What is the SleepTight Mouthpiece?

The SleepTight Mouthpiece is a Mandibular Advancement Device (MAD) meant to significantly reduce, or eliminate snoring. MADs stop you from snoring by holding your lower jaw slightly pushed forward in order to keep the back of your throat cleared. Otherwise, you lower jaw may move backwards and you tongue can fall to the back of your throat, partially blocking the airway, making the tissues in your throat and the back of your tongue vibrate, making you snore.

The SleepTight Mouthpiece takes the shape of your jaw through a simple boil-and-bite process. It has a hole to let the user breathe through his mouth, unlike many other mouthpieces that force you to get used to breathing through your nose. This means the SleepTight can be worn with a stuffy nose during allergy or flu season.

Like many other mouthpieces the SleepTight should reduce teeth grinding since it holds your teeth in place.

People with dentures or loose teeth should not wear it; and if you think you have teeth issues, you should ask your dentist whether you could wear any MAD (though asking your dentist anyways is a good idea).

The product has been cleared by the FDA, meaning it was deemed similar enough to other products already on the market that have been approved (by being extensively examined) by the FDA.

Finally, it has got some good customer feedback and many good reviews, though it still has not been on the market for long.

The Design and The Materials Used

The SleepTight mouthpiece is made of a BPA and latex free thermoplastic. There are no further details on the material used. It is a thermoplastic so it can be softened by putting it in hot water, and then molded to your jaw’s shape.

The mouthpiece is a Mandibular Advancement Device (MAD) that holds your jaw in a slightly forward position in order to clear the airway at the back of your throat, effectively stopping or significantly reducing snoring.

It has an airhole at the front allowing the user to breath through his mouth. This way, you will not be forced to breathe through your nose while wearing the device, which means you will be able to wear it even with a stuffy nose, unlike MADs with no air holes, or Tongue Retaining Devices (TSDs).

The device is also one-size fits all, which, oddly, means it should fit your jaw well after the boil-and-bite process, and you can’t choose the “wrong” size.

It is important for products you put in your mouth to be both latex and BPA free, which is the case for this product. The reason for this is that many people are allergic, or somewhat sensitive to latex, which means their gums can become excessively irritated if they wear a product with latex (a bit of irritation/sensitivity in the gums at first is normal though). As for BPA, many health-related institutions caution against its use because of potentially negative effects on the brain, heart, and it may also be related to changes in hormone levels that can lead to cancer.

How To Use The SleepTight Mouthpiece And How It Works

The SleepTight mouthpiece is a MAD that reduces snoring by keeping your jaw slightly pushed forward. Snoring happens when the airway in the back of the throat gets partially clogged, making breathing a bit more difficult and making the tissues in the back of the throat or at the back of the tongue vibrate. The clogging will happen when your jaw moves backwards, often when you are lying on your back, itself clogging the airway, which is made worse when the tongue also falls to the back of the throat. Therefore holding the jaw pushed forward should stop both the jaw and tongue from falling back enough to clog the airway in your throat.

Before using or shaping the SleepTight mouthpiece, make sure to brush your teeth well and clean your mouth. That way it will be easier to keep the device clean, and since the device will be resting on your teeth, it can trap the dirt around your teeth, which can be harmful to your teeth.

You will be shaping the device to your jaw yourself at home through a boil-and-bite process. You should carefully read the instructions that come with your device, but here is what they will look like:

  • Have a pot of boiling water, and one with cold water
  • Using a spoon place the mouthpiece in the pot of boiling water.
  • Leave it there for 3 minutes
  • Then take it out, and when it is cool enough, place it in your mouth using the white plastic piece, making sure the small indent is facing up
  • When placing it in your mouth, suck in your saliva to make it take the shape of your teeth as much as possible, and using your tongue and fingers, shape it further
  • After a minute or two, take it out and using a spoon place it in the pot of cold water
  • Check the fit, and if it does not suit you, you can redo the process at least three times before the material starts to degrade

Cleaning And Longevity Of The SleepTight Mouthpiece

The SleepTight is easy to clean and must be cleaned after each use. To clean it, simply use a toothbrush, toothpaste, and cold water. Make sure to get into all the little imprints left by your teeth. When you are done cleaning the device, rinse it in cold water and let it air dry.

It is also often recommended to clean your device once a week using a denture cleaner. To do this, let the device soak in the denture cleaner for around 10 minutes, or as per the instructions, then rinse in cold water, and let it air-dry. This way, your device will be guaranteed to be perfectly clean.

Make sure to store your device in a dry place, away from your dog.

The product should last you between 6 and 24 months of daily use depending on the user, and on whether it is properly cared for. Making sure to clean it after every use and once a week with a denture cleaner will help it last longer. Users who normally grind their teeth will usually shorten the lifespan of the product. 6 to 24 months is a really good lifespan for an over the counter mouthpiece.

Potential Side Effects

The side effects that come from wearing the SleepTight mouthpiece are not specific to it, but shared by all MADs, and they include

  • Jaw soreness
  • Excessive drooling
  • Dry mouth
  • And to a lesser extent: tender teeth, irritation of the gums, and minor changes to the way your jaw closes.

But all these side effects are likely to be at their worse in the first few days, and to disappear, or be significantly reduced, after the first week or so of daily use.

If your jaw is particularly sore, it may be because you did not fit it so well. Meaning after the first days if you experience bad jaw soreness, you can try remolding the device without pushing your jaw forward as much.

Clinical Trials

It seems like there has been a clinical trial run on this product but the full-length trial is not available online. Even if the product itself has not gone through a clinical trial, MADs in general have been proven to be effective remedies to snoring. The FDA has also cleared this product, meaning they deemed it similar enough to a product they had previously approved.

Will the SleepTight Anti-Snoring Mouthpiece Work for You ?

The SleepTight mouthpiece is a MAD whose reviews online have been really positive. The product has only been on the market for a few years, which should explain the relatively small number of reviews it has. It will stop you from snoring if you snore because of a partial clogging at the back of your throat (which is the most common cause of snoring). Since it has a hole at the front you won’t have to get used to breathing through your nose. It also is fitted to your jaw through a boil-and-bite process, a common, and effective way of molding mouthpieces.

The side effects, mainly jaw soreness, excessive drooling, and dry mouth, should go away relatively quickly, and according to reviews online, all these side effects are also comparatively mild for the SleepTight Mouthpiece when compared to other products because of its good fit and quality.

An interesting detail of this mouthpiece is that it can be tried for 30 days for only 9.95 USD. If you do not like the product you can return it within that timeframe, and if you do the rest of the payment (70 USD) will be processed automatically. This does not include the cost of shipping, which will be 9.95 USD for shipping inside the US, and more for international shipping.

Remember that this device cannot be worn by people who wear dentures, have loose teeth, or naturally really sensitive gums. Though before buying any MAD you should consult with your dentist.

How Much Does it Cost and Where to Buy

The SleepTight Mouthpiece can be bought on its official website:

It costs $79.95, plus $9.95 to ship it anywhere within the US.

For only $9.95 (plus $9.95 for shipping) you can use it for 30 days as a trial. If you are pleased with the product, the rest of the amount ($70.00) will be automatically deducted  from your credit card, and if you want to return it, you can send it back and nothing more will be charged to your card.

There is no money back guarantee period, which is rare for this kind of product, because of the 30 day trial period that only costs $9.95.

Company behind the SleepTight Snoring Mouthpiece

According to the website, the product was developed by an American dentist Dr. Mike Williams who is a member of the American Academy of Sleep Medicine and a British mouthguard researcher. They developed the product to help solve Dr. Mike Williams’ snoring problem. They worked collaboratively for many years and created the final product after evaluating the reviews of their product, made by many users.

The Company is BBB Accredited, which means it responds well to the comments, questions, and complaints of customers. The firm’s product, though relatively new to the market, has been given really good reviews online.

The SleepTight Mouthpiece is also FDA cleared; the FDA has deemed it similar enough to another product that they had previously approved.

Summary of the SleepTight Mouthpiece

The device is a MAD, fitted at home through a boil-and-bite process. It retains your jaw in a forward position, clearing the back of your throat, and the boil-and-bite process will make it much more comfortable for you to wear. It is made of a BPA and latex-free thermoplastic and has been cleared by the FDA, making it safe to use daily.

It has a breathing hole at the front, allowing the user to breathe through their nose. Though  because it rests on your teeth, the appliance cannot be worn by people with dentures or loose teeth.

It should be cleaned after every use with toothpaste, a toothbrush, and cold water, letting it air dry after the process. And it should also be cleaned once a week using a denture cleaner, letting it soak in the solution about 10 minutes, rinsing it in cold water, and again letting it air dry. If properly taken care of, it can last up to 24 months (6 months minimum).

The potential side effects of the product aren’t specific to it, but common to all the MAD family, and include jaw soreness, dry mouth, and excessive drooling. There are a few other less common side effects too. But all of these should be at their worse in the first few days, and quickly disappear.

Finally, the product was developed by specialists, their company has been BBB Accredited, and has received good feedback and reviews online.
