How Does The SleepTight Mouthpiece Work?

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.

Step-By-Step Fitting Instructions for SleepTight Mouthpiece

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.
  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 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.
  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.
