ZQuiet was founded in 2008 with the debut of the ZQuiet Anti-Snoring Mouthpiece. The company has since gone on to produce an entire line of anti-snoring and noise-canceling products, including mouthpieces, earplugs, nasal breathing aids, and positional sleeping aids.

The ZQuiet Mouthpiece is produced in two sizes, each one advancing the jaw to a different extent. The unique living hinge design has a low profile, with a universal fit that is intended to be suitable for both men and women. The ZQuiet Mouthpiece is made of a soft thermoplastic polymer for added comfort.

ZQuiet currently offers two mouthpiece models, the original ZQuiet Mouthpiece and the ZQuiet Firm Mouthpiece. We’ll focus on the original ZQuiet Mouthpiece. We’ll discuss its materials, measurements, performance, price, and company policies to help you determine if this mouthpiece is right for you.

ZQuiet Mouthpiece Review Breakdown

Anti-snoring mouthpieces have become popular solutions to snoring that are generally more affordable and less invasive than other options. The ZQuiet Mouthpiece is an over-the-counter mandibular advancement device (MAD) that uses clinically proven technology.

The ZQuiet Mouthpiece is designed to allow the user to move their jaw and breathe naturally. It can be used out of the box, and does not require a fitting process prior to use. The ZQuiet Mouthpiece is manufactured in the United States.

The mouthpiece is suitable for those who want a style that is easy to use, as it has a universal fit and does not require boiling or custom molding prior to use.

Materials and Options

ZQuiet includes two sizes with each mouthpiece order: one that advances the lower jaw 2 millimeters forward and another that advances the jaw 6 millimeters forward. Both are classified as MADs. The company recommends starting with the 2 millimeter size, and advancing to the 6 millimeter size in the event that your snoring continues.

The mouthpiece is made of a flexible, medical-grade thermoplastic polymer. It has undergone extensive consumer testing and is FDA cleared. Additionally, it is free of BPA, silicone, and latex.

Mouthpiece Performance

One of the ZQuiet Mouthpiece’s standout features is the wide range of jaw movement that users are afforded due to its flexible, lightweight design. The ability to use it immediately without any molding or adjustments makes it an appealing option to those who are seeking convenience.

When evaluating a mouthpiece, shoppers may want to consider adjustability, longevity, cleaning, and prescription requirements.

Is the mouthpiece adjustable?

The ZQuiet Mouthpiece is not adjustable. Sleepers can decide which of the two sizes suits them better, based on how much jaw advancement is needed.

If the mouthpiece is too large, users have the option of trimming the edges slightly with small scissors. Once trimmed, the mouthpiece edges should be filed with an emory board.

How long will the mouthpiece last?

The mouthpiece is designed to last for at least a year. However, its lifespan will depend on usage and care. The company recommends replacing the device every 4 to 6 months as needed.

Those who clench or grind their teeth at night should replace the mouthpiece every 3 months. The ZQuiet Firm Mouthpiece may be preferable for these users, as it is made with a more rigid material and a stronger hinge.

How do you clean it?

The ZQuiet Mouthpiece can be cleaned using warm water, mild soap, and a toothbrush. Using toothpaste to clean the device is not recommended, as it may damage or discolor the surface.

ZQuiet also produces a cleaning solution that can be used. The device can be scrubbed with the solution and a toothbrush before rinsing. This formula is chlorine- and persulfate-free.

Does it require a prescription?

No prescription is needed to purchase the ZQuiet Mouthpiece. Shoppers with medical concerns or dental work should consult with their doctor or dentist prior to use.

How Does the ZQuiet Mouthpiece Work?

Snoring results from the tongue and soft palate becoming relaxed and partially blocking the airway. Common causes of snoring include alcohol consumption, being overweight, and sleep position.

The ZQuiet Mouthpiece works similarly to other MADs by advancing the lower jaw to open the airway, reducing tissue vibration in the back of the throat.

The ZQuiet Mouthpiece differs from other mouthpieces due to its low profile and hinged design, making the mouthpiece less intrusive than similar products that use a hard plastic outer shell. This allows the user a wider range of jaw movement and more airflow.

The device is designed to be suitable for people in any sleeping position. While the ZQuiet Mouthpiece is intended to fit most people comfortably, it is not adjustable. Those who prefer more customization may want to consider other options.
