Based in California, the PureSleep Company has produced its flagship mouthpiece for over a decade. The PureSleep Mouthpiece was designed by a dentist and an ear, nose, and throat specialist. PureSleep focuses on manufacturing this affordable anti-snoring mouthpiece, which is available without a prescription from the doctor or dentist.

The PureSleep Mouthpiece is the only product the company currently offers. This mouthpiece is a plastic resin-based mandibular advancement device (MAD) designed to reduce snoring. It comes in one size, but it offers two customizable features with its boil-and-bite design and adjustable bite preference settings.

We’ll cover what you need to know to decide if this anti-snoring device is right for you, including materials, customization options, pricing, performance, and customer service policies.

PureSleep Mouthpiece Review Breakdown

Like other MADs, the PureSleep Anti-Snoring Mouthpiece prevents snoring by pushing the jaw forward to keep your upper airway unobstructed during sleep. Cleared by the FDA as a class II medical device, the PureSleep is sold over the counter without the need for a prescription from your doctor.

The PureSleep is made with two different BPA- and latex-free plastics:

  • A soft, moldable inner layer
  • A firm, supportive outer shell

Unlike many other over-the-counter MADs, the PureSleep offers two levels of customization. First, when assembling, you can choose between three different jaw advancement settings for a standard bite, overbite, or underbite. Second, the PureSleep has a boil-and-bite design that allows you to customize the device to fit to the shape of your mouth.

As a result, the PureSleep is suitable for a wide range of sleepers with different bite styles and mouth sizes. Its low price-point when compared to other MADs makes this device worth considering if you’re looking to reduce your snoring on a limited budget.

Materials and Options

The PureSleep Anti-Snoring Mouthpiece is made with two types of plastic resin. The inner material is a soft, moldable plastic. This moldable layer sits in an outer shell made from a more rigid plastic. Both materials are dental-grade and free of both BPA and latex.

The PureSleep Mouthpiece comes in a single, universal size. However, the device’s design allows users to achieve an adjustable, at-home custom fit. The upper and lower parts of the device can be assembled in three different configurations depending on your bite (standard, underbite, or overbite). The fitting process is slightly complicated, but it should result in an accurate fit when done correctly.

Once assembled, you can further customize the mouthpiece with the boil-and-bite method. The soft, inner material is heat-sensitive and can be softened in boiling water. After the device has cooled slightly, you bite down on the guard to create a customized impression of your teeth.

While the PureSleep offers initial adjustability, you cannot readjust it after assembly. You can re-boil the mouthpiece up to three times to optimize the interior fit.

Mouthpiece Performance

When choosing an anti-snoring mouthpiece, it’s important to consider how it will perform in the context of your unique needs. The PureSleep is a mandibular advancement device (MAD) that holds your jaw in a forward position to help prevent snoring. We’ll highlight what makes the PureSleep stand out from similar anti-snoring devices.

PureSleep Mouthpiece

Is the mouthpiece adjustable?

The PureSleep Mouthpiece is adjustable initially. The mouthpiece is shipped in two pieces that must be snapped together. When assembling the mouthpiece, you can choose one of three settings based on your bite pattern (standard, underbite, or overbite). While this allows for initial adjustability, the PureSleep's design does not allow for ongoing readjustments once it has been assembled.

How long will the mouthpiece last?

The PureSleep Mouthpiece is expected to last 4 to 12 months. Mouthpieces worn every night typically last between 6 months to 2 years depending on the construction and materials used. However, if you grind your teeth, you can expect the mouthpiece to wear out more quickly.

How do you clean it?

You can use a toothbrush and toothpaste or an effervescent denture tablet to scrub and sanitize the PureSleep Mouthpiece. PureSleep recommends only using its device on clean teeth. The device comes with a storage case to protect it when not in use.

Does it require a prescription?

The PureSleep Mouthpiece has been cleared by the FDA to treat snoring and does not require a prescription. However, if you suffer from sleep apnea or another respiratory disorder, speak with your doctor before using the PureSleep Anti-Snoring Mouthpiece.

How Does the PureSleep Mouthpiece Work?

The PureSleep Mouthpiece prevents snoring by holding your lower jaw in place. Snoring during sleep is quite common. It is caused by vibrations in a constricted airway. When you sleep, the muscles in your upper airway relax. As a result, the lower jaw and base of the tongue tend to sink back, which can restrict the space in your throat. Air moving through this tight space causes vibrations in the soft tissue, creating the sounds of snoring.

To reduce snoring, anti-snoring mouthpieces work to keep your upper airway open and clear. The PureSleep Mouthpiece molds to the shape of your teeth and holds your jaw in place relative to your upper teeth. This helps prevent your jaw, tongue, and surrounding tissues from sinking back and restricting your airway.

The wider space in your upper airway helps improve airflow as you breathe and should reduce the sound of snoring. The PureSleep is suitable for sleepers who breathe through their mouths, although our testers found that the small holes in the device did not allow for immense airflow.

It can be custom-fit at home and adjusted to the jaw position that you prefer. However, you should not use the PureSleep if you have a serious respiratory disorder, central sleep apnea (CSA), braces, full dentures, or a history of temporomandibular joint disorder (TMD).
