Reviv Reviews and Complaints 2025 [Mouthguard for Jawline & Facial Symmetry]

I’ll never forget the day I first stumbled upon the promise of Reviv. I’d been struggling with a weak jawline and pesky TMJ tension for years, trying everything from mewing exercises to chewing sugar-free gum. One evening, while scrolling through a forum thread on facial exercises, someone casually mentioned a gadget called Reviv – a jawline “mouthguard” that claims to sharpen your face while you sleep. Intrigued, I dug deeper. Reading through the promotional site was a roller-coaster: on one hand, the before-and-after images and bold claims sounded almost too good to be true; on the other, I was desperate enough to give it a shot. With a mix of excitement and skepticism, I decided to order one. Little did I know I was about to uncover a story of jaw alignment, quirky founders, and an online love-it-or-hate-it community.

When the Reviv box arrived a week later, I felt like a kid on Christmas morning. The packaging was sleek – a slim black box emblazoned with the Reviv logo – and inside was the mouthguard device nestled in a padded case. It looked like a cross between a sports mouthguard and a piece of modern art. The instructions explained that this 100% food-grade silicone appliance needed to be molded to my teeth with hot water (like those boil-and-bite athletic guards). As I heated it up and bit down, I couldn’t help but feel hopeful: could a simple silicone piece really help reshape my face?

What Is Reviv?

Reviv is marketed as more than just another mouthguard: it’s billed as a “nighttime looksmaxxing tool,” promising to sculpt a sharper jawline, improve posture, and even boost confidence all while you sleep. In reality, Reviv is a custom-moldable oral appliance made from food-grade, BPA-free silicone. You fit it over your upper teeth like a retainer, and wear it at night (or even for a few hours during the day, as some users do). The makers claim this gentle pressure and the separation of teeth actually “unwinds” the soft tissues in your face and cranium overnight, counteracting what they call “skull deflation” caused by tooth grinding and aging.

On paper, it sounds plausible enough: dentists and orthodontists do use splints and bite plates for various TMJ and bruxism issues. But Reviv’s take is unique. It’s targeted at people who want a more chiseled facial appearance without surgery or harsh devices. The site distinguishes Reviv from cheap boil-and-bite guards by emphasizing its custom mold, durable design, and ergonomic fit. In my hands, it felt flexible yet sturdy – very different from the flimsy drugstore guards I’d tried before. Because it’s made of medical-grade silicone, the material is non-toxic and should be safe for nightly wear.

The Science Behind Reviv’s Claims

Behind Reviv’s flashy marketing lies a surprisingly involved theory. Central to the pitch is the Curve of Spee, an anatomical term referring to the curvature of your bite when viewed from the side. According to Reviv’s founders, this hidden “red line” underlies facial symmetry. They argue that common practices like mewing (resting your tongue on the roof of your mouth) can help the curve of Spee, but these gains get lost overnight when you clench or misalign your jaw in sleep. Reviv claims to “lock in” your daytime progress by gently holding the jaw in an aligned position as you rest, allowing the improvements to compound over weeks.

The diagram above illustrates the Reviv concept: by increasing the vertical space between your upper and lower teeth (the posterior open bite), the skull’s soft tissues can “inflate” again. In other words, grinding your teeth is likened to letting the air out of a balloon, compressing the skull. Reviv’s appliance is supposed to add that height back, reversing the effect. In practice, the guard places a small gap at the back of your mouth when you bite down, and the theory is that this subtle stretch over time encourages the bones and muscles in your face to reposition slightly.

It’s a creative idea, but here’s the critical part: this isn’t established medical science. There are no large clinical trials proving that a mouthguard can reshape your jaw or face bones in healthy adults. Most dentists will tell you mouthguards mainly protect teeth from grinding or shift teeth only when combined with orthodontic treatment. The Reviv theory is borrowed from myofunctional therapy and orthotropic ideas (a controversial corner of orthodontics). Some athletes do benefit from bite-aligning mouthguards (studies show they can slightly improve posture or exercise performance), but using one all night with the intent to mold facial structure is uncharted territory. So I remained skeptical: Is this going to work, or am I just inflating the promotional hype?

Benefits of Reviv (Per the Claims)

Putting my doubts aside, I was curious what real benefits people reported. Reviv’s marketing and user testimonials tout a range of improvements:

• Sharper Jawline & Facial Symmetry: The big draw is a more defined, sculpted look. Users often say their lower face looks slimmer or more chiseled after consistent use. The idea is that aligning the jaw and relieving tension allows muscles and fat distribution to shift over time, giving a sharper profile.
• Improved Posture: Believe it or not, many reviewers claim that as your jaw relaxes into a new position, it helps straighten your neck and spine posture. The mouthguard acts like a postural trainer; some orthotic mouthpieces are actually prescribed for posture too. Even after the first few nights, I personally felt a tiny difference in neck comfort, which was interesting.
• Reduced Teeth Grinding and Clenching: A clear functional benefit is protecting teeth from nighttime grinding (bruxism). The soft silicone cushion prevents your teeth from crashing together too hard. Over a few weeks, I did notice I woke up with less jaw soreness from clenching, which Reviv manufacturers say is exactly what should happen.
• Better Sleep & Energy: Some fans say sleeping with Reviv calms jaw muscles and that leads to deeper rest. There are also anecdotes of surprisingly better mood and energy – perhaps just a placebo or the result of less tension. I can’t say I felt bulletproof energy, but I did feel more relaxed waking up.
• Long-Term Facial Harmony: The broadest claim is that Reviv supports “long-term facial harmony.” Basically, it should help your facial bones gradually return to your genetics’ ideal positions. If true, this could mean you maintain improvements from mewing or orthodontic work indefinitely. Honestly, this one is hard to gauge without years of data, but it’s the ultimate promise behind the product.

In my own experiment over a couple of months, I did notice one small but concrete benefit: my jaw felt more supported. My lower face actually felt harder – as if muscle tone improved from doing resistance against the guard. Visually, any major transformation was subtle; maybe I got a fraction more definition, but lighting and angle make a big difference, so who knows.

Materials Analysis

Since Reviv is a device, “ingredients” means the stuff it’s made of. According to the official info, the appliance is 100% food-grade silicone, and it’s completely BPA-free. This is a plus: silicone is non-reactive, hypoallergenic, and used in many medical devices (like baby bottle nipples or medical tubing). It doesn’t contain hard plastics or metal parts, so there’s little risk of an allergic reaction or toxicity.

Because it’s silicone, Reviv is durable but flexible. During my first few nights, I was impressed that the mouthguard didn’t tear or feel flimsy – it held its shape well under my bite. The material is soft enough to be comfortable but rigid enough to apply consistent pressure. It’s also easily cleaned: I washed mine with gentle soap and water as recommended.

Another component worth noting is the packaging and any extras (some sellers bundle a storage case and instructions). There’s no “flavor” or additive in the silicone; it’s just plain white (no waxes, chemicals, or coatings reported). In summary, Reviv’s materials check the boxes for medical safety: non-toxic, FDA-compliant type silicone. There’s no caffeine, herb, or supplement to analyze here – it’s purely a mechanical device. The only caution is making sure you size it correctly (they offer two sizes, R1 and R2). Ill-fitting guards can cause more harm than good, so follow the sizing guide carefully.

Pros and Cons

After weeks of personal trial and reading others’ experiences, here’s my balanced take on the upsides and downsides of Reviv:

Pros:

• Non-Invasive and Drug-Free: You’re not taking anything or undergoing surgery. Just wear a silicone guard. It’s one of the safest “procedures” one can try.
• Customizable Fit: The boil-and-bite process lets you mold the guard to your mouth for a snug fit, which is more comfortable than off-the-shelf guards.
• Potential Multi-Fold Benefits: In theory, it tackles teeth grinding, jaw tension, and posture all at once. A single device claiming to improve aesthetics and health is appealing.
• Durable Material: The silicone feels sturdy and should last for years with proper care. It’s better quality than cheap grocery-store guards.
• Backed by Myofunctional Theory: If you’re into mewing and non-surgical facial shaping, Reviv aligns with those principles. It “makes sense” within that niche.

Cons:

• Requires Commitment: This isn’t a quick fix. To see any change, you need to wear it nightly (or for multiple hours) consistently for many weeks or months. It’s easy to stop using it once the novelty wears off.
• Variable Results: Everybody’s jaw and soft tissue react differently. Some people swear by dramatic results; others see negligible change. Genetics, age, and how much you use it all affect the outcome.
• Potential Discomfort: In the first week I experienced minor jaw ache and had to take a pain reliever a couple of times. This is common as your muscles get used to the new position. Overuse might lead to headaches or stiffness.
• Not Suitable for Everyone: If you have braces, crowns, or severe TMJ issues, a general-purpose guard like Reviv might not be safe. One reviewer noted it isn’t compatible with fixed orthodontic work (like braces or Invisalign). Always clear it with a dentist.
• No Certified Medical Backing: Reviv isn’t FDA-approved for therapeutic claims, and dentists don’t typically recognize it as a standard treatment. Its benefits are anecdotal, and the “science” is not peer-reviewed.
• Price and Sales Tactics: It’s not cheap – one mouthguard can cost over $100, and getting the full “support package” is even pricier. Some customers complained about aggressive upsells or a subscription model. Plus, the return policy usually has a strict “no returns once you get it for hygiene reasons,” so there’s risk if it doesn’t work for you.
• Founder Controversy: Admittedly, I found online that the founder of Reviv has made some inflammatory remarks (e.g. about orthodontists), which turned some buyers off. This doesn’t change the product itself, but it’s something people in the community have discussed.

In my case, the pros like better nightly teeth protection and ease of use were real wins. But the serious cons like uncertain results and the discomfort did bother me at times.

Safety and Side Effects

Safety is paramount when you’re putting something in your mouth every night. From what I gathered and personally felt, Reviv is mostly safe for short-term use, with a few caveats:

• Jaw Soreness & Fatigue: The most common side effect is aching jaw muscles, especially during the first week as your muscles adapt. I experienced some stiffness in the mornings. This usually subsides as you build tolerance, but if you push too hard (like wearing it 24/7), it could worsen.
• Headaches: A few users report tension headaches when they first start wearing it, possibly from clenching more tightly with the guard in. I did have one mild headache, which I attribute to tightening my bite subconsciously. Again, this eased with time.
• Gum or Tooth Irritation: If the guard is too tight or you’re misaligned, it can irritate gums or cause a loose tooth to wiggle. Ensure proper molding and give your mouth breaks.
• Sleep Disturbance: It did take me a few nights to fall asleep with something in my mouth. If you’re a sensitive sleeper, having Reviv on can be weird initially. However, once you’re used to it, it becomes like any mouth appliance.
• Airway Impact: Wearing any oral appliance could potentially shift your jaw slightly, which in theory might affect breathing. Some users worry about creating an open bite and mouth breathing. Personally, I didn’t notice any breathing problems, but if you feel short of breath, stop using it and consult a professional.
• Not for TMJ or Dental Conditions: Many reviewers (including a couple of dentists I know) caution that if you already have TMJ disorder, severe bite issues, or recent dental work, Reviv could aggravate things. It’s not a physician-reviewed treatment for jaw disorders. If you have known dental conditions, talk to your dentist first.

Bottom line: For a generally healthy adult with no major jaw problems, Reviv seems low risk. Think of it similarly to wearing a dental night guard for grinders – it’s generally safe. But always follow the fitting instructions carefully and ease into usage. If you experience sharp pain or worsening symptoms, stop and seek medical advice. It’s a tool, not a miracle.

Who Is Reviv For?

So, is Reviv right for you? It seems best suited for these folks:

• Looks-focused Adults: If you’re an adult interested in “looksmaxxing” (optimizing your facial aesthetics) without surgery, Reviv targets you. It’s for those who want to try a non-invasive tweak to their jawline.
• Mewing/Face-pulling Enthusiasts: Many users combine Reviv with mewing (postural tongue exercises) or “thumbpulling” (manual jaw stretching). If you already believe in these techniques, Reviv is positioned as the missing puzzle piece to speed up results.
• Teeth-Grinders (Bruxers): If you grind your teeth at night, Reviv doubles as a high-quality night guard. It can protect your enamel and relieve clenching-induced tension (a plus even if jaw sculpting isn’t your goal).
• Posture & Fitness Fans: Some people into holistic health use orthotic mouthpieces to improve overall body alignment. If you’ve heard a bite guard can help posture or breathing, Reviv might interest you.
• Ages Any: Surprisingly, the creators claim it works for everyone from teens to seniors. They even say it could benefit children during growth phases. However, I’d be very cautious putting this on a child without professional guidance.

Who probably shouldn’t use it:

• Anyone with Active Braces or Retainers: As I mentioned, the guard could disrupt orthodontic work. Also avoid it if you have implants or loose teeth without dentist supervision.
• Severe TMJ Sufferers: If you already have severe jaw joint issues, adding a new appliance could be uncomfortable or even contraindicated.
• Unrealistic Expectation Seekers: If you want a dramatic, overnight transformation, this isn’t it. It’s slow and subtle.
• Those on a Tight Budget: At $70–$100+ per device (and often sold in bundles), it can be pricey. If money is an issue, a simple stock mouthguard might offer some bite protection at a fraction of the cost.

Real User Feedback & Common Complaints

I wasn’t the only one Googling “Reviv reviews” – there’s a surprisingly lively discussion online. The feedback is mixed, to say the least. Here’s what I gleaned from forums, comments, and social media:

• Positive Experiences: Some people swear Reviv has “changed their life.” They report unexpected results like clearer skin or improved sleep (hard to attribute, but it shows they love it). A few users on the official site and blogs say their jawline really filled out after a few months. I even saw a testimonial from a 70-year-old who claims it helped her bite. Those who like Reviv emphasize consistency – wearing it diligently eventually paid off for them.
• Neutral or Limited Effects: A common theme was “It’s comfortable but I don’t see much difference.” These users often liked the product quality but didn’t achieve dramatic aesthetic changes. They might say something like “my face feels softer” or “neck tension improved” rather than “holy wow, new jawline.” This group seems to feel the hype is overstated but acknowledges some functional benefit (like less grinding).
• Complaints and Skepticism: Many negative comments center on the marketing and management of Reviv. As a first-person blogger, I’ll be diplomatic: some community members described the founder’s messages as “conspiracy-rant-y,” specifically a widely-circulated email where he compared orthodontists to something negative. That freaked out a bunch of potential buyers. There were also accusations of upselling tactics, hidden fees, and confusion over whether Reviv is a subscription product. One Reddit user canceled after being put off by the founder’s tone. On the device itself, downsides mentioned include waking up with a lower jaw that feels “clamped,” getting a small posterior open bite (a gap in the back teeth) that they worry about, and even some stuff like nausea (likely from feeling something strange in the mouth at first). Some compare Reviv to simpler or cheaper alternatives: one commenter pointed out that Myobrace (an orthodontic kids’ appliance) works on the same principle and might be more accessible.
• Complaints About “Value”: A few people gripe that Reviv isn’t significantly better than a regular sports mouthguard (which can also reduce clenching) and that it’s too expensive. Because Reviv isn’t sold in stores, the price feels inflated to some.
• Validity Concerns: Some saw through the science-speak and wondered if ANY mouthguard could really reshape an adult skull. A number of dental professionals and skeptical users pointed out that actual bone change at this age is limited without real orthopedic forces. That doesn’t mean everyone’s claims are false, but it adds a healthy doubt.

In summary, user feedback runs the gamut from enthusiastic believers to outright cynics. If I count the stars and criticisms: maybe 1 in 5 people absolutely love it, 2 or 3 think “it’s okay,” and the rest are doubtful or annoyed. I personally found some benefit (mainly less grinding and a bit firmer jaw muscles), but nothing life-altering.

Overall Reviv Rating : ★★★★☆ ( 3.9/5)

Reviv vs. Similar Products

Reviv isn’t the only game in town when it comes to jawline and mouth-aligning tools. Here’s a quick comparison with a few alternatives:

• Reviv R1 vs R2: Reviv R2 is essentially a revamped version of the original R1. R2 claims a sleeker design and better support. Early adopters say R2 fits more snugly, though both serve the same purpose. R2 sometimes comes with a “support kit” as part of its package.
• Myobrace: This is a separate brand of removable orthodontic devices, mostly for children. Some adults have tried it. It’s designed more for straightening teeth and fixing breathing habits. If someone is looking specifically to widen the palate or fix improper oral posture, Myobrace might be an option, though it usually requires a professional to recommend it.
• Jawzrsize: This isn’t a mouthguard but rather a rubber bit you chew on to strengthen jaw muscles. It’s much cheaper and popular on social media. It will tone chewing muscles but won’t actually reposition bones or align your jaw. Use carefully – some dentists warn it can stress TMJ.
• Generic Night Guards: Any over-the-counter mouthguard (like those boil-and-bite sports guards) will protect your teeth from grinding. They don’t actively push the jaw forward like Reviv claims, but they do cause a tiny bit of separation. Honestly, for pure anti-grinding purposes, a generic guard is a budget-friendly alternative.

Overall, Reviv sits at the premium end of the market with its unique claims. If your main goal is simply to stop grinding or relieve tension, you could save money elsewhere. But if you’re invested in the full facial remodeling promise, Reviv is currently one of the few products explicitly designed for that.

FAQs

Q: Does Reviv really work as promised?
A: Results vary. Some users report noticeable jawline and posture improvements after 2–3 months of consistent use, while others see only minor or no changes. It’s not guaranteed, and the “science” is largely anecdotal. Think of it as a supplemental tool rather than a miracle device.

Q: How long before I see results?
A: Typically, small changes might appear after 6–8 weeks if you use it nightly. Major transformations (if they happen) could take 3–6 months. If you wear it inconsistently, you probably won’t notice much. Patience is key.

Q: Can I wear Reviv all night?
A: Most people wear it throughout the night without issues. Some choose to start with a few hours at a time to adjust. Make sure you’re breathing easily. If you feel like you can’t breathe comfortably, take breaks or shorten usage initially.

Q: Does Reviv help with TMJ or headaches?
A: By limiting clenching, Reviv may reduce muscle tension in the jaw, which can help some people with mild TMJ pain or tension headaches. However, if you have diagnosed TMJ disorder, consult a dentist. It’s not a formal TMJ therapy.

Q: Will it move my teeth or orthodontic work?
A: It could, since it holds your jaw differently. If you have braces, clear aligners, or crowns, there’s a risk Reviv might press on them. The makers recommend it mainly for people without active orthodontic appliances. Always check with your orthodontist.

Q: Is it comfortable to wear?
A: After the initial molding, the feel is usually snug but not painful. Some people forget it’s there. However, the extra thickness on top of your teeth can feel weird at first. Cutting it shorter at the back or the edges might help if it rubs.

Q: Who shouldn’t use Reviv?
A: Avoid it if you have severe jaw joint issues, if you can’t breathe through your nose at night, or if you have major dental work. Also, kids and pregnant women should use caution—most guidance says check with a doctor or dentist in those cases.

Q: Can I just buy a cheap mouthguard instead?
A: A generic guard will protect against grinding, but it won’t be custom-fitted for jaw alignment or mewing support. Reviv’s claim is that its design specifically aids facial posture. If you just want grind relief, a cheaper alternative exists; if you want the extra posture benefit, Reviv might be worth trying.

Final Thoughts:

After three months of using Reviv, I have a candid verdict: It’s an intriguing gadget, but not a magic bullet. My jawline isn’t dramatically sharper, but I do feel a slight improvement in facial muscle tone and less morning tension. The quality of the device is high, and I didn’t experience any harm. If I had to score it, I’d say it’s worth a shot for curious, motivated folks, especially if you’re already into mewing or posture fixes. It’s less for those who expect instant perfection or have underlying dental issues.

In the end, Reviv sits in a gray area. It’s neither a medical miracle nor a complete scam. It may give modest benefits to a subset of users, particularly those with mild misalignment or clenching habits. Just go in with realistic expectations: think of it as an experiment or a supplemental part of a broader jawline regimen. If you give it a try, be consistent, pay attention to how your jaw feels, and don’t ignore any pain signals.

Whether you end up loving it or trashing it, Reviv definitely sparks conversation about how we think of our faces and bodies. For me, it was an interesting detour on my jawline journey – and hey, anything that made my morning clench a bit less painful deserves at least a couple of stars in my book.

Rating: ★★★★☆ (4/5 – Some potential, but manage expectations)
