Dry mouth, empty glass, throat like paper every morning? Reviv is a flat guard your jaw rests on all night. Three sizes, no mold — in after you brush. 30K+ people sleep with one.
Mouth Breathing Support
At night your jaw lets go completely. It drops. And your mouth falls open with it. Reviv puts a flat plane between your upper and lower teeth. Your jaw settles onto it instead of hanging free. Nothing grips. Nothing pulls.
The elbow. The nudge. The "you were doing it again." Whoever shares your bed has the full report: the open mouth, the light snore, the 3am dry-throat cough. If your mornings are the first clue, their elbow is the second. This page is for both of you.
Mouth tape holds your lips together. A chin strap pulls your chin up. Nasal strips sit on your nose. All three work on the outside of your face. Any one of them can come loose by 3am, and you never feel it happen.
Reviv sits inside, between your teeth, where your jaw actually rests. Your bite holds it in place. It's doing the same job at 4am as it was at 11 — all night, every night. Some people wear it ten hours. Some put it in while they read.
Ken founded Reviv after 10+ years of experimenting on himself. His theory is simple: your mouth doesn't fall open on its own — it gets dragged open by a jaw with nowhere to rest.
Give the jaw a level surface and it settles there for the night. That's the whole product. Not a seal, not a strap — a resting place. What that does for your mornings, you'll feel for yourself.
Tape is a roll you finish and re-order. Strips are a box you finish and re-order. Reviv arrives ready to wear in one of three sizes — no boiling, no molding, no appointment.
$80 is the whole cost, shipping included, with a 1-year replacement warranty. No renewal. No surprise charge on your card. It packs in a weekender. Nobody ever finds out unless you say so.
A 3,000+ member community shares the routine. Every R3 guard comes with a 1-year replacement warranty. Yours arrives. You use it that night.
"I snored. Dry mouth every morning, water on the nightstand like clockwork. The first few nights I lasted maybe two hours before it came out — nobody warns you about that part. I worked up to full nights over a couple of weeks. Mornings feel different now. I'll leave it at that."
