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."
HOW REVIV WORKS
We believe there are some 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 our experience is that this could result in the skull sort of 'deflating'.
And a simple mouthguard like Reviv can 'reinflate' it by stretching the soft tissue that covers the skull.
Jaw issues
"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
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
Mental Clarity
"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
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

How should I start Reviv? Is there anything to be aware of?
Yes there are a few things to know going in.
On wearing it: The standard pattern is overnight + 2-3 hours during the day. Build up gradually with shorter intervals during the day first rather than going straight to overnights — that helps the soft tissue adjust. Most folks find the early phase is the hardest part and it gets significantly easier after a few weeks usually.
On early discomfort: Pretty common in the first few weeks. Sore teeth, achy gums, occasional small sores in the mouth, the lips not closing fully, extra saliva — all signs the soft tissue is stretching, not signs something is wrong. Take it at your own pace. If the soreness gets sharp, take a short break — a few hours or even a day or two off is fine. Stick with it but don't push through pain.
On accelerating results: What matters most is consistent use and then stretching to accelerate. The Fast Method in our Skool community has some stretches we recommend, including the Bite & Hold exercise that works alongside the mouthguard: https://www.skool.com/reviv-2885/classroom/8ca49f79?md=90728adac0e5463680dc40a43e294104
On mouth taping: A lot of folks tape at night to keep the mouth closed and help with guard retention while the tissue is still adjusting. Pairs well with the Reviv.

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?
Over 20,000 people have started using the appliance and this method since late 2024.
How does sizing work?
Note that there is a 'Size Chart' above that you should refer to for measurements of our appliances.
We generally recommend adults to get a large as our large is not that large and our small is pretty small.
- The small can be used for children from about age 8 and up.
- Most adults with a smaller mouth will be fine with a small or a large, but will generally get a bit more of a stretch with our large.
- We have a special offer to get both sizes for the same price when purchasing the support package. So write to cs@getreviv.com if you want instructions on how to do that.
What is support?
When you purchase the 1-year support package you get access to:
