Anybody who has experienced nighttime snoring knows the unseen struggles that come along with the condition.  People might joke about being difficult to sleep next to, but snoring and mild obstructive sleep apnea (which often go hand in hand) can have severe effects on your ability to get enough good quality sleep, not to mention affecting anyone who might be trying to sleep next to you.

However, there are anti-snoring mouthpieces that really work, and can relieve even chronic snoring.  There are more than 30 different high-quality options on the market, but a few stand out above the rest.

ZenGuard by ZenSleep is a recent addition to the pool of choices, which offers a low cost, high-quality option for snoring solutions.  I tested it out and compared the results to other popular mouthguard options.

The ZenSleep Options

ZenSleep is the company behind ZenGuard.  They are a relatively new company and lack the credentials of many larger companies.  Based out of Scottsdale, Arizona, they cater for an American market.

ZenSleep doesn’t go out of their way to promote a high-level orthodontist or sleep specialist as their founder or rely on big names to sell their product.  It’s tricky to find out information about their credentials and the identity of the people involved in designing and making the product.  According to their Facebook page, the company was founded in December of 2014, so it’s still a relatively new option for anti-snoring appliances.

As well as the ZenGuard, ZenSleep also sells other sleep aids such as the ZenVents, which are nose vents that aerate your nasal passages, the ZenStrap which is a chinstrap that keeps your jaw closed, a face mask called the ZenMask and earplugs called ZenPlugs.  They also sell a kit that contains one of each product.

The relative anonymity of ZenSleep has two major benefits – ZenSleep sells their mouthguards at a comparatively low price, and you do not require a prescription to purchase one – unlike most similar models.  Their products are still made from high-quality materials and have high-performance ratings from users as well as a money back guarantee, which makes them a great option for a TSD.

Why the ZenGuard?

While the ZenGuard might be a new product on the market, similar TSD devices have been available for over a decade.

There has been a lot of research into their effectiveness at preventing snoring and mild sleep apnea, and they have been proven to be just as good at their job as MAD devices.

Obstructive Sleep Apnea and snoring are closely related – most people who have one suffer from the other.

The ZenGuard is worth trying because it is a relatively affordable option, it has a money back guarantee, it does the same job as some similar items that cost a lot more, and really does work for most people – it worked for me!

How the ZenGuard Works.

The ZenGuard prevents snoring by attaching to the tip of the tongue and holding it forward, which makes it a TSD.  It is shaped like a bulb and is squeezed and placed on the end of the tongue.  It has wing-like extensions on the upper and lower sides, which stays between the lips and gums.  The protrusions combined with the suction grip on the tongue keeps the muscles pulled away from the airways.  It does make you look a little like you’re using a pacifier, but I guarantee your spouse will stop laughing after their first quiet night free from snoring.

The ZenGuard is made from a medical grade silicone, which is free of controversial synthetic plastic compounds called BPA.  It is especially important to know the material that your mouthpiece is made of because the device will be put into your mouth each night, and remain there while you sleep.  Silicone is a non-reactive material that is soft and comfortable to wear, and won’t cause health problems.  The ZenGuard also has a specialized V-shaped notch to fit comfortably over the frenulum, the piece of skin that attaches the bottom of the tongue to the floor of the mouth – commonly known as a “tongue tie”.

Comparison With Other Popular TSDs

ZenGuard vs aveoTSD = ZenGuard Wins

The ZenGuard closely resembles a TSD called aveoTSD.  One of the first TSDs available on the market, the aveoTSD has been around for over a decade.

The aveoTSD was developed by a sleep specialist and orthodontist and is FDA approved.  However, you will need a prescription to access this device, and it costs more than the ZenGuard.

I would personally prefer to pay less for the same results, so my preference is the ZenGuard in this case.

ZenGuard vs Good Morning Snore Solution (GMSS) = GMSS Wins

One of the most popular models that the ZenGuard is often compared to is the Good Morning Snore Solution.  This device functions similarly to the ZenGuard, and is fairly comparable in pricing and the materials used.

While both are TSDs and work by creating a suction to hold the tongue in place, the GMSS is slightly better in a number of ways.  It is FDA cleared, and the company is accredited with the Better Business Bureau.

The GMSS was designed by a dentist and is suitable to use with dentures, which is handy for a large portion of snorers.  It’s smaller than the ZenGuard, and doesn’t take up as much room in your mouth.

I would still say that the ZenGuard is an excellent option, but I personally like the GMSS is slightly more.

Cost can vary widely between each type of mouthpiece, and can be a major deciding factor when people choose an anti-snoring device.

The ZenGuard has a very achievable price, as it retails for around $97 USD and includes free shipping.

However, this anti-snoring mouthpiece seems to only be available within the United States.

ZenGuard does come with a 90-days money-back guarantee, stating:

“If you are not completely satisfied, simply return your purchase within 90-days for a full refund.  We believe in our devices and offer 100% guaranteed results.”

That means that you can trial the product at a low price with free shipping, and return it if you’re not satisfied with the results.  That makes the ZenGuard a very low-risk purchase that could significantly improve the quality of your sleep.

The website does give you the option to pay for faster shipping, and you can also purchase an extra $10 warranty for the ZenGuard.  I didn’t bother, but you might prefer the added security.

Technically speaking, anti-snoring devices should be FDA cleared as they are classified as class II medical devices by the FDA.  A brief look at the FDA site doesn’t show any listings, but there could be a number of reasons for that – listing under a different name, for example.

This anti-snoring device is so similar to other, commonly used designs that there is little doubt that it would not be as effective as the other models.

Possible Issues

The product does not come with instructions, which is a good reason to practice.  It should be fairly self-explanatory, especially if you have experience using TSDs, but you can find plenty of videos online to show you if you do need help.

You might get some tongue soreness when you start using the ZenGuard appliance.  This could cause you to lose sleep and is uncomfortable, which is another reason to practice before attempting to use it at night.  It does take some dedication to use a device like this, so give it time before you decide it doesn’t work.  The money back guarantee lasts for 90 days so it’s worth giving yourself at least a few weeks to see if the product works for you.

ZenGuard mouthpieces are ordered online, and the website can be aggressive with their sales tactics.  If you enter the site knowing what you want, don’t be tempted by the other offers, and you might be rewarded with a discount on future purchases once you have bought your appliance.  However, if you are open to trying different options, ZenSleep has some high-quality, low-cost products.

Some people who use TSDs for the first time experience an increase in the amount of saliva their mouths produce; in other words, excessive drooling.  It might be an unpleasant side effect, but it should be temporary.  Your mouth is getting used to the device and it takes your brain a while to adjust to the correct saliva levels.  After a few weeks, most users report these symptoms going away.

Some users have said that the device can slip off in the night.  The best way to avoid this situation is to practice varying the amount of suction that you use to hold your tongue in place.  Too much will cause discomfort, but too little means it will slip off at night.  Remember that it might take you a few goes to get it right, and will definitely take you some time before it becomes completely comfortable.  If you stick with it, you will see results.

My Personal Experience

I have tried so many different models that it takes a high-quality product to impress.  The ZenGuard looked exactly as expected, and came on time with the promised free shipping.  It looked and felt high quality, made from soft materials that were flexible and fit well.

I tested the ZenGuard for 3 weeks.  After rinsing the mouthpiece in hot water, I pushed my tongue gently into the ZenGuard until it touched the sides, and then squeezed the bulb which creates the suction.  The amount of squeezing varies the suction you will experience.  Sometimes I needed to use a gentle pumping action to draw my tongue properly into the device.  When I was ready to remove the device, I pressed on the sides to break suction and easily removed the mouthpiece.

It was absolutely effective in stopping my snoring, and my wife noticed that the quality of my sleep had improved when she woke and didn’t hear the usual snoring.  I found it very comfortable and easy to use, although new users of a TSD might have a slightly sore tongue in the morning or have some saliva on their pillow in the morning.  I didn’t experience these negative side effects, but it could be because I am used to trialling these anti-snoring devices.  With prolonged use, you will become more comfortable – and it is worth it for the benefits!

I was somewhat surprised that a cheaper model TSD that has no explicit approval from the FDA would work so well, but it really did the job.  With free shipping and the money back guarantee, it’s really low risk for you to try, especially if you are wondering if a TSD might be right for you or you don’t want to get a prescription.

Tips for Using

Don’t expect to use the device on the first day you receive it – the best idea (and one suggested by the manufacturer) is to accustom yourself to the right amount of suction, and the proper placement of the anti-snoring appliance.  Too much suction will cause discomfort, and too little suction will mean the mouthpiece will slip over your tongue.  I practiced for a few days while watching television before bed, so I could get used to the placement that was right for me.

Rinse the ZenGuard in hot water before using it, with the V notch facing downwards, to help soften the silicone which makes it easier to fit onto the tongue.  After each use, it’s a good idea to wash the TSD with hot water and maybe a very mild detergent – mouthwash or chemical products will damage the silicone, void the warranty and shorten the lifespan of the mouthpiece.

Sometimes it can be hard to subjectively decide if a device is working.  Unless you get your wife to monitor your snoring you really need another way to measure the effect that the ZenGuard is having on your night time snoring.  There are many great apps available for smart phones that can measure your snoring, and many modern fitness trackers can provide data about the quality of your sleep which is useful for comparison.

Here are a Few Reviews from Actual Customers

“My husband snores like a bear, so bad that I leave and go in another room because ear plugs don’t work, I am now 4.5 months pregnant and sleeping in another room and ear plugs will soon not be an option! THIS WORKS! It’s like he’s not in bed with me, lol.” – Nicole

“It is way better than the CPAP mask and it works well for me. This is my first ZenSleep product and they work if your problem is snoring due to your tongue blocking the airway when you sleep. The product does work and it takes time getting used to it. It is way better than the CPAP mask I was using and waking up at night. Get one and sleep tight.” – Dan

Final Summary

I can’t say that the ZenGuard is the very best anti-snoring product on the market, but it is definitely one of the best options for the price, function and ease of access to the product.

The device is made from high-quality materials, is easy to use and easy to clean, is very durable and does a good job to reduce or eliminate snoring.  The results are comparable to other models that cost a lot more than the ZenGuard.

There might be some discomfort initially and there is a definite learning curve while practicing how to achieve the best fit.

The company is not quite as well-known as other manufacturers making similar products, and there is no obvious FDA approval on this device which might put some people off.  However, on the other hand, no prescription is needed so you can trial it straight away without having to make a separate doctor’s appointment or consulting with a sleep specialist.

The best thing about the ZenGuard is the value for money.

For a device that generally costs a great deal more, you can expect the same or similar results as the more expensive models of anti-snoring device.

With the money-back guarantee and free shipping, it’s worth giving this product a try and seeing if you can reduce your snoring with this simple device.
