ZQuiet Anti-Snoring Mouthpiece Review:
Our Guide to the Device

ZQuiet specializes in products designed to help people improve the quality of their sleep, including earplugs and nasal strips. The company’s flagship product is the ZQuiet Anti-Snoring Mouthpiece, a mandibular advancement device (MAD) made from a soft thermoplastic elastomer. By moving the lower jaw slightly forward, the mouthpiece helps prevent collapsed airways that contribute to snoring

The dentist-designed, FDA-cleared mouthpiece doesn’t require molding, so it is ready to use right out of the box. It’s also fairly inexpensive compared with many anti-snoring treatments. 

While the ZQuiet device doesn’t require a prescription, speak with your doctor if you have concerns about your snoring, as it could be a sign of sleep apnea or another medical condition. You can also take our snoring quiz to better understand what’s causing your snoring.

ZQuiet Mouthpiece: Our Verdict

The ZQuiet Mouthpiece is lightweight and comfortable, thanks to its soft thermoplastic elastomer material. It also features a flexible hinged design that enables greater jaw movement than the typical anti-snoring mouthguard.

Another bonus is that the mouthpiece can be used immediately since it doesn’t require custom molding. The flip side to this, however, is that it might not comfortably accommodate every person’s jaw size. You can trim and file down the edges to make it slightly smaller, though. 

Each kit includes two sizes that advance the lower jaw to varying degrees, allowing users to experiment with what angle works best for their anatomy and snoring level.

Pros and Cons

The ZQuiet Mouthpiece comes in a universal size that doesn’t require custom fitting or molding. Its lightweight design is made from a soft thermoplastic elastomer that gently rests over your teeth. Since the mouthpiece is nonadjustable, it might not fit very small or very large jaws.

  • Soft and pliable
  • Ready-to-use design doesn’t require professional fitting or molding
  • Edges can be trimmed and filed for a more customized fit
  • May not be durable for people who grind their teeth 
  • Aside from trimming the edges, the mouthpiece isn’t adjustable
  • Sleep trial has a $9.95 fee

Who Should Use the ZQuiet Mouthpiece?

The ZQuiet Mouthpiece is designed to eliminate or reduce simple snoring, which is snoring that’s not caused or accompanied by more serious conditions like obstructive sleep apnea. The ZQuiet device may also help people who grind their teeth by keeping their upper and lower jaws separated. 

The ZQuiet device may worsen symptoms for people who experience dry mouth or excessive drooling during sleep. The mouthpiece should not be used by people who wear dentures or those who have gum or jaw conditions or loose teeth. It’s also not recommended for people who have recently undergone dental procedures.

Speak with a physician if your snoring is severe or if you have concerns that it may be a symptom of a more serious health problem.

Who Is It Ideal For?
Who Should Avoid It?
  • The ZQuiet device is designed to eliminate or reduce simple snoring
  • The mouthpiece may help sleepers who grind their teeth or clench their jaw
  • The lightweight, flexible design caters to those who dislike the feel of a tongue-retaining device (TRD)
  • The mouthpiece may worsen symptoms for sleepers who drool or experience dry mouth
  • The ZQuiet device is not a substitute for CPAP therapy for people with obstructive sleep apnea

How Does the ZQuiet Mouthpiece Work?

Snoring occurs when a sleeper breathes through blocked airways caused by the tongue falling back in the throat or collapsed soft tissues. By moving the lower jaw forward, the ZQuiet Mouthpiece helps keep the tongue and soft palate from obstructing airways. People who grind their teeth may also gain relief since the mouthpiece serves as a barrier between the upper and lower jaws.


The soft material of the ZQuiet Mouthpiece rests over the teeth while allowing users to move their jaw freely. The hinged design offers flexible comfort, though the one-size-fits-all sizing may be too obtrusive for people with small mouths. The device is compatible with all sleep positions. 

Price and Size Options

The ZQuiet Mouthpiece is nonadjustable and ready for immediate use. Each kit includes two sizes. One mouthpiece moves the jaw forward 2 millimeters, while the other advances the jaw 6 millimeters. ZQuiet recommends starting with the smaller size and progressing to the 6-millimeter model if snoring persists. 

The ZQuiet Mouthpiece starter pack is a good value option, as it includes two mouthpieces, a storage case, and free shipping for U.S. shoppers. The company also offers discounted bundles and promotional pricing. 


ZQuiet’s mouthpiece doesn’t require custom fitting or molding. The soft plastic rests on your teeth while gently advancing the lower jaw. While not adjustable, users can modify the fit somewhat by trimming the edges. 


The mouthpiece is made from a medical-grade thermoplastic elastomer with a metal-free hinge. The device has been cleared by the Food and Drug Administration for use as a Class II medical device and doesn’t contain latex, silicone, or BPA. 


ZQuiet recommends replacing the device every four to six months, though with proper care it may last up to a year. People who grind their teeth may need to replace it more frequently. However, the company also makes the ZQuiet Firm Mouthpiece. Featuring a more robust hinge, the firmer mouthguard is designed for greater durability.

Cleaning and Maintenance

The mouthpiece can be cleaned using a toothbrush with warm water and dish soap. ZQuiet cautions against using toothpaste, alcohol-based cleaners, or abrasive chemicals, as these may cause surface wear and discoloration. Alternatively, the company makes a cleaning solution that takes one minute to disinfect. ZQuiet recommends cleaning the mouthpiece after each use. 

Where Can You Get the ZQuiet Mouthpiece?

The ZQuiet Mouthpiece is available from the manufacturer in the U.S. and select international locations. It is also sold by third-party retailers, but shoppers should note that their shipping and return policies may differ.

Trial, Warranty, and Shipping Policies


The ZQuiet Mouthpiece can be purchased through the company’s website and from online retailers such as Amazon and Walmart. International distributors are listed on ZQuiet’s website.

Prescription Requirement

A prescription is not needed to buy the mouthpiece. The universal size doesn’t require professional molding or digital imaging.


The ZQuiet Mouthpiece includes free standard shipping within the U.S. Most standard orders arrive within 7 to 10 business days. Expedited shipping is available for an extra fee.

Trial and Return Policy

ZQuiet offers an optional 30-day trial for a $9.95 fee. The full purchase cost is automatically charged to customers if the mouthpiece isn’t returned during the trial period. The $9.95 fee is nonrefundable.


The mouthpiece includes a 60-night money-back guarantee. Customers can return the device for a full refund during this period. A return authorization is required, and shipping and trial fees are nonrefundable.

ZQuiet Refills and Accessories

ZQuiet offers mouthpiece refills, auto-deliveries, and additional products for people who snore and those who sleep next to them.

ZQuiet Clean Oral Appliance Brush

ZQuiet makes an inexpensive cleaning brush for its mouthpiece and other oral appliances. It has a large brush head and can be paired with the ZQuiet Clean Anti-Bacterial Cleaning Solution.

ZQuiet Breathe Nasal Breathing Aid

This winged nasal strip is worn over the nose and is intended to reduce snoring by opening nasal passages. It has a modest price-point, making it more approachable than many anti-snoring treatments.

ZQuiet Earplugs

Available in large and small sizes, the ZQuiet Flex-Fit Earplugs are made of silicone. The ZQuiet ErgoSoft Earplugs are composed of softer rubber but only come in small.

If you’re having trouble deciding, the company offers the Earplug Discovery Set, which comes with both sizes of the Flex-Fit and a pair of the ErgoSoft.

ZQuiet also sells the QuietOn 3 sleep earbuds on its website, though these pricier noise-canceling earplugs are made by the Finnish company QuietOn Ltd.
