Several anti-snoring mouthpieces side by side

How we compared them

We looked at five things: how much the jaw adjusts, how you fit it, whether it supports the tongue, FDA clearance, and the guarantee.

We make VitalSleep. We did not run lab tests, hire testers, or pay for an outside study. Facts and prices for the other brands come from each brand's own website, checked on September 30, 2026. Our picks are our opinion as a seller.

When another mouthpiece is the better choice

We would rather you buy the right one than buy ours and send it back.

You don't want to mold anythingZQuiet works out of the box.
Your tongue falls back when you sleepSnorple or Zyppah add tongue support. VitalSleep does not.
You want the lowest priceZQuiet and Snorple are $59.95. VitalSleep is $149.95.
You want the longest trialSnorple gives you 100 nights.
You have, or might have, sleep apneaSee a doctor first. ApneaRx is built for mild to moderate sleep apnea.

Why we still think VitalSleep is the best pick for most jaw snorers

You can fine-tune it. Most snorers need a few tries to find the right setting. 1mm steps up to 8mm give you room to do that.
It is FDA-cleared. Not every mouthpiece on this list is.
It is backed after the trial. Our one-year unlimited warranty and free replacement cover you long after night 60.

A note on sleep apnea: Loud snoring can be a sign of sleep apnea. VitalSleep is cleared to reduce snoring. It does not treat sleep apnea. If you stop breathing, gasp at night, or feel very tired during the day, talk to your doctor.

The bottom line

If your snoring comes from your jaw, VitalSleep is the one we'd try first. Yes, we're biased. That's why you get 60 nights to decide.

Adjusts in 1mm steps. FDA-cleared. One-year unlimited warranty and free replacement.
