What is ZQuiet?

ZQuiet is an anti-snoring mouthpiece that was made to effectively treat snoring.

It's a single piece device that has a resilient hinge that moves your lower jaw forward to reduce the likelihood of snoring.

Review Contents

Ratings/ Pros And Cons


  • Does not require water, a heating source or any tools, making it easy to use on the spot

  • Orders include two devices instead of just one (each one advances the jaw a different amount for comfort and effectiveness)

  • ZQuiet offers a 60 Night Better Sleep Guarantee™. Enjoy it for a full 60 nights worry free.


  • ZQuiet is not custom fit to your teeth so it may be less comfortable or cause soreness

  • Not for people with full dentures (can be used by those with partial dentures)

  • May require dipping in hot water to feel comfortable wearing it at night

How It Works

The anti-snoring mouthpiece works by keeping your jaw in place to prevent it from falling back over your airway. This is what causes snoring in the throat of most people. They gives you two (2) different devices which work by advancing your jaw to different positions.

ZQuiet is an easy to fit anti snoring device mouthpiece. You simply put it in your mouth before you go to sleep with the "V" notch facing up.

It does not form a custom mold of your teeth, like most other other anti snoring products and mouthpieces on the market, so you do not need any special equipment, just open the package and begin using immediately.

Video Review

This is a video review of the ZQuiet mouthpiece for Snoring Mouthpiece Review that shows how it works, results of wearing it and how to clean it. The results in the video show that it can reduce snoring but may cause some discomfort during its initial use.

What's Included

What's included in the ZQuiet box?


  • Two (2) ZQuiet anti-snoring mouthpieces are included in your order

    • They are different sizes, you try the first ("Size A") to see if it fits and then the second if you need more jaw advancement

  • Travel case (fits both mouthpieces)

  • Booklet titled: "25 Ways to Enhance Intimacy In Your Relationship" (Update: this is now an e-booklet)

  • Booklet titled: "25 Tips for a Better Night's Sleep" (Update: this is now an e-booklet)

  • Booklet titled: "Instructions for Use and Care" (Update: this is now an e-booklet)

    • Shows how to wear and take care of the mouthpiece


  • The above, left, ZQuiet is the "Size A" version. It's the smaller (less forward) mouthpiece that comes in the box. This model may be more comfortable but it doesn't advance the lower jaw forward as much as the other model that is included in the box. It is recommended to start with the first model and then use the second one if snoring persists.

  • The above, right, is a picture of the 2nd ZQuiet which is included in the box. It has a much further forward lower jaw position. This advancement is more likely to open the airway and stop snoring when it is used.

Precautions/ Health Info

Is jaw soreness common with ZQuiet?

Each person will adjust to wearing the anti-snoring mouthpiece differently. Some people may not feel any soreness, while others make take weeks to adjust to it.

Soreness can occur because the back advancing the lower jaw is being moved forward, which reduces snoring. This process can involve some initial conditioning of your jaw muscles.

Is ZQuiet FDA Cleared?

Yes, the anti-snoring mouthpiece has been cleared by the FDA since 2009 as a class II intraoral device, designed for the treatment of snoring. (see official FDA document)

Does ZQuiet work for people with braces?

If you have braces, you should see a dentist before using it.

Who should try ZQuiet?

ZQuiet is designed for people 18 years of age and older who seek treatment for their snoring. If you snore and want a doctor-free, fast and inexpensive solution to stop snoring, you should consider trying ZQuiet.

Who should not use ZQuiet?

Don't use ZQuiet if:

  • You are under 18 years of age

  • Have full dentures

    • It is safe to use with partial dentures

  • Have central sleep apnea

  • Have TMJ problems

  • Those with caps, crowns or bridge work

Product Details

Does ZQuiet actually work?

Yes, it can reduce snoring when worn correctly all night. See more details on this page for actual patient results.

How much lower jaw advancement does ZQuiet offer?

The less forward, "Size A" offers approximately 3 mm of advancement while the more forward mouthpiece offers approximately 8 mm of advancement.

Is ZQuiet a boil and bite mouthpiece?

No, it does not require any boiling or molding. It can be used exactly as provided, immediately after you buy it.

In comparison, “boil and bite” devices may be more rigid, bulky and can make mouth breathing difficult because of a fixed size airway.

Unlike boil-and-bite mouthpieces, it doesn’t require any molding. The design fits the majority of mouths and it is ready to use right out the box. You do indeed just "pop it in" before going to sleep.


Diagram 1: The above is a picture from ZQuiet's booklet which shows the parts of ZQuiet, which side goes up and where the airflows.


Diagram 2: The above is a picture of how to place ZQuiet into your mouth to prevent snoring.

ZQuiet Effectiveness

  • According to data retrieved from SnoreLab (a snoring app), ZQuiet was responsible for reducing snoring for 70% of people who tried it.

  • For more than 50% of those people, snoring was effectively eliminated.

  • The average reduction in snoring intensity (as measured by the SnoreLab Snore Score) was 70%.

  • We reviewed ZQuiet independently and found that it reduced snoring (see below).

How quickly will I see results from ZQuiet?

You should expect to see results on the very first night you wear it.

How do I setup ZQuiet?

No setup is required for it, you can use it immediately after you receive it.

How big is the airway opening?


When closed, the ZQuiet anti-snoring mouthpiece has an airway opening of only 3 millimeters, this is a rather small opening compared to some other mouthpieces. It is not that important to compare it to other mouthpieces on the airway opening though because it is flexible and can be open widely.

The size of the airway opening is important in most mouthpieces because larger airway openings make it easier to breath and also provide room for the tongue to stick out.

ZQuiet uses a hinge which acts link a spring. This hinge helps keep it open beyond that of fixed piece mouthpieces.

What is ZQuiet made Out of?

It's made of medical-grade plastic which is designed for FDA compliance. It does not contain latex or BPA. It's made of a non-toxic thermoplastic elastomer compound.

How long will ZQuiet last me?

This depends on the individual, but it can last many months of repeat usage.

Am I able to breathe through my mouth while wearing ZQuiet?

Yes, you can breathe naturally through your nose and mouth when using it.

What is the 2-Step Comfort System?

ZQuiet provides two (2) unique mouthpieces designed to stop snoring aids.

One if less further forward ("Size A" is printed on it) and the other is more further forward (it doesn't have a size marking printed on it).

Can I open and close my mouth while wearing ZQuiet?

Yes, it features a "Living Hinge" which allows for naturally opening and closing your mouth while you wear it. Many people are able to talk or drink while wearing it.

How long does it take to get used to ZQuiet?

When you start to wear it, or any snoring mouthpiece for that matter, there is a bit of an adjustment period. This is because your jaw is accustom to a specific bite and position. When you change its position, while wearing a snoring mouthpiece at night for several hours, it may feel uncomfortable. Fortunately, this usually goes away within a few days or a week of wearing it.

What if ZQuiet doesn't work for me?

There's a 60-day trial period during which, you can return it as long as you get an RMA. You will want to make sure you have been able to wear it all night for at least a week before returning it. This will ensure you have properly evaluated it.

Which version is best to start with?

You should start with "Size A" because it is less further forward and is more likely to be comfortable.

You can use the other version of the device if you still notice snoring or want to know if it will be more comfortable than "Size A".

Does ZQuiet work for men and women?

Yes, ZQuiet can work for both men and women. Each of the devices can fit any adult's mouth.

What does ZQuiet feel like?

ZQuiet is made of a soft material which can bend. It feels soft and flexible but hard enough to stay in place while wearing it.

Patient Results

Actual Patient Results From Using ZQuiet

Note: these results were recorded using SnoreLab.



Night 1:


Night 2:


Night 3:


These results indicate that the patient had reduced snoring after wearing ZQuiet. The patient still had some snoring but it was reduced, it was not as loud and did not occur as often. It should be noted that the patient did not use any nasal strips while sleeping so some of snoring noise which was recorded could have been from obstruction in the nose.

Patient Feedback

A patient responded about their experience using ZQuiet for the nights they tested it:

  • Each morning, the patient said they woke up with some discomfort between the lower front teeth and lip.

    • The patient said that after they woke up, they would remove the device because it was uncomfortable.

    • One morning, the patient said that the discomfort and soreness they felt was bad enough to wake them up.

  • The patient said they did not notice any discomfort from ZQuiet when they went to sleep, they only experienced discomfort after wearing it all night.

  • The patient said that during the day, they felt a dull numbness in the same spot they noticed the discomfort in.

  • The patient mentioned they wore ZQuiet on consecutive nights despite the slight soreness they experienced.

  • The patient's results were from three (3) consecutive nights of wearing ZQuiet.

Actual Patient Oxygen Saturation While Using ZQuiet

While a patient was wearing ZQuiet, they wore a pulse oximeter, which measured how much oxygen was in their blood. These results indicate that the patient was able to get sufficient oxygen at night and that ZQuiet did not restrict their breathing.

Note: oximeter used in recording was the CMS50E

Fitting Process

How do you fit ZQuiet?

ZQuiet does not require any custom fitting or impressions to your teeth. Simply remove it from the supplied case and insert your teeth into the open channels with the “V” notch pointing upward. The resilient hinge keeps the device firmly in place.

You can trim it with small scissors to improve the fit and comfort you get from it. After you trim it, you should use a fingernail file or emery board to smooth any rough edges. This will help prevent irritation to your gums that could results from cutting the device.

Company Info

Is ZQuiet BBB Accredited?

Yes, ZQuiet has been BBB accredited since 2014 and currently has an A+ rating. (see BBB listing)

Who owns ZQuiet and how did the company start?

ZQuiet was co-founded by Daniel A. Webster in 2008. He sought a solution to his snoring problem after his wife informed him about her difficulty sleeping around his snoring. Webster tried surgery which was ineffective, painful and also not covered by insurance.

Daniel Webster found success after a dentist recommended a custom snoring mouthpiece. From there he began marketing ZQuiet on TV as a way to save relationships. ZQuiet is marketed at being a low cost introductory snoring solution.

Where can I buy ZQuiet?

Official website: www.zquiet.com

What size ZQuiet do I need?

When choosing a size for ZQuiet or any similar mouthpiece, the right fit is crucial for both comfort and effectiveness.

  • Comfort Size #1: This size advances the jaw slightly and is intended for those with a mild snoring issue or individuals trying a mandibular advancement device for the first time.

  • Comfort Size #2: This size advances the jaw further and is meant for those with a more pronounced snoring issue.

For many people, the company recommends starting with Comfort Size #1 to get accustomed to the feeling of bed again. If the snoring continues or is not sufficiently alleviated, then transitioning to Comfort Size #2 might be more effective.

Can I buy ZQuiet on Amazon?

Yes, ZQuiet is now sold on Amazon. You can also get it from their official site because it is a medical device.

Does ZQuiet Hurt Your Teeth?

ZQuiet, like other mandibular advancement devices (MADs), is designed to shift the position of the jaw forward slightly to open the airway and reduce or eliminate snoring.

One difference between ZQuiet and boil-and-bite mouthpieces is that ZQuiet doesn't use an impression of your teeth. If you are looking for a boil-and-bite mouthpiece, check out SnoreRx.

When used correctly and for the intended purpose, these devices are generally safe. However, there are potential concerns and side effects to be aware of:

  1. Tooth Discomfort: Initially, some users report mild discomfort or a feeling of pressure on their teeth. This sensation typically lessens with continued use as one gets accustomed to the device.

  2. Bite Changes: There is a potential (though rare) risk of long-term bite changes with prolonged use of MADs. Some users have reported a temporary change in their bite when they wake up, but this usually corrects itself shortly after removing the device.

  3. TMJ Symptoms: If you already have issues with your temporomandibular joint (TMJ), using a MAD might exacerbate those symptoms. It's crucial to discuss any TMJ problems or concerns with a dentist or doctor before using such devices.

  4. Gum or Dental Irritation: Any device in the mouth has the potential to cause irritation to the gums or teeth, especially if it doesn't fit correctly.

  5. Oral Hygiene Concerns: Proper cleaning is essential to prevent bacterial growth, which could negatively affect oral health.

  6. Wear and Tear: Over time, MADs can experience wear and tear, potentially leading to cracks or breaks in the device. Regularly inspecting and replacing the device as necessary is crucial.

To minimize risks:

  • Consultation: Before starting with any oral device, it's advisable to consult with a dentist or doctor, especially if you have dental work, TMJ issues, or other oral health concerns.

  • Follow Instructions: Always follow the manufacturer's instructions for fitting, cleaning, and using the device.

  • Monitor: Pay attention to any changes in your oral health or bite and consult a professional if concerns arise

  • Verity Thomson August 21st, 2022

    I used ZQuiet No.1 for a few nights and it reduced my Snore Lab snore score from 27 to 11 and then continued to lower the snore score down to 5, but after about 5 days it stopped working and my snore score is higher than ever (40+). Unfortunately the ZQ No.2 is too big for my mouth and doesn’t stay in. I’m really disappointed that it seems to have stopped being effective so soon. Any ideas?

  • Sandra August 25th, 2023

    Was I supposed to receive both sizes in my kit? I received only the size A.
