The Problem

People today are having more physical and mental health issues than ever before

Postural issues

Depression and Anxiety

Chronic fatigue and poor energy

ADHD, OCD, etc.

Obesity

The traditional ways of fighting these things is falling way short

Pharmaceuticals

Diet / Eating healthy

Exercise

Medical procedures

We at Reviv believe that there might be a structural root cause

There is essentially a set of physics that hold the body up and teeth play a critical role in this

Because of these physics the skull can essentially collapse inwards due to changes in the teeth

The health of the skull is reflected by the quality of the curve of spee (how the upper and lower teeth come together)

Orthodontics, extractions and grinding result in the flattening of this curve of spee

We believe the skull can be inflated like a ball

A simple mouthguard addresses this structural collapse at its root cause

The mouthguard acts like a doorstop that prevents the jaw from closing

This stretches the soft tissue in the mouth and covering the skull

When the soft tissue stretches the skull inflates and the skeleton untwists

The teeth correct as a function of the skull correcting

The cranial bones move outwards into better symmetry, the jaw moves to where it should be

The teeth are connected to the bones & jaw, and so they 'go for the ride' and straighten as a result

The body will function better and be stronger and more flexible as a result

Reviv makes three big hypotheses about the future of biomechanics:

Root cause of almost all disease

Is disease a function of biomechanical collapse?
Root cause of aging

If we don't collapse, maybe we don't die?
Root cause of beauty

Can we look like a model if we take this to the end?

What should I expect from doing Reviv?

1 Week

Likely some initial discomfort in the teeth and gums
May take a few nights to get used to sleeping with it

1 Month

The mouthguard is starting to get more comfortable
You might notice some differences in how your teeth fit together
Many users find their jaw feels less tense in the mornings
You may notice you're waking up without the tight, clenched feeling

1 Month

1 Year

You will likely function better (concentration, ability to handle complexity, etc)
There's a good chance you have more energy and stamina than in years
You probably will look better than you have in years

2 Years

The mouthguard alone has plateaud but you're doing the 'fast method' stretches that are recommended in the community
Things just keep improving functionally and aesthetically
It seems almost difficult to get sick and you seem to be in a good mood naturally most of the time

2 Years

Beyond 2 Years

You're playing for the 'end'
Does this process really go as far as this crazy guy, Ken, thinks it does?

I’ve been waiting for this!!

I wanted a product like this for adults as soon as I saw them being sold for kids! My teeth and gums were destroyed by orthodontics, I still have crowding even after years of braces and spending thousands on retainers. I’ve only been wearing this 6-8 hrs a night, but my teeth are...

Fantastic mouthguard

Really felt the difference over the past months, I sleep better and my facial structure started to align pretty quickly. Some funny effects as well is that I'm not anxious anymore, more social and not a people pleaser anymore! I switch between the R1 and R1.. the R1 is more comfortable to...

I'm only 2 months in

I'm only 2 months in, but so far so good. The first few nights it was really awkward because my mouth kept filling with saliva thinking I had food in my mouth. But then over time that has settled and I'm beginning to be able to wear it most of the way through the night. Way less jaw tension (...

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.
- The R2 large is the same width as the R1 large but is a bit longer. So if you were comfortable with the R1 large we recommend you get the R2 large size.
- The R2 medium is a bit larger than the R1 small and so is good for adults with a smaller sized mouth.
- The R2 does not currently come in a small size.
