Your Jaw Works the Night Shift. Reviv Gives It a Break.
You spend a third of your life asleep, and for those seven or eight hours your jaw sits wherever it falls. For a lot of people that means clenching, a collapsed bite, or a lower face that stays tense all night long.
You might put real effort into your posture, your tongue position or your jawline during the day, and then lose it overnight without realizing.
The Reviv mouth guard was made for those hours. It gives your teeth a soft, even surface to rest on so your jaw can settle into a relaxed position while you sleep, night after night.

What Is the Reviv Mouth Guard?
The Reviv mouth guard is a nighttime mouthguard built on one simple idea: give your jaw a better place to rest while you sleep.
Most night guards are hard, custom-molded trays that lock your teeth into one fixed bite. Reviv takes a different approach. Its flat-plane silicone design gives your teeth a smooth surface to glide on, so your jaw can find its own comfortable rest position instead of being held in place.
It's soft, it's ready to wear the day it arrives, and it fits into your routine in seconds: brush, put in Reviv, sleep. That's why Reviv has become a go-to for people working on jaw posture, tongue posture (mewing) and overall posture, as well as anyone who wakes up with a tight, tired jaw.
How the Reviv Mouthguard Works While You Sleep
There are no exercises to remember and nothing to adjust. Put it in, go to sleep, and let Reviv do its job.
Adds soft height
A layer of soft silicone between your upper and lower teeth is designed to stop your jaw from clamping shut overnight.
Relaxes the lower face
With your bite no longer collapsing, the muscles of your jaw and lower face get a chance to rest while you sleep.
Lets your bite glide
The flat-plane surface means your teeth slide rather than lock into a slot, so your jaw settles where it's comfortable.
Protects your progress
Jaw, tongue and head position are connected. Reviv helps your daytime posture and mewing work carry through the night.
