  • It is small, flexible and low profile.
  • It will increase your energy with proper sleep.

Time to take a look what this device can do and if it may work.

Who Makes ZQuiet?

This device was designed by Dan and Katerina Webster in conjunction with Avery Lieberman, DDS.

The Websters sought a solution to deal with Dan’s snoring. They formed the company Sleeping Well LLC.

Dr. Lieberman has over 20 years dental experience. This experience includes the treatment of snoring and sleep apnea with oral appliances. He is also the founder of The Treatment Center for Disturbed Sleep.

The company also supplies custom oral appliances to dentists and medical professionals. They are aiming to build a list of trained sleep dentists.

What Is ZQuiet?

The medical term for your jawbone is a mandible. Advancement means “the act of moving forward”. This means that an MAD – like a ZQuiet – is a mouthpiece that moves the jaw forward.

So how does moving your jaw forward help relieve snoring? Let see what causes snoring and how this device works.

How Does ZQuiet Work

how it works

There are many reasons why people snore. One of these reasons is the partial obstruction of the airway to and from the lungs. This may be caused by relaxation of the muscles in the tongue and throat tissue.

When we sleep the lower jaw relaxes. This in turn causes the surrounding muscles and tissue to relax. Gravity causes your tongue to fall backwards towards your throat. This narrows the airway, restricting air flow. As a result the air passing through vibrates and causes a noise. This is what we call snoring.

An MAD aims to help lessen the restriction on your airways. It does this by moving the jaw forward and away from the back of your throat. This may also cause the tongue to move forward and open up the airway. This can reduce the air resistance that leads to snoring.

This device offers a Two Step Custom System and Natural Hinged Technology.

Two Step Custom System

  • You are supplied with two mouthpieces. They are different sizes depending on whether you need a small adjustment to your jaw, or a little more. Having the two options allows you to see which may work better for you.

Natural Hinged Technology

  • The device has soft hinges between the lower and upper jaw mouthpieces. This aims to to provide maximum flexibility and comfort. It claims to adapt with the way you sleep and provide maximum relaxation.

The device is made from thermoplastic elastomer. It is soft and flexible. The material is non-toxic, odorless, and tasteless. It does not contain latex or BPA. The material used has passed strict consumer safety testing. It is made in the USA. It has been cleared by the United States Food and Drug Administration as safe for use.

The product is designated a Class II medical device by the FDA. This means the company had to prove that the product is effective. It must achieve its intended purpose.

It is ready to use straight from the box. You do not need to mold it. There is no special fitting procedure. If needed, you can trim it with small scissors to improve fit. After trimming the company advises that you use a nail file or emery board to smooth any rough edges. This will avoid irritation to the gums.

The device in may be cleaned with warm water and mild dish soap. The company advises that you use a toothbrush for best results. They do however caution not to use toothpaste as this may discolour the device. It may also alter the surface of the material. Rinse it thoroughly to remove all soap prior to storage.

Ron F reports:

I’ve been using ZQuiet® for 3-4 years now. I had been thinking I needed to try something for my snoring for awhile, then I put action to it when I was sent to the basement when I was keeping everyone IN THE HOUSE up on vacation with my in-laws! I ordered it right away and it was waiting for me when we got home from vacation. It worked from night 1. I used to think I was wearing this for my wife, so she can sleep. It hit me a couple of weeks ago when my wife was out of town for a night, so I didn’t wear it. I ended up waking up several times and just had a restless night of sleep. Not only is ZQuiet® for my wife, but it’s FOR ME TOO! Thanks for thinking of this great product! I’m very rested!

Not everyone is quite as happy. Some people report that the product may not last very long.

Adriana Priscal writes:

It works alright. I bought the zquiet for my husband not too long ago. It definitely has reduced his snoring and allowed me to get some rest, but I’m not overwhelmed with the results. My biggest complaint is the quality of the product. I am already starting to see signs of aging from use and i’m not really sure how much longer it is going to be before I have to replace it. Would I recommend? Yes

Meanwhile some people find it too uncomfortable to use. There are also comments about poor customer service.
