Should I start with Size #1 or Size #2?

Size #1 gives a slight 2mm jaw advance and suits overbites or normal bites with light to moderate snoring. If you are new to ZQuiet, the two-size starter pack lets you test both before committing to one.

How often do I replace it?

ZQuiet recommends a new mouthpiece every 4 to 6 months for hygiene and performance.

Can I breathe and talk with it in?

Yes. The open front and living hinge let you open your mouth, talk and take a sip of water.

Does it treat sleep apnea?

No. It is FDA-cleared for snoring, not for obstructive sleep apnea. Loud snoring with gasping or daytime sleepiness warrants a medical evaluation.

Will it hurt my teeth or jaw?

Mild jaw or tooth soreness and drooling can happen at first and usually fade with consistent use. Stop and see a dentist if pain persists.

Can I wear it with Invisalign?

Some owners wear it alongside their Invisalign trays and report it works; check with your orthodontist first.

About the ZQuiet Adjustable Mouthpiece

The ZQuiet Adjustable Mouthpiece is an anti-snoring mouthpiece. This refill pack contains one blue Comfort Size #1 mouthpiece, which provides a slight +2mm jaw adjustment. It is FDA cleared as a snoring solution.

It is made from a soft thermoplastic compound that does not contain silicone, latex, or BPA. The low-profile, open-channel design has a patented living hinge, so the mouthpiece conforms to the mouth and is less bulky than products with a hard plastic shell. The open front lets you open and close your mouth naturally, talk, or take a sip of water.

The mouthpiece is ready to use, with no boiling, molding, or impressions required. Minor side effects such as drooling or jaw discomfort can occur and tend to fade with consistent use. For hygiene and performance, replace it every 4-6 months.
