You've optimised your training.
Your sleep. Your nutrition.
But not this.

Most athletes never consider jaw position as part of their recovery stack. Reviv is built to support natural jaw alignment overnight — so you wake up with less tension, more mobility, and a body that's ready to move.

The variable most athletes
never track

Athlete stretching on field with mouthguard

Your jaw is connected to your neck, spine, and the base of your skull. When jaw position is off during sleep, it creates tension that travels through your neck muscles, into your upper back — and stays there when you wake up.

Reviv is built to stretch the soft tissue and allow the jaw to naturally move where it wants — during sleep, so the tension that builds overnight has somewhere to release.

Many athletes who start using it notice they wake up looser. Less time spent on the warm-up mat. More range of movement from the first set.

Results vary. Designed to support overnight jaw alignment and recovery.

What changes when jaw alignment is part of your routine

  • A shorter window between waking up and feeling loose
  • More consistency in how your body feels before training
  • A recovery input that works while you sleep — no extra time required

the variable they'd missed

“I'd been dealing with neck tightness for a long time — tight every morning, had to spend ages on it before I could train properly. I started using Reviv about six weeks ago and the mornings have genuinely changed. Not dramatically, but consistently. I notice it most on back-to-back training days.”

“Honestly I was sceptical. I didn't connect jaw tension to neck stiffness at all. After a few weeks with Reviv, my jaw feels a lot less clenched when I wake up, and the neck tightness has eased. I wear it during workouts too now.”

“I travel a lot for competition so my sleep is already inconsistent. I started using Reviv as part of my wind-down routine — it's simple, takes nothing to add in. First night I could feel a difference in how my jaw sat. Stuck with it since.”

“I've tried a lot of recovery tools — foam rollers, compression, cold exposure. Most of them I rotate in and out. The R3 I've used every single night for four months. It's the quietest thing in my stack and probably the most consistent.”

Reviv R3 benefits

The R3 — what it is
and how it works

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.

Most mouthguards are built to guard or hold. The R3 is built differently — the flat surface is designed to release the anchor points where your teeth connect, allowing the jaw to decompress naturally during rest.

You wear it overnight. It requires no fitting, no boiling, no adjustment. It becomes part of the routine quickly — most people adapt within a few nights.

Designed to support natural jaw positioning. Not a substitute for professional care.

Everything you need

One addition to your recovery stack.
Works while you sleep.

A nightly input that supports natural jaw alignment — no extra time, no new protocol.

Reviv Founder Ken Leaver

Why Ken built this

Ken (EGK) developed Reviv after noticing that his sleep, recovery, and energy were improving — without changing his training. He traced it back to jaw position. The R3 came from that discovery: a tool built to support what the body naturally wants to do overnight, for athletes who leave nothing to chance.

Questions before you try it

The R3 is designed for overnight use — wear it while you sleep. Some people also use it during low-activity downtime like reading or winding down before bed. The longer it's in, the more opportunity the jaw has to decompress.
Most people notice a change in how their jaw feels within the first few nights. Changes in morning stiffness and neck tension tend to become more consistent after 2–3 weeks of regular use. Individual results vary.
The R3 is made from a flexible material that sits lightly in the mouth. Most people adapt within the first few nights. It's not a bulky guard — it's designed to be worn consistently without disrupting sleep.
No. The R3 doesn't require boiling, moulding, or any fitting process. It's ready to use out of the box and designed to work without custom adjustment.
The R3 is designed to stay in place during normal sleep movement. If you find it isn't staying in through the night initially, most people find it improves after a short adaptation period.
Yes. The R3 is designed to work as part of a recovery routine, not instead of one. Most athletes use it alongside their existing stack — it adds a recovery input that works passively while you sleep.
We stand behind the R3 with a Satisfaction Guaranteed policy and a 1-Year Warranty. If you have questions or concerns, the support team is available to help.
