Designed by a dentist who used to snore, the SleepTight has been custom-made for its demographic.

I’ve been snoring for a long time, but it got worse after I suffered an athletic injury that left me with a deviated septum.Not only did it put me through physical pain as well as emotional turmoil, but it also meant that some of the most popular anti-snoring products didn’t work for me. They weren’t designed for mouth breathers, or they weren’t effective at dealing with the kind of airway obstruction that happened to me at night. Finding the SleepTight was like stumbling on a miracle. Though it isn’t a flawless product, it works so well despite my nasal issues that it’s hard for me not to get a little excited as I talk about it.

Using the SleepTight (And Not Letting the Bed Bugs Bite)

Please forgive my enthusiasm in this SleepTight review, but I’m just so thrilled at being able to share an anti-snoring product that works for other people with deivated septums.

The Truth Behind Snoring

Snoring can be caused by many different factors, and in my case, it was started and exacerbated by my injury. But most people snore for a much simpler reason.

When you sleep, your throat muscles relax so much that they can actually cause an obstruction to your air flow. Your tongue can also roll back towards your throat and narrow the passageway even further. When oxygen struggles to get through, it vibrates against your tissue and creates sound. That’s snoring.

To stop snoring, you have to keep your airway open at night, but you can’t do this without help. You’re unconscious! Your throat muscles are going to relax no matter what.

This is where the SleepTight can save the day.

How It Works

The SleepTight is a mandibular advancement device (MAD) that holds your jaw at a certain angle while you sleep. Even when your throat expands, your airway will remain open because of the “advanced” position of your jaw and chin.

There are many MADs on the market, and they all function the same way. However, the SleepTight stands out from the rest for several reasons.

For starters, it was designed by an actual dentist. His name is Dr. Mike Williams, and he’s a certified member of the American Academy of Sleep Medicine.

Dr. Williams knows what it’s like to struggle with a snoring issue. He dealt with it for years, even undergoing surgery in an attempt to fix his nighttime breathing problems, but his efforts were in vain until he started experimenting with his own product designs. The result was the SleepTight.

The SleepTight can be fitted and customized in ways that other MADs can’t. It’s also much more durable than similar products of its type. If these things weren’t enough, it’s also a sleek and attractive mouthpiece that distinguishes itself from its ugly, bulky cousins on first sight.

Long story short, there’s a lot of reasons to love the SleepTight. Let’s talk about them one at a time.


The SleepTight is a mouthpiece that you put between your lips and wear overnight. As a former athlete, I found it a bit like a mouth guard, but your experience might be different.

The SleepTight is made with a special kind of double-laminate plastic that makes it much sturdier than the competition. This is especially remarkable since it’s also a “boil and bite” product that can be softened with hot water to customize its fit, but I’ll get to that in a minute. For now, rest assured that it’s a comfortable and flexible product.

Another great thing about the SleepTight is that it offers a wide range of motion. Some anti-snoring mouthpieces are so rigid that you can’t talk or drink water while you’re wearing them, but the SleepTight isn’t like that. It’s designed with a six-millimeter airway opening that will accommodate any kind of talking, breathing, drinking or swallowing.

I’d also be remiss if I didn’t talk about the attractive nature of the SleepTight design. While other MADs can look almost like children’s toys with their bulky pieces and searingly bright colors, the SleepTight is much more sophisticated. It’s sleek and compact, so it’s discreet. It’s transparent, so it won’t be an eyesore. It’s even designed as a single, streamlined mouthpiece instead of having upper and lower jaw trays clumsily stuck together.

If you’re looking for a snoring solution that won’t embarrass you just as much as the snoring itself, the SleepTight is what you seek.

How the SleepTight Mouthpiece Fits

One of the best features of the SleepTight is its ability to be customized to the exact shape of your mouth. Instead of having a sore jaw thanks to a “one size fits all” mouthpiece, you can mold the SleepTight to fit every single tooth.

It’s called the “boil and bite” method, and here’s how you do it:

1. Boil a cup of water. Let it sit for a minute so that it’s still hot but not actively bubbling.

2. Submerge the mouthpiece under the water. It will try to float to the surface, so keep it held down with a fork or a pair of tongs.

3.Remove the product from the water after 50-60 seconds. It should feel soft and malleable.

4.Put the product between your lips and bite down. Hold this pose for another 60 seconds.

5.There should be a nice impression of your teeth in the mouthpiece. If you’re satisfied with it, rinse it under cold water to re-harden the material and set the impression. If you don’t like the way that it turned out, put the mouthpiece back in the hot water and try again.

A nice thing about the SleepTight is that you can repeat this process four or five times before the material starts to degrade. Other “boil and bite” products limit you to 2-3 attempts, but thanks to the double laminate material of the SleepTight, it can be manipulated for longer periods of time before it starts to break down.

All of this translates to a mouthpiece that can be customized until it’s truly perfect for you.

Does this mouthpiece has flaws?

I’ve spent a lot of time talking about the advantages of the SleepTight. In the interest of fairness, let me share some of its disadvantages as well.

Its biggest problem is one that plagues many anti-snoring mouthpieces: excess salivation. Some people are more affected than others, so it’s not a given thing that the SleepTight will make you drool, but it’s something to consider.

Another issue is long-term maintenance. The SleepTight needs to be cleaned every morning after use. While you should do this with any mouthpiece thanks to the lingering effects of oral bacteria on plastic materials, it’s especially critical for the transparent SleepTight. You can’t hide anything with its see-through design.

The transparency can also cause staining problems if you don’t clean the SleepTight correctly. It’s recommended that you don’t use toothpaste or mouthwash, especially the kind that’s been artificially colored; it might rub off on the plastic. You’ll want to soak the mouthpiece in a special cleaning solution meant for dental devices to properly maintain it.

I don’t mean to make the cleaning issue sound like a huge inconvenience. It’s only added about two minutes to my overall morning routine. However, it’s something to think about if you’re a particularly busy or lazy person. If you already know that you tend to slack off with these kinds of things, the upkeep required by the SleepTight might be too much for you.

Frequently Asked Questions 

With so many different reviews for the SleepTight out there, it can be hard to track down specific details and specs, so I’ve put together a little FAQ to address any questions that my readers might have. I hope it helps!

Is the SleepTight safe to use?

Yes. Its materials are latex-free and BPA-free, and nothing needs to be strapped to your head or forced into your mouth. If the SleepTight ever feels uncomfortable, just pop it out.

Can I sleep in any position while wearing the SleepTight? Can I breathe through my mouth?

The answer to both of these questions is “yes.” Thanks to the SleepTight’s extra-large airway opening, you can rest comfortably in any position and with any type of breathing. Personally, I always sleep on my back and breathe through my mouth, but I’ve seen other reviewers talk about having different sleep habits, and it never seems to be an issue for them.

Can I use this product even if I have a nasal obstruction?

Yes. This is actually the reason that I purchased the SleepTight; I needed something that would work on my snoring despite my deviated septum and all of its associated problems. I didn’t have any difficulties with it, and you shouldn’t either.

How long will it last?

Assuming that you take proper care of it, the SleepTight should last anywhere between 6 – 24 months. A lot will depend on how hard and how frequently that you’re using it. Teeth grinding can shorten its lifespan; special cleaning solutions can extend it.

Can I wear dentures with the SleepTight?

The fit might be a little awkward since you have to bite down on the mouthpiece to get the customized fit, but if you’re willing to deal with a bit of a wiggle, the SleepTight can be successfully used with dentures.

Can I try it before I buy it?

Yes. The manufacturers offer a special 30-day trial where you only pay a small shipping fee to have the product delivered. If you like it, you can keep it and pay the full price after a month. If you don’t like it, you can send it back guilt-free without any more charges.

Final Verdict

It has a wide range of motion. It can be customized to create an exact impression of your teeth. It works with all sleep positions, and it allows for a lot of flexibility in terms of drinking, breathing and swallowing.

It isn’t a flawless product. Maintenance will be an issue, especially for people on the go.

All things considered, however, the SleepTight is such a great product that I have no problem recommending it to others. It’s attractive both inside and out. Try it for free and see if you like it, too!
