What is a snoring mouthpiece?

Snoring mouthpieces, also referred to as "snore guards", "snoring mouth guards", "anti-snoring mouthpieces" and other similar names, are devices which advance your lower jaw to stop snoring. There are generally two kinds of snoring mouthpieces, ones that rest on your teeth, and ones that pull your tongue forward. SleepTight Mouthpiece rests on your teeth, advancing your lower jaw by pulling it forward, opening your airway.

Pros And Cons Of SleepTight Mouthpiece

How It Works

How does the SleepTight Mouthpiece work?

Snoring is mostly a result of vibration in your airway. The vibration occurs during sleep because the muscles relax.

The SleepTight Mouthpiece works by keeping your airway open during sleep.

First, you make an impression of your teeth while your lower jaw is extended. Once the impression is set, you wear the mouthpiece during sleep.

The SleepTight Mouthpiece keeps your mouth in a position that keeps air flowing without obstruction thus eliminating snoring.

Will the mouthpiece cause gagging?

Rarely, you should wear SleepTight for a few minutes at a time if you experience gagging so that your body adjusts.

Fitting Process

Step-By-Step Fitting Instructions for SleepTight Mouthpiece

Note: you should brush your teeth before fitting SleepTight Mouthpiece.


  • Stove (do not use microwave)
  • Water (2 cups)
  • Teapot or saucepan to boil water
  • 2 glass or ceramic cups (1 for the hot water to be poured into and 1 to cool the mouthpiece)
  • The SleepTight Mouthpiece and its fitting plug
  • A timer
  • Spoon or tongs (to keep the mouthpiece underwater and remove it from the water)


  1. Boil water and pour into a cup. Let the water sit for 1 minute. If the water is too hot then the SleepTight may become rough. Do not boil water in a microwave!
  2. Fully insert the fitting handle. Keep the mouthpiece under water for 3 minutes using a spoon or tongs. This makes the mouthpiece soft enough for an impressiion of your teeth.
  3. Remove the SleepTight from the hot water and shake off excess water. Make sure it is not too hot to put in your mouth.
  4. If the edges of the SleepTight have folded over, straighten them back up into the original horseshoe shape.
  5. Make sure the SleepTight is right-side up. There should be a "V" shape notch on the top. Re-check the fitting handle to make sure it's secure before fitting.
    • Maintaining the fitting handle in its correct position, fully inserted, is critical to keeping the airway opening and preventing it from collapsing during fitting.
  6. Place the SleepTight onto the lower teeth first, work in front of a mirror to center the device.
  7. Bite down hard into the mouthpiece and move your lower jaw far forward to align the edge of the lower teeth with the edge of the upper teeth, or slightly forward. You will see the fitting handle rise up. The fitting handle will prevent the back teeth from touching and will maintain the front breathing opening.
    • Advancing the lower jaw, ideally with your hands, is critical to successfully fitting the mouthpiece.
  8. While holding the jaw forward, firmly press the mouthpiece against all of your teeth using your fingers and tongue while the material is soft for 30 seconds. Suck in and push the tongue against the sides of the soft material.
  9. Take the SleepTight out and place it into cool water for 1 minute. You can use ice cold water to make a shrink fit, only do this if you are satisfied with the impression.

NOTE: If the mouthpiece is not fit correctly, without a firm impression, you will need to go through the steps again. You can re-fit the mouthpiece a couple of times if you didn't bite down hard enough to make a good impression. After this, the material will become too soft to fit tighly.

The SleepTight Mouthpiece can stop your snoring. The most important part of making this happen is fitting it correctly.

To fit SleepTight correctly, you need to make sure to hold your lower jaw forward with your hands while biting down hard, press the material around your teeth to make a tight impression. The material needs to be pressed firmly against your teeth by using your fingers.

It is possible to re-fit the mouthpiece but it cannot be adjusted incrementally.

The mouthpiece is FDA cleared, not only for snoring, but also for mild sleep apnea.
