Invented by a dentist and a doctor over a decade ago, the PureSleep Anti-Snoring Mouthpiece is designed to hold the lower jaw forward to reduce snoring. While many similar mandibular advancement devices (MADs) require a prescription, the PureSleep gained over-the-counter clearance from the Food and Drug Administration in 2019. Its customizable design, years of widespread usage, and reasonable price-point make it an appealing option for many chronic snorers.

We’ll review the pros and cons of the PureSleep Mouthpiece, exploring how it works, who it’s best for, and where to buy it.

PureSleep Mouthpiece: Our Verdict

The PureSleep Mouthpiece is designed to draw the lower jaw forward, thus opening the back of the throat and upper airway for better airflow.

The PureSleep’s success as an anti-snoring aid is contingent on properly fitting it to your mouth. The device has three adjustable settings for standard bites, overbites, and underbites. Once you assemble the upper and lower parts of the device to your preferred setting, the custom fitting process involves boiling and then biting the mouthpiece with your lower jaw thrust forward. The mouthpiece can be reboiled up to three times. After this initial fitting, no further adjustments can be made. The company includes an illustrated instruction manual to help you get a good fit.

While the device’s air holes allow for airflow, they are relatively small. This could be limiting for some people who breathe through their mouth. Sleepers may also notice jaw soreness in the morning, but most find this to be less of an issue with regular use.

Pros and Cons

Different bite type settings plus a boil-and-bite setup allow for a more customized fit and increased effectiveness, but sleepers may still find they need a significant adjustment period to alleviate initial jaw soreness when using the PureSleep Mouthpiece.


  • Upper and lower parts can be adjusted for several bite settings, accommodating underbites and overbites
  • Customized fit after proper boil-and-bite setup
  • Free shipping and returns within 60 days of purchase


  • Morning jaw pain may lead to a longer adjustment period
  • Not recommended for those with chronic asthma, emphysema, COPD, or other breathing disorders
  • Can’t be used with braces, full dentures, or other sleep appliances

Who Should Use the PureSleep Mouthpiece?

The PureSleep Mouthpiece may be a good fit for sleepers with mild to moderate snoring. Keep in mind that it isn’t approved as a treatment for obstructive sleep apnea. Consult a doctor if you are concerned that your symptoms may relate to an underlying medical condition or if you have questions about whether a MAD device like the PureSleep is right for you.

Who Is It Ideal For?

  • Sleepers looking to alleviate mild to moderate snoring
  • Adults in good physical and oral health
  • Those with underbites, overbites, or standard bites

Who Should Avoid It?

  • Those with chronic breathing issues, respiratory disorders, or sleep apnea
  • Sleepers with recent dental implants, loose or weak teeth, or symptoms of temporomandibular joint disorder
  • Sleepers with braces, dentures, or other dental appliances

How Does the PureSleep Mouthpiece Work?

The PureSleep Anti-Snoring Mouthpiece features two plastic resin trays for your upper and lower jaw. These trays click together, allowing sleepers to match their bite type to one of three settings. Sleepers can then optimize the fit by boiling and biting down on the appliance, bringing the lower jaw as far forward as is comfortable.


The PureSleep Mouthpiece is an FDA-cleared Class II medical device designed to treat snoring. Once inserted at night, the PureSleep device holds the lower jaw forward to open the airway. A wider airway prevents the soft tissues of the throat from vibrating with each breath, allowing air to flow more freely. 

Price and Size Options

The competitively priced PureSleep Mouthpiece costs less than many MADs on the market. Your purchase includes one mouthpiece, a storage case, and an illustrated instruction booklet. The device comes in a single size with a customizable fit. 


The PureSleep Mouthpiece consists of upper and lower components that snap together. Sleepers can select a setting based on their bite type, then boil and bite the resin for a customized fit. Note that the device must be allowed to cool slightly before fitting it in your mouth. The PureSleep can be boiled up to three times. After that, no further adjustments are possible.


The PureSleep is made from two types of resin: a harder outer resin and a softer inner resin that makes it possible to set the bite. Both resins do not contain BPA and are latex-free.


Although the durability of the PureSleep device is somewhat variable, sleepers can expect the mouthpiece to last 4 to 12 months. Those that grind their teeth may need to replace the device sooner.

Cleaning and Maintenance

The device should be cleaned regularly with a gentle toothbrush and toothpaste or by soaking it in water with an effervescent denture tablet. For best results, only wear the PureSleep with clean teeth.
