Side by side

Two types, and why it matters

Jaw-advancing devices (MADs) clip over your upper and lower teeth and hold your lower jaw slightly forward. That pulls the tongue away from the back of the throat. VitalSleep, SnoreRx and ZQuiet all work this way.

Tongue-holding devices (TSDs) sit in front of your lips and hold the tip of your tongue forward with gentle suction. They don’t touch your teeth, so jaw problems and dental work matter less. Good Morning Snore Solution is the best-known one. Because your mouth is sealed around it, you need to breathe easily through your nose.

For most people, start with a jaw-advancing device. It has the stronger research behind it, as the evidence section explains.

VitalSleep: best overall

VitalSleep molds to your teeth in hot water, then uses a small key to move the lower tray forward from 0 to 8 mm, 1 mm at a time. You start at zero and work up only as far as you need (VitalSleep).

• Why we’d pick it: the widest adjustment of the four, a women’s size about 10% smaller, free size exchanges, and 60 nights to decide. The brand also offers a year of free replacements.
• Trade-offs: it costs twice what SnoreRx does. It has no hinge, so your mouth stays mostly closed while it’s in. It needs natural teeth to grip and isn’t recommended with full dentures.
• Cost per night: about 33 cents a night if it lasts a year, the lifespan the brand gives for regular use.

SnoreRx: best value

SnoreRx is also boil-and-bite and adjusts in 1 mm steps, with a built-in scale so you can see your setting. The brand says most people need only 1 to 3 mm of advancement (SnoreRx).

• Why we’d pick it: fine adjustment for $59.99, half VitalSleep’s price. The $99.99 SnoreRx Plus adds a hinge so your jaw can move up and down, and comes apart for cleaning.
• Trade-offs: one size only, and a 30-night guarantee, so you have less time to find your setting. The brand asks for up to five nights to get used to it.

Good Morning Snore Solution: for people who can’t wear a jaw device

GMSS is a soft tongue-holding device. There is nothing to mold: it holds the tip of your tongue forward with gentle suction, right out of the box. The brand calls it the only FDA-cleared over-the-counter tongue device (GMSS).

• Why we’d pick it: it doesn’t rest on your teeth, so it’s an option if jaw soreness, crowns or braces rule out a MAD. The brand lists it as safe with braces.
• Trade-offs: you must breathe comfortably through your nose. The tongue suction can take some getting used to, and the research favors jaw devices.

ZQuiet: the easiest start

ZQuiet is a hinged jaw-advancing device. There is no boiling or molding. The starter pack includes two sizes, so you can step up if the first one isn’t enough (ZQuiet).

• Why we’d pick it: the hinge lets your mouth open and close, it’s ready the night it arrives, and you get 60 days to try it.
• Trade-offs: no fine adjustment. If neither size feels right, you can’t tune it the way you can a VitalSleep or SnoreRx.

What the research says

The main guideline comes from the American Academy of Sleep Medicine and the American Academy of Dental Sleep Medicine. It recommends oral appliances, rather than no treatment, for adults who want treatment for snoring without sleep apnea (Ramar et al., 2015).

There’s a catch. For sleep apnea, the same guideline suggests a custom, adjustable device fitted by a qualified dentist over store-bought ones. It also says diagnosing snoring is a job for a sleep physician (Ramar et al., 2015). So a boil-and-bite device is a reasonable first try for plain snoring, not a stand-in for dental care.

On tongue devices, a 2017 meta-analysis of 16 studies and 242 patients found they cut the apnea index by 53% on average (Chang et al., 2017). A 2024 meta-analysis of 42 studies compared the two types in mild sleep apnea. Jaw-advancing devices reduced the index by 58%, against 21% for tongue devices (Liao et al., 2024).

Those studies measured sleep apnea, not snoring alone, and mostly used clinician-fitted devices. Treat them as a guide to which type works better, not a promise for any one product.

Safety cautions

• Expect a settling-in period. Extra saliva, tooth pressure and a sore jaw in the morning are common at first. VitalSleep lists bite changes, tooth and gum soreness, jaw pain and drooling among possible effects (VitalSleep).
• Go slowly. Advance a jaw device in small steps and stop at the lowest setting that works. More is not better.
• See a dentist first if you have TMJ problems, loose teeth, gum disease, dentures or major dental work.
• Stop and get checked if you have lasting pain, your bite feels different during the day, or your jaw locks.
• A quieter night isn’t a clean bill of health. If you still wake up tired, get a sleep test.

Try the free fixes first

Side-sleeping, alcohol timing and a clear nose cost nothing and help some snorers on their own.
