You know you clench.
You may not know what it costs your morning.
You have felt it: the tight jaw first thing, maybe a sore neck, a back that does not loosen until later, or the slow start where sleep did not feel like it fully helped.
Most people assume clenching is isolated. For a lot of people, the morning pattern feels bigger.

“I knew I clenched at night. I didn't realise it was connected to the tightness in my neck every morning until I started using this.”

“The fatigue was the part I couldn't explain. About six weeks in I started having mornings where I felt like I'd actually slept.”

Why the jaw can be
the starting point
Reviv’s Balloon Theory is a simple way to think about spacing and support. When the jaw settles into a tighter position overnight, the morning can feel tighter too.
R3 is designed to support a more consistent jaw position during rest — giving your nighttime routine one clear physical cue instead of asking you to chase every morning signal separately.

Support the structure
the clenching disrupts
- Supports a more natural jaw position overnight
- Helps create gentle separation while you sleep
- Gives your wind-down routine one consistent physical cue
Many people start because they notice clenching. What keeps the habit going is how simple it is: put the R3 in during wind-down or sleep, then let the routine repeat.

“I'd been to a physio four times in two years for my upper back. I started wearing the R3 eight weeks ago. My physio asked what I'd changed.”

Why one product addresses all of it
Ken (EGK) developed Reviv after discovering how jaw posture impacted his own sleep, recovery, and daily energy. The R3 is a structured mouthguard made from a flexible material designed to fit comfortably in your mouth. It's built to stretch the soft tissue and allow the jaw to naturally move where it wants — during sleep, while reading, while winding down.
Try It TonightFAQ
During sleep, or during wind-down before sleep, as part of your existing nighttime routine.
The R3 is flexible and designed to sit without boiling, moulding, or adhesive. Most people give themselves a few nights to adjust.
It varies. Some people notice their routine feels different quickly; others need several weeks of consistent use before they can judge it.
No product can guarantee that. R3 is designed to support jaw positioning overnight and make the routine more consistent.
No complicated setup. Wear it during sleep or wind-down and keep the routine consistent.
The R3 comes with a Satisfaction Guaranteed policy and a 1-Year Warranty.
You have been managing this for a while now.
The R3 isn't a guarantee. But it's the thing most people hadn't tried yet — and for a lot of them, it's the thing that changed what mornings feel like.
