"I used to wake up with my tongue feeling like a piece of dry wood in my mouth. No more."
— Michele M
Three steps. Two weeks.
Most users feel the difference from the first night. Full all-night wear takes 1–2 weeks as your tongue and jaw adjust. That's normal — and the customers who push through are the ones who tell us they can't sleep without it now.
Rinse & place
Quick rinse with warm water, then position between your teeth and lips. Gently bite down on the shelf area. No molding, no fitting required.
Light tongue suction
Your tongue will naturally rise to the roof of your mouth. A gentle suction will occur, positioning your tongue in an ideal position for nasal breathing.
Give it a week
Expect a learning curve. Some drool, maybe finding it on your pillow once or twice. By night 7–14, most users forget they're wearing it.
Is it right for you?
NoseFlow works for most people most of the time — but not everyone. Here's an honest look at who benefits most, and who should look elsewhere.
Built for you if
- You wake up with a dry mouth or scratchy throat
- You snore (or your partner says you do)
- You're a CPAP user dealing with mask leaks or dry mouth
- You use mouth tape but hate the adhesive — or you have a beard
- You grind your teeth at night
- You want something reusable instead of disposable tape
What it's not
- It's not a quick fix — most users need 1–2 weeks to adjust
- It's not mouth tape — it trains tongue posture, not forced lip closure
- It's not a treatment for sleep apnea — see a doctor for that
- It's not for braces, active aligners, or recent oral surgery
- It's not for everyone — which is why we offer 30-day returns
What customers say
Lowest CPAP leakage rate yet
This has been a real change for me after struggling on my CPAP journey for months with all kinds of masks leaking air. Tried tape, neck bracing, special CPAP pillow, chin strap, nothing could prevent my mouth leaking. It's very comfortable to wear with any of my masks and so affordable.
Off my CPAP machine
This product does much more than advertised. I've gotten rid of my CPAP machine, because I no longer breathe through my mouth at night. Highly recommended for apnea sufferers that breathe through their mouth at night.
Finally something that worked
I have been a mouth breather all my life. I'm 68. I don't sleep well and have a dry mouth all night. I have tried so many different guards, but they didn't work. I am so very thankful that I found this. It's so comfortable. I sleep great and no dry mouth.
Tried everything. This worked.
I have tried a lot of different things to help me breathe through my nose at night — chin straps, tape, elevated pillows. Nothing worked as well as this does. It helps you get your tongue in the right position and creates a seal so your mouth stays shut while you sleep.

It can, especially in the first 1–2 weeks before your tongue learns to hold the suction. Most users report it stays in consistently after an adjustment period. If it keeps slipping out after two weeks, email us — we're always happy to help.
Most users feel a difference the first night — less dry mouth in the morning. Consistent all-night wear typically takes 1 week as your tongue and jaw adapt.
Some users experience mild soreness in the first few days, similar to wearing a new retainer. This usually resolves as you adjust. If discomfort persists, the silicone can be trimmed with scissors to better fit your mouth.
Maybe, especially the first few nights. Your mouth produces extra saliva when adapting to anything new inside it — this subsides as you adjust. After about a week, most users don't notice it anymore.
No. Mouth tape physically holds your lips shut from the outside. NoseFlow works differently — it guides your tongue into the position that naturally encourages a lip seal and nasal breathing. It's reusable, works with facial hair, and doesn't leave adhesive residue. Customers who tried both often prefer this.
It depends. Many of our happiest users are CPAP users. It works especially well with nasal pillow and nasal-only masks, where it helps reduce air leakage through the mouth. Always check with your sleep doctor before changing anything about your CPAP therapy.
