Is Reviv worth it?
Doesn't add up (3.9/10). Reviv is a physical silicone appliance, essentially a bite guard, worn at night. As a mouthguard it is a plausible enough product category, but the sales page does not stop at protecting teeth from grinding. It builds a story where facial soft tissue is 'like a balloon' that teeth grinding deflates, which in turn 'crushes the skull' and 'crushes the brain,' causing cognitive decline, and claims the same device can reverse this and reshape the jaw, face and posture. No published research, dentist or craniofacial specialist is cited anywhere for any of this. The device itself may reduce grinding and clenching the way any night guard does, but the framing sells a facial-restructuring effect that has no clinical basis, from a company whose only named figure is a first name with no professional credentials shown.
What we liked
- Simple, one-time purchase with no subscription
- Material (food-grade silicone) is disclosed and is a reasonable choice for a mouth appliance
- Sizing guides are provided before purchase
- 60-day ClickBank return window applies like any ClickBank order
What we didn't
- Central marketing claim (tooth grinding "crushes the skull and brain") has no basis in craniofacial or neurological science
- No dentist, doctor or credentialed specialist named anywhere on the page
- Facial reshaping and posture claims are far beyond what a night guard can be expected to do
- Reviv One is explicitly stated to have no durability guarantee, unlike Reviv Two
- User and outcome numbers (8,000 users, testimonials) cannot be independently verified
What is Reviv?
Reviv is a food-grade silicone appliance you wear in your mouth while sleeping, sold in two versions. Reviv One is a firmer double-guard design available in Small or Large, described as having larger air holes and a medium level of contact with the gums. Reviv Two is a single softer guard available in Medium or Large, described as lower-irritation but with smaller air holes that the product's own comparison chart admits can make mouth breathing harder.
The sales page frames the product around what it calls a physics-based theory: that grinding your teeth down over time 'deflates' the soft tissue of the face the way letting air out of a balloon deflates it, which the page says in turn compresses the skull and brain and causes faster aging and cognitive decline. It claims wearing the appliance reverses this by adding height back to the bite, and links the concept to 'mewing,' an online trend around tongue posture and jaw shape, saying its own approach works faster and for more people.
Customer stories on the page describe changes in jaw angle, face width, posture and skin appearance over weeks of use. It is sold through ClickBank, which appears on the bank statement and manages returns.
Format: Silicone mouth appliance worn while sleeping, sold as Reviv One or Reviv Two. Sold by: Reviv (sold through ClickBank).
What is on the Reviv label?
Each row compares what the label or sales page states with what published research used. When an amount is missing, there is nothing to compare, and we say so.
There is no supplement label to assess here; the only material claim is '100% food-grade silicone,' which is plausible for a mouthguard and is stated clearly, unlike the health claims built around the device.
Do the Reviv claims hold up?
"Grinding down your teeth 'deflates' facial soft tissue like a balloon, which crushes the skull and brain, causing cognitive and neurological issues over time"
This is not an established mechanism in dental, orthodontic or neurological medicine. Adult skull bones are fused and do not compress from tooth wear, and no citation, study or named specialist supports this specific chain of claims anywhere on the page.
"In general we as a society like to call this process 'aging.' But if you grind down your teeth faster, you 'age' faster"
Tooth wear (attrition) is a real, well-documented dental phenomenon, but conflating it with generalized biological aging or cognitive decline is not supported by any reference on the page.
More effective and faster than 'mewing,' and should work for everyone
Mewing itself is a popular but scientifically unproven technique for reshaping the jaw through tongue posture. Claiming Reviv is faster and universally effective is an unverifiable comparison with no data behind it, resting entirely on the page author's stated opinion ('Ken's view').
About 8,000 people have used the appliance and method since early 2023
This is a bare number with no source, survey, or way to verify it, and it says nothing about outcomes or how many users saw any change.
How much does Reviv really cost?
| Option | Total | Per month | Shipping |
|---|---|---|---|
| Reviv One (Small or Large) | $100 | One-time | Not itemized on the order form (no separate line shown) |
| Reviv Two (Medium or Large) | $150 | One-time | Not itemized on the order form (no separate line shown) |
Reviv One is $100 in either Small or Large. Reviv Two is $150 in either Medium or Large. We ran both a Reviv One and a Reviv Two option through the live ClickBank checkout, and both matched the listed prices exactly ($100.00 and $150.00) with $0.00 tax and no visible shipping line.
This is a one-time purchase, not a subscription, and the product's own comparison graphic states Reviv One lasts 2 to 4 months before needing replacement, while Reviv Two is rated for 12-plus months. That makes the effective cost per year roughly $300 to $600 for Reviv One if replaced every few months, versus a single $150 purchase for Reviv Two.
There is no bundle discount for buying more than one unit, and no subscription or recurring charge appears anywhere on the order forms we tested.
Neither live ClickBank order form we tested (RevivOne Small $100, RevivTwo Medium $150) showed a separate shipping charge; both totals matched the sales page price exactly with $0.00 tax.
Can you get a refund on Reviv?
60-day window. The order runs through ClickBank, whose standard order-page guarantee allows a return or replacement within 60 days of purchase. Separately, the product page describes a 1-year durability guarantee on Reviv Two only, covering up to 2 free replacements if the appliance wears out; the page states Reviv One carries no such durability guarantee. These two guarantees are not the same thing: the 60-day window is for a refund, the 1-year offer is for a free replacement device.
Step by step: find the ClickBank receipt email, look up the order at clkbank.com and ask for a refund in writing. Our ClickBank refund guide covers returns, extra offers and auto-ship.
Which red flags did we find?
- Pseudoscientific mechanism as the central pitchThe "balloon theory" of the skull crushing the brain from tooth wear is the page's main selling point and has no support in craniofacial or neurological science.
- No dentist, doctor or researcher namedThe only figure referenced by name is "Ken," with no surname, credentials, license or institution given anywhere on the page.
- Facial reshaping claims from a night guardTestimonials describe jaw widening, face shape changes, posture correction and skin improvement from a mouth appliance, claims that would require orthodontic or orthognathic treatment to substantiate, not customer anecdotes.
- Two different guarantees easy to confuseA 60-day ClickBank refund and a separate 1-year, Reviv-Two-only replacement guarantee are both mentioned; the page's own comparison chart says Reviv One carries no guarantee at all.
- No user count or outcome verificationThe 8,000-user figure and testimonials cannot be independently checked.
Who should buy Reviv, and who should skip it?
It may suit you if
- You want a basic silicone night guard to reduce teeth grinding or clenching, and you ignore the jaw-reshaping and cognitive claims entirely.
- You are comfortable buying a device with no dentist involvement or custom fitting, relying on the sizing charts linked from the FAQ.
Skip it if
- You are looking for a scientifically supported way to reshape your jaw, widen your face or reverse cognitive decline; none of that is demonstrated here.
- You have a diagnosed bite, jaw joint (TMJ) or dental condition. A dentist-fitted night guard, not an unregulated one-size-approximation device, is the appropriate option.
- You want a company with a named, credentialed formulator or clinical advisor behind the product.

Reviv FAQ
Is Reviv legit or a scam?
It is a real silicone mouth appliance sold through ClickBank with a standard 60-day return window, so it is not a scam that takes your money for nothing. The concern is the marketing: it attributes cognitive decline and facial aging to tooth grinding through a mechanism with no support in dental or neurological science.
How much does Reviv cost?
Reviv One is $100 (Small or Large). Reviv Two is $150 (Medium or Large). Both are one-time purchases with no subscription, confirmed on a live ClickBank checkout for each.
Does Reviv actually reshape your jaw or face?
There is no published clinical evidence that a silicone night guard reshapes jaw structure, widens the face or improves posture. The claims on the page rest on customer testimonials and an unverified physics analogy, not dental or medical research.
How do I get a Reviv refund?
Because the order is processed by ClickBank, use your ClickBank receipt email or clkbank.com to request a refund within 60 days of purchase. This is separate from Reviv Two's 1-year replacement offer, which covers a worn-out device, not a refund.
Is Reviv safe to wear every night?
Food-grade silicone night guards are generally well tolerated, but anyone with an existing bite, jaw joint or dental issue should see a dentist before using an unfitted, non-custom appliance nightly, since a poor fit can worsen jaw problems.
