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 am liking it so far

I am liking it so far. It is actually quite a wild experience. I am really really really appreciating the support group and would recommend that to anyone who makes a purchase. Using the Reviv is quite a phenomenal experience and the guidance and support for the process is invaluable imo.

I’m very grateful for this

its been fantastic

Headaches

I have had a total of about 3 headaches in my entire life. For myself, I consider myself extremely fortunate, I rarely rarely ever have headaches. Upon using this product, I started to have 2-3 headaches for 15+ minutes, daily. When I ceased using the product, the headaches dropped to about once daily within 2 days and by a week I was down to 1 every 3 days and within ~3 weeks, they were gone entirely.

I gave a second round a shot, again, headaches immediately started which is incredibly atypical for me and persisted for my entire week trial. Again, stopping took about 3 weeks for the headaches to subside. Whatever this does to my "jaw" or "fascia" doesn't seem healthy to my as feeling in intense headache pain doesn't seem "healthy" but rather a sign of bad health or you are doing something wrong... ex not drinking enough water, not enough sleep, using weird mouth contraptions?

I didn't see any noticeable improvement in my jawline or jaw muscles either week of trial -- but probably too early. When I went on their 'sckool' group/community I found others complaining of headaches too so I guess I am not alone. But also found many people who didn't get headaches. So...not really sure, tbh.

I very clearly tell folks for a long time that headaches are a part of the process and i consider them a good thing https://reviv.substack.com/p/headaches-are-part-of-the-process

A couple years ago i had at least 1 headache a day... but my head, concentration and cognitive function all improved a lot.

A girl in my first test group in 2024 had brain fog and had headaches daily for 3-4 months but got out of her brain fog.

I guess at the end of the day when you do this process some level of 'trust the process' is needed.

How are these people that complained of headaches on skool doing now? I have a feeling most of them, if they're doing this for at least a couple of months, will list out various things that they feel they have improved.

Great product

I had the Reviv 1 before this, and it was good. This one is better. I wear it every night and I can tell it's helping.

Held in reserve

My review is for R1 which I am still using. Ordered R2 for when R1 completes its mission. Don't want a gap in use.

It's a good fit finally

It's a good fit finally. Thanks for your customer support!

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.
