SleepTight Mouthpiece Review
UPDATED Mar. 2018


This SleepTight Mouthpiece review will show you not only how to solve your snoring problem, but also how to manage sleep apnea, a sleep disorder that is characterized by pauses in breathing during sleep. Keep in mind, though, that only a few self-fitted mouthpiece manufacturers can currently say that they are able to treat sleep apnea – and SleepTight is one of them.

What Is SleepTight?


SleepTight is a new arrival to the snoring mouthpiece industry, as it was introduced to the public in the middle of 2014. The product is a boil-and-bite style Mandibular Advancement Device (MAD) that can be custom-fitted in the comfort of your home. MADs are mouthpieces that gently hold the lower jaw forward in order to prevent snoring.

When holding the jaw forward, muscles and loose tissues that surround the airway tighten up and the airway opens. There’s also a tighter, less restrictive airway that will not vibrate, preventing snoring from occurring. MADs have been used for quite some time now and a number of medical studies have confirmed that these aids are quite effective.

How Is It Different?

SleepTight Mouthpiece Review

This particular MAD features a never before seen dual laminate design which helps to capture an almost identical impression of the teeth. There’s a flexible plastic material at the core of this device that is similar to what is used in other boil-and-bite mouthpieces on the market. However, the upper and lower trays also feature plastic inlays, each thick about 1.5 mm. Both inlays feature a series of ridges which deliver additional material to each tooth during the fitting process.

After the device is heated, the inlays enter a gel-like state, flowing perfectly into the cavity of each tooth. The overall shape of the mouthpiece remains unchanged due to the core material that is used. This is a pattern that SleepTight have invented. They are the proud owners of the intricate design which is revolutionary in the industry.

Like other mouthpieces, SleepTight has its limitations when it comes to life expectancy. Keep in mind that this particular contraption will last slightly longer than your usual MAD. This is partly due to its design and silicon base. Although the lifespan of these devices may be shortened due to cleaning, maintenance, and teeth grinding, this particular product should last anywhere from 6 to 30 months, which is some 6 months longer than your average MAD.

Fitting The Mouthpiece

Like all the best anti-snoring mouthpieces, SleepTight needs to be molded to perfectly fit your mouth before you start using it. The process is simple and quick and once completed, you will have a device that is customized to fit your jaw and teeth. This maximizes the device’s efficiency.

To fit the SleepTight device, you will need some water, a pot, a container, a spoon, preferably slotted, or kitchen tongs, and a timer. Put some water in the pot and bring to a boil. You will need some two quarts or just enough water to cover the device completely. Once the water starts boiling, remove it from the stove and allow it to cool for exactly 60 seconds. Longer than that, the water will be too cool to make a good impression. Shorter than that, the heat may damage the material. Next, place the SleepTight mouthpiece into the water. You may need to hold the device down under the water with a utensil because it tends to float.

Keep the mouthpiece in the hot water for exactly three minutes. After that, take the mouthpiece out and check whether the edges have folded over. If they have, straighten them back to the original position. Place it in your mouth – on the lower teeth first – and bite down hard. Move your lower jaw slightly forward. Then use your fingers and tongue to mold the material against your teeth and gums. Keep it in your mouth until it reaches body temperature and finally place it in some cold water for the shrink fit, which completes the fitting process. Allow the device to dry. Do not rub it with paper towel or tissue. When it’s dry, place it in its protective container and keep it there until bedtime.


  • Bring some water to a boil, remove from heat and leave it for 60 seconds.
  • Place the device in the hot water for three minutes.
  • Place it in your mouth and bite hard to make an impression. Use your tongue and your fingers to press the device against your teeth and gums.
  • Put the device in cold water to harden.
  • Air dry the device.


SleepTight is not the cheapest solution for your needs but, as obvious from our SleepTight Mouthpiece review, it is well worth the price. In case you aren’t sure whether you like the device or if you’re one of those people who want to try out everything before they buy it, the company offers a 30-day trial. All you have to do is pay $9.95 and they will send you a mouthpiece.

If you are not satisfied with the device, you can return it and you will not be charged afterward. However, if you decide to keep SleepTight, your credit card will be billed for the full price of the product, which is $69.9.

  • It actually works
  • Easy to use
  • Great customer service
  • Fast delivery


  • Moderately high price
  • Takes time to get used to sleeping with a mouthpiece

Bottom Line

This SleepTight Mouthpiece review revealed a fantastic product that we like for a number of reasons – it’s easy to use, it’s extremely well designed, and it’s a proven technology in snore reduction. If the company had included a resettable adjustment technology, the device would’ve been perfect. Still, it’s a snoring solution that really delivers exceptional results.

    I thought it ludacris at first, but it actually does help, not 100% but it’s something. I could learn a proper song, though, now that I’m already at it.

    Having been struggling with severe snoring literally for decades, I’ve tried pretty much every device out there. Right now Im using Sleep Tight mouthpiece device and I got to say Im pretty happy with it. It took some getting used to as it does with every new device, after all it’s in the mouth and it’s all so sensitive in there. But my snoring is definitely improving. We’ll see how it performes over time but for now Im confident I have found the solution for my snoring issues.

    My hubby got me this mouthpiece a week ago because my snoring was getting really intolerable. He had been sleeping on the living room sofa for almost a month and now he’s back in our bed so that has to count for something, right!?

    SleepTight is my favorite new device. I did the fitting part in no time, it was really easy and after a night or two I got so used to it now I forget it’s even there. Of course my mouth still looks a bit weird from the outside but that’s a small price to pay for a good night’s sleep. I also think that SleepTight is pretty reasonably priced and I love the fact that it is FDA-approved. It just puts my mind at ease.

    Excellent snoring device, SleepTight is the best! It changed by life for the better.

    Sleep Tight is definitely better than my old anti-snoring mouthpiece, which wore off and almost stopped being useful. This one fits nicely and it’s not as uncomfortable as new mouthpieces tend to be in the beginning.

    Fitting the mouthpiece was actually quite fun but it’s not fun wearing it all night long. Just can’t get used to the idea of having a full mouth while sleeping.

    My snoring isn’t as bad as it used to be but it’s not gone either. Also, I drool quite a lot now, so I feel like I replaced one problem with another.

    Loved this snoring aid!

    Don’t expect any miracles! It works to some extent but it’s not great. I don’t snore as loud as I used to before using the device but I still snore. Not sure what to think of it – I’ll give it more time.
