Ken Leaver
Reviv Founder
"In 2020 I was exhausted by 6pm and got sick a couple times a year. For the last two years at the age of 47 I work from 8am till past 10pm everyday without burning out. I haven't been sick in over four years and I feel like a beast everyday."
"I need less and less sleep to function better and better with this thing. It's crazy!"
Jules, Jan 2025"During the first night wearing the Reviv, I felt the muscle on the left side of my face relax, and yesterday was the first time i could chew food on the left side, the same as my right."
George, Jan 2025"After wearing Reviv i've been able to start getting my life and career back together and seen huge improvements like my brain fog has cleared for the most part and sleep quality and posture have gotten better."
Daniel, Jan 2025"As a result of my changes I have purchased Reviv for my whole family and a friend who is recovering from stage four ovarian cancer."
Meryl, Jan 2025"Using it as much as I can and in just two days I noticed some increased mental clarity and improved mood."
Tim, Jan 2025HOW REVIV WORKS
There are some basic biomechanics to how the skeleton and skull work, which result in it collapsing over time.
Particularly if you did orthodontics, extractions, or grind your teeth because those things flatten your 'curve of spee', which is the natural curve of how your upper & lower teeth make contact.
And Reviv essentially reverses that collapse, thereby reinflating the skull and skeleton back to their healthy state.

Addresses TMJ
"I've been wearing my appliance for 3 weeks now. No more TMJ pain at all! I can do chin tuck exercises without my neck muscles spasming and cramping." - Jay

Gives you back energy
"I wear it when driving the bus. A day of work that normally knocks me out the next day had me full of energy. Even when i got home after a very long day. I love this thing!" - George

Eliminates brain fog
"Although i'm a software developer I spent about a year carrying boxes in a warehouse because of the thick brain fog i had. I've been wearing Reviv since early November and brain fog is gone. I just recently started a job working as a developer again!" - Ivan

Fixes Posture
"I noticed the other day the area where my neck meets my upper back is more flat . I always had a bit of kyphosis and rounded soldiers and it seems to be correcting." - Harvwin

Guess what the easy cure to sleep apnea is?
I'll give you a hint... it is not a CPAP!

My bite is uneven... will a mouthguard help?
Yes, it will. The reason lies in the physics of how the skull expands and contracts.

Teeth must move for the Reviv process
So my recommendation is to AVOID wearing braces, aligners, or retainers while undergoing the Reviv process.

Why does this work?
Think of the soft tissue (e.g., fascia & skin) covering the bones of the skull as a balloon. When you grind your teeth down, it is as if you're taking air out of the balloon.
When this balloon deflates, it crushes the skull, which in turn crushes the brain and causes cognitive and neurological issues over time.
In general, we as a society like to call this process 'aging.' But if you grind down your teeth faster, you 'age' faster. The good part is you can reverse the process by using the same physics in reverse, i.e., you 'add' height back to the teeth.
How many people have done this process?
About 500 people have been using the appliance and this method starting early 2023.
How does sizing work?
Generally we think most folks should get a large size appliance.
If you have a smaller mouth than we recommend you get a small. We only have two sizes.
Is this similar to "Mewing"?
While "Mewing" has some of the same benefits and leverages some of the same mechanics, Ken's view is that this approach is far more efficient (ie. faster) than Mewing.
Also it will work for a far higher percentage of folks than Mewing will.
In fact it should work on everyone, which is why there is the guarantee.
