Choosing the Right Mouthpiece


The ZQuiet Comfort Refills are the same mouthpieces supplied in your original 2-Size Comfort System Starter Pack and is recommended for most people.  Replace it at least every 4 to 6 months for the best results.


Designed for people that clench and grind their teeth and/or prematurely wear out the standard Comfort Mouthpiece.  Made with a stiffer grade material and extra strong hinge, the ZQuiet Firm Refill should only be used by people with very healthy teeth and strong jaws.

Find Your Size  

Before you reorder, identify the ZQuiet® mouthpiece size that worked best for you.



How to Determine the Correct Size:

Identify the mouthpiece size by looking for the “1” or "2" inside the circle on the underside of the tray for the upper teeth as shown in the diagram below.
