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."

Definitely and improvement over the R1

Definitely improved over the R1.
As someone who has and uses a Functional Activator (R2 was for my girlfriend), I’d like to see the next generation remove the air holes entirely, and use a slightly harder material.

More robust

Reviv2 is a heftier version of the original - seems to be working more comprehensively than Reviv 1.0 - definitely feeling the expansion of the face, and the upper and lower teeth are meeting more usefully.

Miracle for my back pain and pelvic tension

Miracle for my back pain and pelvic tension. It's a slow progression. And painful for me, but I see huge improvements and can't wait to see more.

Awesome product that gets rid of so many problems

Awesome product that gets rid of so many problems.

I couldn’t wear it

I couldn’t wear it. Experienced mouth breathing waking with dry mouth. Very unpleasant.

Rebecca, we sent you 2 appliances that you never paid for in November, which it turns out later you happily wore.

We just then refunded you everything except for $15 for shipping for the R2 that you ordered because u said it was uncomfortable. However we tell everyone upfront that this process is often uncomfortable.

I've answered the probably 20+ questions you've left on our substack.

And we are rewarded for all of this effort with your 1-star review.

I'm sorry but please stop bothering me at this point.. as I do not plan to answer any more of your questions.

There needs to be balance. And this is not balance.

Better than Starecta

I'm quite familiar with meme appliances like Starecta and conduct a bit of biomechanical study (mostly PRI) to address my asymmetries. RevivTwo is a great little appliance that has been giving me very steady gains.

It's not going to change you if you don't know what your goals should be, that is a more symmetrical, healthier, biomechanically sturdier body. You can for sure use this device wrong by locking into a bite that's comfortable yet chronically damaging to you -- your old bite essentially.

So it has already begun straightening my front 2 teeth. It has also shifted my lower jaw more to the right, although I'm less symmetrical when aligning teeth, overall I'm more symmetrical everywhere else. Have been wearing it anywhere between 4 to 12 hours a day, every day.

Doesn't smell as bad as the Starecta with regular use. Well constructed. Pretty comfortable when you get used to it. It doesn't have weird manufacturing edges and defects that irritate the mouth.

HOW 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

Frequently Asked Questions

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 5,000 people have started using the appliance and this method since early 2023.

How does sizing work?

Note that there is a 'Size chart' above that you should refer to for measurements of our appliances.

For R1:
- 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.

For R2:
- 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.

How are R1 and R2 different?

Here is our view:
- Material: R2 is made of liquid silicone which is stronger and far more durable than the R1. This makes R2 a better appliance for folks that clench and grind.
- How long it lasts: R1 will probably last 3-4 months before it deforms whereas we believe R2 will last at least a year.
- Guarantee: R1 has no guarantee. R2 is guaranteed for one year with a max of two free replacements.
- Design: R2 is a bit easier on the gums as it doesnt ride as high up on the gums as R1
- Price: R1 ($25) vs. R2 ($80), however

What is the appliance made out of?

It is made out of 100% food grade silicone.
