ZQuiet Advance comes pre-assembled and takes less than 5 minutes to mold to your teeth. The mouthpiece molding process is easy and it comes with detailed instructions and an instructional video.

It depends on the individual, but many customers find that their mouthpiece lasts for many months of nightly use. Just like a toothbrush, we recommend replacing ZQuiet Advance at least every 6 months, or if it is excessively worn or shows any signs of damage.

It will work the first night for people who only need a small amount of jaw advancement. If you continue to snore, spend a few nights adjusting to the sensation of wearing it and then change the strap sizes to find the optimal jaw advancement needed to completely stop snoring.

The mouthpiece is made of 3 different types of FDA approved, medical-grade plastics which are specially formulated for medical devices and have passed stringent biocompatibility testing to ensure safety for intraoral use.

Both the Comfort and Advance mouthpieces share many similar traits. They are both FDA Cleared, safe, and effective, made with medical grade materials, are thin and low-profile, and have a hinged design that allows natural jaw movement. The differences are that the Advance is moldable and has 4 levels of jaw advancement adjustment and works with straight or crooked teeth, whereas the Comfort mouthpiece is ready-to-use out of the box and comes in 2 jaw advancement sizes and works best with straight front teeth or over Invisalign or other clear aligner treatments.

If you didn’t get a deep impression or the fit doesn’t feel correct after molding the device the first time, each mouthpiece tray can be re-boiled and molded a couple of times if necessary.
