The Science Behind It
Every night, your tongue naturally relaxes as you fall asleep, and for many people, it drops down and back, losing contact with the roof of the mouth. This has nothing to do with stress, or with how well you're coping. It happens silently, night after night, whether you notice it or not.
Without your tongue in place, your jaw has to clench and shift all night just to keep your airway from closing off, and that is where the morning jaw pain comes from. It's also where the headache behind your temples comes from, because the muscle doing that clenching runs up the side of your head. And because your mouth falls open to breathe around it, it's why you wake up with it hanging open and bone dry.
That's why we designed Restflow around tongue position, not exercises or willpower. By gently holding the tongue forward against the palate, it removes the one mechanical cause behind the clenching, no night guard, no splint, no injections. Just your tongue held in place, so your jaw has no reason to brace at all, all night, every night.

Is It Safe?
Yes. Restflow is made from soft, medical-grade silicone and doesn't force your tongue or jaw into a new position. Unlike a night guard, there's nothing sitting between your teeth for your jaw to bite down on, and it sits low at the front of your mouth, nowhere near the back of your throat, so there's no choking or gagging feeling.
It also doesn't hold your jaw open or push it forward the way a splint does, so it won't leave you with new clicking or soreness. It simply holds your tongue in its natural resting position, which is exactly what takes the pressure off your jaw in the first place, instead of adding any new strain to it.
Most people find it comfortable within the first few nights. If you're new to using any tongue-positioning device, we recommend easing in with shorter use before wearing it a full night.
How Does It Work?
Every night, your tongue naturally relaxes as you fall asleep, and for many people, it drops down and back instead of staying against the roof of your mouth. This happens silently, whether you notice it or not, and it's what forces your jaw to clench and shift all night just to keep your airway open, which is where the morning pain and the headaches behind your temples come from.
Restflow gently holds your tongue forward in that position, so it never gets the chance to drop. No night guard, no splint, no injections, just your tongue held in place, so your jaw has no reason to clench at all, all night, every night.
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.
Will This Help With Jaw Clenching?
For most people, yes. A lot of nightly jaw clenching happens because the jaw is trying to keep the airway open once the tongue drops back. By holding your tongue in place, Restflow removes that trigger, so many people notice less clenching and less morning jaw pain. It's soft and low profile, so it works fine on its own or alongside a night guard if you already wear one for your teeth.
How Is This Different From A Night Guard?
A night guard protects your teeth from the clenching after the clenching has already started. It was never designed to stop the clenching itself. Restflow works on the reason your jaw is clenching in the first place, by holding your tongue forward so your airway stays open and your jaw has no need to brace against anything. One protects your teeth from the damage. The other removes the cause.

What Real Customers Are Saying
"Best purchase I've made in years. My husband had been in the spare room on and off for nearly 2 years and mouth tape did absolutely nothing. A CPAP was the next step and I was dreading it. My husband said something on the third morning, before I'd even told him I was using anything. He hasn't slept in the spare room since. I had no idea my tongue dropping back at night was even the root cause. If you're on the fence, just try it."
Sarah T.
"Honestly didn't expect this to make much difference. I'd already had 2 night guards and a year of injections in my jaw, so I'd pretty much accepted that waking up sore was just how my mornings were going to be. A few weeks in and I woke up one morning and the ache just wasn't there. I didn't even feel any different wearing it, it's that comfortable, and there's nothing between your teeth the way there is with a guard. Simple and it just works. Can't recommend it enough."
Laura F.
"I wore a night guard for nearly 2 years and never got used to it - it wore through on one side, my jaw was just as sore every morning, and it did nothing at all for the headaches. This is the complete opposite experience. Nothing between my teeth, nothing to bite down on, nothing to replace every year like everything else I tried before. Just simple and it actually works. My husband noticed I'd stopped taking painkillers with my breakfast before I noticed it myself. Wish I'd found this before wasting money on guards and injections."
Katie M.
"My husband was the one who suggested I try this, after another morning of me holding the side of my face before I'd even had a coffee. I honestly wasn't convinced something this small could make a difference. A few nights in and I was waking up with my mouth closed for the first time in years, and the ache had gone within a month. Comfortable, easy to use, and it's become part of my routine without a second thought. Solid purchase."
Grace W.
"I'd been waking up with a sore jaw for a while and just chalked it up to stress. I tried a night guard, then a second one when the first wore through, and even looked into a thicker splint, but nobody ever explained why it was happening in the first place. After reading more into Restflow and how it actually targets the root cause instead of just the symptom, it finally made sense. A few weeks in and I'm waking up without the ache. Comfortable, easy to use, and I wish I'd found this before wasting money on everything else."
Amber L.
"My dentist had quoted me $900 for a thicker splint and I already had the appointment booked. I cancelled it after 3 weeks on this. The morning headaches were honestly worse than the jaw itself and they were the first thing to go. I was worried it would feel strange having something in my mouth at night, but I genuinely forget it's there now. The cheapest thing I've tried and the only one that's actually done anything."
Molly B.
THE CLINICAL VERDICT
Recommended by leading specialists
These are physicians who don't recommend sleep devices lightly, and only recommend this one for jaw pain, morning headaches, and waking up with your mouth open, the 3 problems they see coming from the exact same root cause.
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.

Most of the jaw clenching I see isn't a dental problem at all, it's an airway problem. When the tongue drops back, the jaw has to brace to keep the airway open, and that bracing is what patients feel in the morning. 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.

I've fitted more night guards than I can count, and I'll be honest with you, they protect teeth, they don't stop clenching. Nothing I make in a lab does. Restflow is the first at-home product I've seen that works on why the jaw is clenching rather than on what the clenching is doing to the teeth. I now raise it with patients before we ever discuss a thicker splint.

What Sets Restflow Apart?
Almost everything sold for jaw pain is aimed at your teeth or at the muscle doing the clenching, and neither of those is where the clenching actually starts. Here's why Restflow is built differently:
Targets the Root Cause
A night guard puts plastic between your teeth. A splint puts thicker plastic between your teeth. Botox weakens the muscle that's doing the clenching. Not one of them changes why your jaw is clenching in the first place. Restflow works differently: it holds the tongue itself in place, so your airway never narrows and your jaw never needs to brace against anything.
Nothing Between Your Teeth
Unlike a night guard or a splint, Restflow doesn't sit between your teeth and it doesn't hold your jaw in a fixed position. There's nothing to bite down on and nothing pushing your jaw anywhere it doesn't want to go. 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. No mould taken, no fitting appointment, and no waiting 2 weeks for a lab to make it.
Reusable & Built to Last
Restflow is designed for long-term use, not something you replace when it wears through. A durable, easy-to-clean device that keeps working night after night, instead of one more thing to rebuy every year.
Why Restflow Works Differently
NOT IDEAL
Night Guard
- Does protect your teeth from the damage
- Cushions the clenching, doesn't stop it
- Wears through and needs replacing every year
- Costs $600 to $900, plus a mould and a fitting appointment
NOT IDEAL
Botox
- Does ease the muscle for a while
- Weakens the muscle, doesn't stop the jaw bracing
- Wears off after about 3 months and the ache comes back
- Around $400 to $800 every single time, forever
BEST CHOICE
Restflow
- Gently holds your tongue forward, so your jaw has no reason to clench all night
- Addresses the root cause, not just the symptom
- Nothing between your teeth, nothing forcing your jaw anywhere
- Only 1% return rate, people actually keep using it

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 a night guard or a splint is that nothing sits between your teeth and nothing holds your jaw in a set position. A splint that pushes your jaw forward can leave you with new clicking or soreness, because it's moving a joint that's already under strain every night. Restflow doesn't touch your jaw at all. It works on your tongue, and your jaw is simply left alone to relax.
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. -
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. Your airway starts to narrow behind it, and your jaw has to clench and shift all night just to keep that airway open. That bracing is what you feel the next morning.
Restflow gently holds your tongue forward in the position it's supposed to be in, so it never gets the chance to drop. Your airway stays open, so your jaw has no reason to brace against anything all night. No night guard, no splint, no injections, and nothing being forced.
Every order also comes with a free 60 day supply of nasal strips, and they're there for one 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. Your jaw goes straight back to bracing, which is the exact thing you're trying to stop. The strips hold your nasal passage open so your mouth has no reason to open at all. The retainer handles your tongue, the strips handle your nose, and together your jaw gets to stay relaxed all night. -
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 their first answer on the very first morning, when they wake up and their mouth isn't dry, because it simply hasn't been falling open all night. The headache behind your temples usually eases next, often lifting hours earlier in the morning within the first week or 2. The jaw itself takes the longest, because that muscle has been bracing every single night for years and it needs time to stop, so most people are looking at around 6 weeks before the ache has properly gone. Everyone's timeline is a little different, but consistency matters more than speed, wearing it every night is what makes the difference hold.
-
A lot of our customers came to us for exactly that reason, 2 or 3 guards in and still waking up sore every morning. You can use Restflow on its own, or keep wearing your guard alongside it if you'd rather carry on protecting your teeth while you get used to it. They sit in completely different places and don't interfere with each other. The difference is that a guard protects your teeth from the clenching, and Restflow works on the reason your jaw is clenching in the first place.
