The Science Behind It
Every night, your tongue naturally relaxes as you fall asleep, and for most people it drops down and back, losing contact with the roof of the mouth. You're asleep for the whole thing, so you've never once seen it happen, and it's almost certainly never come up with anyone treating you.
Once your tongue has dropped back, it's sitting in your airway. The air you're breathing has to force its way past, and air squeezing through a narrowed space makes the soft tissue around it vibrate. That vibration is the sound your partner hears. Your mouth then falls open to get more air around the blockage, which dries your mouth out overnight and makes the sound louder. It's also why the snoring is worse when you're on your back, because gravity pulls your tongue back further still.
That's why we designed Restflow around tongue position, not around sealing your lips or forcing air past the blockage. By gently holding the tongue forward against the palate, nothing drops into your airway in the first place, so there's nothing for the air to squeeze past and nothing left to make the sound. No tape, no mask, no machine, and nothing to force.
There's one thing that can still work against it, which is your nose. If your nasal passage is even slightly blocked, your mouth will try to fall open to breathe around it, and the moment your lips part your tongue loses some of the support the retainer is giving it. That's why every order comes with a free 30 day supply of nasal strips. They hold your nasal passage open so there's enough air coming through your nose that your mouth has no reason to fall open at all. The retainer holds your tongue forward, the strips keep your nose clear, and the two together mean you breathe through your nose all night with nothing sitting in your airway.

Is It Safe?
Yes. Restflow is made from soft, medical grade silicone and doesn't force your tongue or jaw into a new position. It sits low and forward in your mouth, nowhere near the back of your throat, so there's no choking or gagging feeling, and it can't move backwards while you're asleep.
The biggest difference from mouth tape is that your mouth isn't sealed. Tape holds your lips together, and if you have a cold or your nose blocks up in the night, you're stuck with it. Restflow leaves your mouth free the whole time. If you ever need to open it, you just open it. Nothing is stuck to your skin, there are no straps, no mask over your face and no pressurised air, so there's nothing to panic about at 3 in the morning.
Most people find it comfortable within the first few nights. It feels unusual for the first 5 or 10 minutes and then you stop noticing it. If you've never used a tongue positioning device before, wear it for an hour or two while you're reading or watching something before you wear it for a full night.
How Does It Work?
Every night, your tongue naturally relaxes as you fall asleep, and for most people it drops down and back instead of staying against the roof of your mouth. It ends up sitting in your airway, so the air you breathe has to force its way past, and that squeezing is what makes the sound your partner hears through the wall.
Restflow gently holds your tongue forward in the position it's supposed to be in, so it never gets the chance to drop. Nothing sits in your airway, so there's nothing for the air to squeeze past and nothing left to make the sound. No mouth tape, no mask, no machine, and nothing being forced.
Every order also comes with a free 30 day supply of nasal strips, and they're there for one specific reason. If your nose is even slightly blocked, your mouth will try to fall open to breathe around it, and the moment your lips part your tongue loses some of the support the retainer is giving it. The strips hold your nasal passage open so there's enough air coming through your nose that your mouth has no reason to open at all. The retainer handles your strips hold your nasal passage open so there's enough air coming through your nose that your mouth has no reason to open at all. The retainer handles your tongue, the strips handle your nose, and together you breathe through your nose all night with nothing sitting in your airway.
FAQ
Is It Uncomfortable?
No. Soft, medical grade silicone with no straps, no hard edges and nothing on your teeth or stuck to your skin. It feels unusual for the first 5 or 10 minutes and then you stop noticing it. Most people are sleeping through the whole night by night 2 or 3.
How Is This Different From Mouth Tape?
Mouth tape only seals your lips shut. It does nothing for your tongue, which is why people try it and still wake up with the same saggy, tired look, or their tongue still sitting at the bottom of their mouth. Restflow holds the actual muscle that matters, your tongue, in the position that supports your jaw. No tape, no straps, nothing sealing your mouth shut.
Can I Use This Instead Of My CPAP?
A lot of our customers came to us for exactly that reason. They were sent home with a machine, never got on with it, and it ended up in a cupboard. Restflow works on the root cause of the snoring instead of forcing air past it, so there's no mask, no straps, no noise, nothing to plug in and nothing to wash out every morning. It goes in your mouth, you sleep, and it comes out.
How Quickly Will I Know If It's Working?
Faster than you'd expect, and you won't have to judge it yourself. Most women get told by their husband next to them inside the first 3 nights, usually before they've mentioned they were trying anything. The dry mouth in the morning tends to go on the very first night.
What If I Try It And Don't Like It?
You get every cent back. 60-day money-back guarantee, no questions asked, nothing to return.
What Real Customers Are Saying
Recommended by leading specialists
These are physicians who don't recommend sleep devices lightly, and only recommend this one because it works on the tongue dropping back into the airway, the root cause they see behind almost every case of snoring.
I've assessed hundreds of patients for tongue posture and snoring. Restflow is the first device soft enough to wear all night while still holding the tongue against the palate, which is exactly where the snoring starts. For patients asking what to do after mouth tape hasn't worked, this is what I recommend first.
I see patients spend hundreds on CPAP machines and mouth tape that never touch the actual root cause. Restflow addresses tongue position directly, the same mechanism we target in airway therapy, just in a simple at-home form. In 12 years of practice, this is the first product in this category I've told patients to try before a formal sleep study or a CPAP machine.
The snoring my patients describe after 50 isn't just age, it's years of the tongue dropping back into the airway every night and never being corrected. Restflow is the first at-home product I've seen with real structural logic behind it. I recommend it to nearly every patient who asks about snoring before we ever discuss a machine.
What Sets Restflow Apart?
Almost everything sold for snoring is aimed at your lips, your nose or your jaw, and none of those are where the sound actually comes from. Here's why Restflow is built differently:
Targets the Root Cause
Mouth tape holds your lips together, a chin strap holds your jaw shut, and a CPAP forces air past the blockage. Not one of them moves the thing that's actually sitting in your airway. Restflow works differently: it holds the tongue itself in place, so nothing drops back, nothing narrows, and there's nothing left for the air to squeeze past.
No Tape, No Force
Unlike mouth tape or a CPAP mask, Restflow doesn't seal your lips shut or strap anything to your face. Your mouth stays free all night, so if your nose blocks up you can simply open it. There's nothing to override, just gentle, passive support for your tongue.
Custom, Secure Fit
Made from soft, medical-grade silicone that adapts to your mouth's shape, Restflow stays securely in place through the night, solving the "peels off overnight" problem common with mouth tape.
Reusable & Built to Last
Restflow is designed for long-term use, not single-night disposal, a durable, easy-to-clean device that delivers real value over dozens of uses, not just one.
Why Restflow Works Differently
CPAP
- Does stop the snoring while you're wearing it
- Forces air past the blockage, doesn't move your tongue
- A mask, straps and a machine by the bed every night
- Costs $500 to $1,000, plus parts to replace
Mouth Tape
- May help you breathe through your nose
- Does nothing for your tongue position
- Often peels off overnight
- Cheap per unit, but you're buying it constantly ($10-30/month)
Restflow
- Gently holds tongue forward, supporting your jaw, airway, and jawline all night
- Addresses the root cause, not just the symptom
- No straps, no tape, nothing forcing anything
- Only 1% return rate, people actually keep using it

Place Restflow in your mouth with the rounded end facing back and gently create a light suction with your tongue against the device. It should feel secure but never tight - if it feels like it's pinching or pulling, remove it and reposition. Most people take a few nights to get used to sleeping with it in. We recommend wearing it for short stretches during the day first (even while reading or watching TV) so your mouth adjusts before you rely on it overnight.

No. Restflow doesn't touch your teeth or reposition your jaw at all, it works entirely by holding the tongue itself forward. This is the key difference from snoring mouthpieces and chin straps, which drag your lower jaw forward or hold it shut from the outside for 8 hours, and can leave you with jaw soreness, clicking, or a bite that feels off in the morning. There's nothing rigid pressing against your teeth or jaw with Restflow, so there's no risk of that kind of strain.

Most women get an answer inside the first 3 nights, and usually from the person next to them rather than by noticing anything themselves. The dry mouth in the morning tends to go on the very first night, because your mouth simply isn't falling open any more. By around week 2, most partners have stopped getting up in the night at all. Everyone's timeline is a little different, but consistency matters more than speed, wearing it every night is what makes the difference hold.
