Your snoring has a setting. Most mouthpieces guess it. VitalSleep lets you find it.
Snoring starts when your lower jaw drops back during sleep and narrows your airway. How far forward your jaw needs to move to open it is different for every person.
One-position mouthpieces pick a spot and hope. VitalSleep's patented Accu-Adjust System moves your jaw forward one millimeter at a time, from 0 to 8 mm, so you find the exact spot where your airway stays open and the room gets quiet.
★★★★★ 4.6/5 from 1,100+ verified reviews · 600,000+ sold since 2011
Will it work for me?
If your snoring comes from the throat (most does), holding the jaw forward is the fix. You get 60 nights to adjust it and judge. If it is not quieter, you get your money back.
What if the fit is not right?
Wrong size? Free size exchange. Fit did not take? Free replacement. One-year unlimited warranty on top.
Is it hard to get used to?
The first two or three nights feel new. Most people stop noticing it within a week. Start at a low setting and move up slowly.

Why "adjustable" is the whole game
1. Snoring is a jaw problem
When you fall asleep, the muscles in your throat relax. Your lower jaw and tongue slide back. The airway gets narrow. Air pushes through and the soft tissue vibrates. That is the sound.
2. The fix is a position, not a product
Hold the lower jaw slightly forward and the airway opens. But the right amount is personal. One person is quiet at 2 mm. Another needs 6. Too little and you still snore. Too much and your jaw aches.
3. So you need to be able to dial it in
VitalSleep is the mouthpiece built around that fact. Mold it to your teeth, then use the included key to move the lower tray forward 1 mm at a time until the snoring settles down. Back it off if you want more comfort.
Sounds simple. Here is the proof that it works, and that it can work for you.
Where the noise comes from
Jaw back. Tongue falls toward the throat. Airway narrows. Tissue vibrates. You snore.
Jaw forward. Tongue comes with it. Airway opens. Air moves quietly.
This is why pillows, sprays, and nose strips so often disappoint. They work on the nose or the neck. The blockage is behind the tongue. A device that holds the jaw forward works on the actual spot.

One position for everyone is a guess
Most drugstore and online mouthpieces hold the jaw in a single fixed spot. The maker picked it for the "average" mouth. You are not average. Nobody is.
- Set too short and the airway never opens enough. You wear a mouthpiece and still snore.
- Set too far and you wake with a sore jaw and quit after a week.
- Can't change it, so your only options are to keep trying or throw it out.
Years of customer messages taught us the same thing: the two reasons people give up on a mouthpiece are "it didn't help" and "it hurt." Both are position problems. Both are what adjustment fixes.
The Accu-Adjust System: find your setting, 1 mm at a time
The lower tray of VitalSleep sits on a patented track. A small included key moves it forward or back in one-millimeter steps, across a range of 0 to 8 mm. You set it. You can change it. You can change it again.
- Start low. Begin at 0 or 1 mm. Comfort first.
- Move up 1 mm. Give each setting two or three nights. Ask your partner how it went.
- Stop at your quiet point. Many people settle somewhere in the middle of the range. That number is yours.
- Back off anytime. Jaw feels tight? Turn it back one step. The device adapts to you, not the other way around.
Watch how the lower tray moves to open the airway (0:16).
Set it yourself. Change it anytime.

Molds to your teeth in about five minutes
An adjustable tray only helps if the mouthpiece stays put. VitalSleep uses a boil-and-bite fit. Warm it in hot water, bite down for 30 seconds, and the soft inner layer takes an impression of your teeth.
- Grips your upper and lower teeth, so the jaw stays where you set it
- No dentist visit, no impression kit, no waiting weeks
- Air holes in the front let you breathe through your mouth if your nose is stuffy
- BPA-free and latex-free materials, made in the USA
Fit plus adjustment is the combination. Fit keeps it in place. Adjustment makes it work for your airway.
Jaw-advancing mouthpieces are one of the most studied answers to snoring
VitalSleep belongs to a class of devices doctors call mandibular advancement devices. Independent researchers have been testing that class for decades. Here is what they found.
FDA-cleared
VitalSleep is an FDA-cleared Class II device for snoring. It is not a gadget from a marketplace listing.
600,000+ sold since 2011
Fifteen years of making one product, and improving it, instead of white-labeling someone else's.
Patented design
The Accu-Adjust System is patented. Other mouthpieces cannot copy the way it moves.
Study results describe the device class, not VitalSleep specifically. Individual results vary.
People who tried the others, then stayed with this one
"I've been using this device for 10 years now. I tried 2 other brands in that time just out of curiosity but came back to the VitalSleep and am a satisfied user."
"I have had multiple vitalsleep devices over the years. It is the only device that I tried that really works."
"It works great! I have it on #4 setting now. It took a few adjustments to get it just right. It only took me a few night's to get use to it."

Individual experiences. Results vary.
What the first two weeks look like
Nights 1 to 3
It feels new. More saliva, a little jaw awareness in the morning. Normal. Many partners already notice a quieter room.
Week 1
You stop noticing it. You have moved the tray up a step or two and found the spot where the snoring settles.
Week 2 and on
Your setting is set. You wake up with more energy and your partner stops reaching for the earplugs.
Not there yet? You have 60 nights to adjust and judge. If it is not quieter by then, you get your money back.

Questions people ask before ordering
How is this different from a fixed mouthpiece?
A fixed mouthpiece holds your jaw in one spot picked by the maker. VitalSleep lets you move the lower tray 1 mm at a time from 0 to 8 mm, so you set the position that works for your airway and your comfort.
How do I know which setting to use?
Start at 0 or 1 mm. Move up one step every two or three nights until the snoring settles. If your jaw feels tight, turn it back one step. Many people land somewhere in the middle of the range.
Will it fit my mouth?
You mold it to your teeth in about five minutes with hot water. Choose Men's or Women's Size. If the first size is wrong, the exchange is free. If the fit does not take, the replacement is free.
Can I breathe through my mouth with it in?
Yes. The front has air holes so you can breathe through your mouth if your nose is stuffy.
Does it treat sleep apnea?
No. VitalSleep is FDA-cleared for snoring. If you have been diagnosed with sleep apnea, or you stop breathing in your sleep, talk to your doctor before using any mouthpiece.
What if it does not work for me?
You have 60 nights to adjust it and judge. If it is not quieter, contact us for a full refund. Returns and exchanges are free.
How long does one last?
With normal nightly use, about a year. It is covered by a one-year unlimited warranty, and it is a one-time purchase with no refills or subscription.

VitalSleep is an FDA-cleared Class II device intended to reduce snoring. It is not intended to diagnose or treat sleep apnea or any other condition. Individual results may vary. Talk to your doctor or dentist if you have questions about whether an oral appliance is right for you.
Which size should I order?
Most men order Men's Size. Most women order Women's Size. It is about 10% smaller. Both mold to your teeth, so the size is about the tray, not a perfect match.
| Size | Length | Width | Height |
|---|---|---|---|
| Men's | 2.66 in / 67.5 mm | 1.97 in / 50.1 mm | 0.84 in / 21.4 mm |
| Women's | 2.41 in / 61.1 mm | 1.88 in / 47.7 mm | 0.94 in / 23.9 mm |
- Wrong size? The exchange is free.
- Small mouth or small frame? Choose Women's, whoever you are.
