SleepTight Mouthpiece STZ Double Pack

Save almost $60 with the STZ double pack purchase

The STZ combines the proven snoring solutions of mandibular jaw advancement and gentle passive tongue retention to help keep your airway open during sleep.
The STZ is not like our competitor’s products, because the STZ does not squeeze your tongue into a bulb or strap your tongue down with rubber bands. The STZ allows you to have the important natural sleep swallowing.
Most users say that they can speak and drink water with the device in place.
Designed for use by both men and women.
To custom fit the STZ you will use the easy (“boil and bite”) process performed by millions of athletes who fit their own sports mouth guards.

The custom STZ fitting uses safe thermo-plastic materials to give you the most accurate fit, comfort, and performance. You can mold the STZ to your specific anatomy and customize it to solve your snoring problem.
The STZ custom fitting is unlike the “one-size-fits-all out of the box” approach offered by other mouthpieces.
You can confidently use the STZ because it is made in the USA, has been FDA cleared for snoring, and does not contain BPA or latex.

AFFORDABLE AND DENTIST DESIGNED: The STZ was created by a US dentist for his own snoring problem and now designed as an affordable snoring solution for almost anyone.

GUARANTEE: If you are not satisfied for any reason during your 30-trial period, you can return the STZ for a refund.

1. Bring to a boil, about 10 oz. (300ml) of water, then pour the hot water into another bowl. Wait about 10 seconds.
2. Then place the STZ into the bowl to soak and soften for 2 1/2 minutes. Use a spoon to hold the STZ under water. Don’t let the
spoon stick to the STZ.
3. After soaking, remove the STZ from the water. Check to make sure it is not too hot and straighten up any folded edges. Hold the
STZ with the “V” shaped notch up.
4. Place the STZ on the lower teeth first, in the center of your mouth. Work in front of a mirror. Then bite into the upper part of the STZ.
You might need to move your jaw slightly forward to align the upper.
5. While continuing to bite, use your fingers to firmly mold and compress all areas of the soft mouthpiece against the teeth and gums.
Suck in and push the tongue against the sides of the soft material especially front upper.
6. When at body temperature (about 6 min.) remove and place the STZ in an ice water bath to shrink fit for 5 minutes. To remove the
fitting handle, squeeze the wings on the front sides and slide off the front retainer clip; then push out the main part from the
back inside. Keep the fitting handle and use the same steps if additional fitting is desired.

Place the fitted STM into the mouth while sleeping and position your tongue into the opening. Clean with a very soft toothbrush and liquid anti-bacterial soap. Use our approved cleaning tablets weekly to keep the STZ fresh and clean. Store dry in the provided case. After a few days you can refit if the snoring has not improved. Need more help?
