter mouthpiece. However, if you’re hoping for adjustability and custom molding, the SnoreRx may be more up your alley.

Final Thoughts

ZQuiet Mouthpiece Review 2020 4

Regardless of whether you choose to go with this mouthpiece or another, we hope you consider purchasing a mandibular adjustment device to make sure you keep your snoring to a minimum.

We think the ZQuiet isn’t for everyone, but if you’re looking for a simple device to stop your snoring, it might get the job done. Utilizing the 30-day trial, you can find out for yourself whether or not this device is right for you without much cost to you.

We think that risk is well worth the reward.
