What Is A Snoring Mouthpiece?

A snoring mouthpiece is a device which you can use use to stop snoring at night. A snoring mouthpiece is also referred to as a "snore guard", "snoring mouth guard", "anti-snoring mouthpiece" and other similar names. There are two main types of snoring mouthpieces, mandibular advancement devices and tongue stabilization devices. PureSleep is a mandibular advancement device. This means it advances the lower jaw using the teeth, not the tongue.

How Does PureSleep Work?

PureSleep is a self-molded retainer which reduces snoring by holding your lower jaw slightly forward of its normal position while you sleep. By keeping the jaw slightly forward, it reduces the risk of the tongue collapsing over the throat, which causes a partial obstruction of the airway. That obstruction causes snoring.

When the airway is kept open, the tissues near it do not vibrate. Snoring is caused by vibration in the airway so keeping the jaw forward, and hence the airway open, prevents snoring.

PureSleep is made of an upper and a lower piece that you can join together in one of three settings, depending on your bite. After the pieces are connected to your individual setting, the device is boiled to soften the material so that you can mold it your teeth. This take less than a minute. Once the device has been molded, you cannot further adjust it.

While PureSleep can be customized to your bite, it cannot be changed once its initial impression. You will want to have the setting in a position where your lower jaw is as far forward as possible without discomfort. This will open your airway up as much as possible during sleep, preventing snoring to the fullest degree.

What Makes PureSleep Unique?

puresleep parts

PureSleep is different than many other snoring mouthpieces because it has two parts which can be joined together to fit the individual's bite.

Once the upper and lower parts are fit together, they must stay in place because the fitting process solidifies the setting through heat. This makes it different than a mouthpiece like SnoreRx which can be adjusted multiple times.

If you are able to make a firm impression and the jaw setting you use works for you, PureSlepe may be effective.

How Do You Fit PureSleep?

Preliminary steps:

  1. Brush your teeth, if you have partial dentures, remove them.
  2. Determine what type of bite you have.
    • If your upper front teeth slightly overlap your lower front teeth, that is a typical bite. Use the Typical Bite setting (the two holes closest to the front of the device).
    • If your upper fron teeth meet evenly with or slightly behind your lower front eeth, use the Mild Underbite setting (user the center two holes).
    • If your upper front teeth are much farther behind your lower front teeth, use the Severe Underbite setting (user the two holes closest to the back).
    • If your upper front teeth are much farther forward of your lower front teeth, use the Overbite setting (use the two center holes and flip the device over so the top component is now on the bottom).
  3. Attach the upper and lower parts of the PureSleep device in the setting that is best for you. The upper and lower components of PureSleep are designed to fit together. The top component has two plastic "teeth" that extend from the front of the unit. You will also see plastic pins, which fit into holes in the bottom component in three possible positions.
  4. Fit the device.


  • A medium size pot for heating 1-2 quarts of water
  • A spatula, perferably slotted
  • A timer that counts in seconds
  • A toothbrush and toothpaste
  • Cuticle scissors
  • A towel

Step-by-step fitting instructions:

  1. Boil 1-2 quarts of water in a medium sized pot to a low boil.
  2. Using a spatula, slowly lower PureSleep into the pot of hot water. Do not move the device around because the two components could separate. Keep PureSleep in the heated water at a low boil for 2 minutes.
    • If the two components separate in the water, let the device cool for one minute and then repeat the process.
  3. Remove your PureSleep device and wait 15 seconds for it to cool.
  4. Insert the device into your mouth.
    1. Thrust your lower jaw foward as much as you comfortably can.
    2. Place PureSleep into your mouth.
    3. While holding your jaw forward, bite down very firmly into the softened plastic.
    4. Continue holding the device in you rmouth for 30 seconds. Note: It is normal for your teeth and gums to feel very warm during the fitting process. If it is too uncomfortable, remove and replace PureSleep.
  5. Trim away excess material for greater comfort. There may be some soft plastic at the back of the device which has been fused or melted together. This is normal and holds the two pieces together. Excess soft plastic may have been displaced or created during fitting and this could bother your tongue. Hold PureSleep with a towl and carefully cut away any excess material using cuticle scissors.
  6. Confirm the impression. If you did not make a firm impression, you can try re-fitting the device in the hot water again. You can only re-fit the device three times, after this the material may become too weak to be effective.

Common mistakes in fitting:

  • If you do not wait 15 seconds after removing PureSleep from hot water, you could burn your mouth.
  • If you wait longer than 15 seconds to bite into the device after removing it from hot water, you won't get a deep impression.
  • Most people naturally move their lower jaw backwards when they bite down. Hold your lower jaw foward with your hands while biting down.
  • Don't be afraid to bite down firmly. A deep impression will give better comfort and effectiveness.

How Long Does It Take To Get Used To PureSleep?

At first, some people may have trouble sleeping with PureSleep. It may cause some excess salivation or a slight "gagging" response. If this happens, make sure you have trimmed away all excess soft plastic. You can get used to wearing it by wearing it before bed.

If the device bothers you while sleeping, you should take it out and go back to sleep. In just a few nights you should sleep be able to sleep with it longer until you can wear it an entire night.

You may have some jaw, teeth or gum soreness as you get used to wearing the device. If you stop wearing it before your jaw adjusts to it, you may need to re-adjust and go through this phase again.

If you want to shorten the time it takes to get used to wearing PureSleep, you can perform "jaw stretching" exercises in the morning. To exercise your jaw, gently push your jaw backwards while relaxing the muscles in your jaw. Hold this position for about one minute.

You should not experience severe, sharp pain when using the device. If this happens, you may have TMJ issues and should stop using the device immediately.

What Is The Return Policy?

You have 30 days from when you order the device to redeem the PureSleep money-back-guarantee. This is more than enough time to get used to the device and know if it will work for you.

PureSleep is made in the United States.

Is PureSleep Patented?

Yes. PureSleep has a patent in the United States, No. 5,499,633.

Summary Of PureSleep

PureSleep is a snoring mouthpiece which works by advancing your jaw, just like other mandibular advancement devices. What makes PureSleep different is that is has two pieces which require you to first set your jaw position. After that, you cannot re-adjust the setting because fitting process using boiling water locks it in place. PureSleep may work to stop your snoring but getting the initial fit done correctly is very important.

If you are looking for a mouthpiece simialr to PureSleep which can be adjusted multiple times in smaller increments, consider SnoreRx.
