PureSleep Mouthpiece Review

Half of us snore from time to time but roughly one-fourth of people snore on a nightly basis. Occasional snoring is tolerable, but if you’re a chronic snorer (or sleep next to one), you probably want relief to your nighttime noise-making.

Anti-snoring mouthpieces are effective with about 90% of snoring cases. Some causes of snoring include allergies, congestion, illness, alcohol, excess weight, or chronic sleep apnea which itself has a variety of causes.

Some serious conditions may require a CPAP, but other snoring is alleviated by an over-the-counter device. PureSleep is a Mandibular Adjustment Device (MAD) that helps many users relieve snoring and get a better night’s sleep.

Check out the Tuck review and ranking of this cost-effective anti-snoring mouthpiece. We look at materials and design, side effects and effectiveness, customers reviews, and our own experts’ ranking of how well it works.

What is PureSleep and How Does it Work?

For chronic snorers, an anti-snoring device can be life-changing. You can choose from two types of over-the-counter devices to relieve or stop snoring. One type restrains the tongue and the other shifts the tongue.

A Mandibular Adjustment Device (MAD) helps stop snoring by pushing the lower jaw forward where the tongue muscle attaches. That keeps it from moving back into the airway and causing snoring.

A Tongue Retaining Device (TRD) also keeps the tongue from moving into your airway but it does so by holding the tongue down, so it cannot shift while you’re sleeping on your back.

PureSleep is a MAD that adjusts the jaw forward to ensure your tongue can’t fall back in your airway, won’t impede your breathing, and should decrease or eliminate snoring. The device is customized using the boil-and-bite method like many other MADs.

How PureSleep differs from other anti-snoring mouthpieces

PureSleep has a more customized bite setting than other similar over-the-counter anti-snoring mouthpieces. Based on three types of bite (standard, underbite, or overbite), you pre-adjust the mouthpiece and then it’s further customized with the boil and bite method.

Based on aggregated customer data and our own research, we found that PureSleep works well for a wide range of snorers. The process to customize the mouthpiece is more involved than other MADs on the market and it’s FDA-approved as a Class II medical device for snoring treatment.

Critical Data on Mandibular Advancement Devices

Mandibular Advancement Device (MAD)

Material: These devices can be silicon resin or polymer (plastic)
Breathing Function: MADs help improve breathing, but some offer more airflow than others
Side Effects: Jaw stiffness or discomfort, sore teeth (more common with pre-existing dental problems), bite changes or disruption, dry mouth, and excess salivation
Bruxism aid?: MADs may help with night tooth-grinding
Denture-friendly?: Dentures and MADs are not compatible, but one study suggests trying modified dentures designed to work as a MAD. Also, consider a TRD
Expected Lifespan: MADs can last from 12-24 months but varies based on whether you tooth grind, the quality of materials and other factors
Average Cost: Over-the-counter MADs cost between $50-150 and custom anti-snoring mouthpieces can cost $500-1,000


Product Specifics

Here’s a look at the PureSleep anti-snoring mouthpiece and whether it might be a good solution for you. You’ll see the components, how it helps relieve snoring, and how effective it is.


The PureSleep device is a patented Mandibular Advancement Device (MAD) that reduces or eliminates snoring by pushing the jaw forward to keep the tongue from blocking the airway.


The PureSleep anti-snoring device contains two types of resin. The outer plastic is a bit harder, and the inner plastic where you set the bite is softer. The materials are BPA and latex-free.

Sizes available:

It is one size fits all and some reviewers comment that the mouthpiece feels a bit small.


There are multiple adjustment settings based on your bite size. You click the mouthpiece together based on recommended settings, then proceed with boil-and-bite customization.

Ability to re-adjust:

No, there is no readjustment to PureSleep after the initial boil-and-bite fitting. You can re-boil up to three times to optimize the initial fit, but from there, it’s not changeable.


For about 80-85% of confirmed users, PureSleep lessens or eliminates snoring. This is a bit lower than the typical 90% effectiveness rate of MADs in general.

Side effects:

PureSleep wearers often experience an initial soreness of teeth and gums or jaw discomfort like that of adjusting to braces at first.

Ease of breathing:

Although the device does improve breathability by preventing tongue blockage, the air holes in the device itself are relatively small (3 mm), so there’s not immense airflow for mouth breathers.

Ease of cleaning:

PureSleep recommends that you only wear the device over clean teeth and clean the mouthpiece with toothpaste and toothbrush or using an effervescent denture tablet.

Denture friendly:

You should not wear PureSleep over full dentures, but unlike with other MADs, the company says it’s okay to wear with partials, implants, and other permanent dental work.

Bruxism concerns:

PureSleep will block tooth grinding while you sleep but if you do grind at night, it will reduce the life expectancy of the MAD.


Like many other MADs on the market, there is a return period, but not a warranty. With PureSleep, you can return the mouthpiece within 30 days for a refund if you bought it outright, less the shipping charge. If you bought on the trial option, you must return within 30 days to avoid the charge.


PureSleep estimates their anti-snoring mouthpiece should last for six to 12 months, but if you’re a tooth grinder, it might not last as long.


There are two options. One, you pay $9.95 and are sent two mouthpieces. If you keep it, they charge you $59.90. Alternately, you can pay $59.90 upfront for one PureSleep device.

Fitting the PureSleep Mouthpiece

PureSleep has a more extensive fitting process than other similar MADs. The mouthpiece comes in two pieces, and you must click it together according to preference before you proceed to the bite fit. The settings vary by 1, 3, and 5 mm.

You will also need to assemble:

  • A pan of water
  • A spoon or tongs
  • Cuticle scissors

Determine if you have a typical bite, mild underbite, severe underbite, or drastic overbite. There’s an assembly setting for each. With the drastic overbite, you must flip the device upside down for fitting and usage. There’s some decision making involved.

To custom fit your PureSleep mouthpiece:

  1. Figure out the bite setting you need and click it together (choose wisely, as this aspect can’t be changed).
  2. Boil a pot of water and turn off the burner.
  3. Submerge device for 60 seconds.
  4. Scoop it out with tongs or a spoon and let it cool down for 15-20 seconds.
  5. Place the device in your mouth and, while holding your lower jaw as far forward as you can without it being aggressively uncomfortable, bite down.
  6. Bite and hold with jaw forward for 45 seconds – it will feel warm in your mouth.
  7. Cool it under running water.
  8. Trim any overflow material that might rub against your gums and mouth with small scissors.
  9. You can re-boil and refit three times to ensure you get the proper impression, but you can’t click it in a different position.

There’s an instructional video worth watching that helps determine how to recognize your bite type and how to click the device together before molding it.

What Do Customers Think of PureSleep?

Many customers report an immediate lessening or end to snoring with PureSleep. Many users report that the device causes initial jaw soreness and the company recommends buyers give it a three to five-day break-in window or to build up to wearing it all night over a period of several days.

PureSleep is rated A+ with the Better Business Bureau. There are some older complaints and most center around exceeding the 30-day return window. The company seems to be insistent about holding buyers to the 30-day limit in its terms and conditions.

Common feedback from customer reviews include:

  • Good results for snoring cessation
  • Many customers report initial jaw soreness that eventually subsided
  • Good results at a reasonable price, but durability is a concern

Is PureSleep the Best Option for You?

Typically, MADs reduce snoring for about 90% of users. PureSleep has a slightly lower average effectiveness rating of about 85%, but results with any anti-snoring mouthpiece are highly subjective. If you want to try a cost-effective anti-snoring mouthpiece, this could be just the thing for you.

PureSleep might work well for you if:

  • Have dental implants or partial dentures that other devices won’t accommodate
  • Want to test-drive a MAD that’s in a lower price range

PureSleep is not recommended for:

  • Those with central sleep apnea, respiratory issues, and recent dental implants
  • People unwilling to adjust to the mouthpiece and work through some jaw soreness

Common complaints:

There are a few common complaints reported by some buyers. These issues may include:

  • Jaw pain and jaw clicking or locking
  • Some drooling that dissipates after the break-in period
  • Confusing website and a lengthy questionnaire before you can order
