If you’re serious about looksmaxxing, you probably already obsess over sleep, posture and tiny daily habits that add up. I tried the Reviv mouthguard for several months and — spoiler — it’s one of the few tools that actually feels designed for aesthetic progress, not just protection. This review is my user take: what it does, how it works, who it’s for and what to expect if you decide to add Reviv to your nightly routine.

What is Reviv?
Reviv is a soft, formable mouthguard made from 100% food-grade silicone, built specifically to support jaw alignment, reduce nighttime clenching/grinding and keep the lower face in an “aesthetic rest state” while you sleep. Unlike standard sports or boil-and-bite guards, Reviv is pitched as a looksmaxxing tool — a night appliance that helps your facial structure retain and (reportedly) enhance the gains from daytime practices like mewing and posture work.
The company positions Reviv as more than protection: it’s a nightly alignment device intended to lock in progress and prevent the overnight “reset” that can happen due to clenching and poor bite position.

How Reviv Works (The idea behind it)
Reviv’s designers point to the “Curve of Spee” — a subtle natural curvature of the lower teeth — as a key alignment marker. The claim: daytime practices (tongue posture, mewing) help reposition the bite and soft tissues, but at night, clenching and gravity can erase those gains. Reviv aims to maintain a supportive jaw posture overnight so improvements can compound rather than regress.
Mechanically, Reviv:
- Provides a stable, neuromuscular-friendly position for the jaw.
- Reduces grinding/clenching by creating a comfortable, evenly distributed contact point.
- Keeps lower-face musculature in an aesthetic, relaxed position that may support symmetry and lower-face slimness over time.
I’ll be clear: these are functional, structural claims and individual results vary. The explanations in the product material are framed as why users see aesthetic improvements — and many early adopters report positive changes. In this review I’ll cover what I personally noticed, plus what to reasonably expect.
Key Features at a Glance
- Material: 100% food-grade silicone (BPA-free).
- Fit: Moldable—boil-and-bite style for a snug, personalized fit.
- Design goal: Support jaw alignment and reduce clenching while sleeping.
- Comfort: Low-profile, described by many as “barely noticeable” once molded.
- Target audience: People experimenting with looksmaxxing, mewing or anyone who clenches/grinds at night and wants a cosmetic and comfort-focused appliance.
- Claimed traction: The maker reports thousands of users since early 2023 and offers a satisfaction guarantee.
My Experience — Nightly Use & Comfort
I wore Reviv every night for several weeks to get a real feel for it. The first two nights felt strange — any foreign object in your mouth takes time. The big win: after molding the guard properly, it became comfortably snug and didn’t interfere with my breathing or sleep. I could sleep on my back and sides without waking up to jaw soreness, which was a major change from the occasional morning stiffness I used to get.
A few practical notes from personal use:
- Molding matters. Taking the time to fit Reviv properly makes all the difference. The first fit was okay; after a second remold I noticed dramatically better comfort.
- No weird gag reflex. The low profile makes it less intrusive than bulky sports guards.
- No speech during use. Obviously you don’t speak while sleeping, but in case you try it awake for a minute to test comfort: pronunciation is slightly affected but tolerable.
- Care & cleaning. Rinse and let air-dry. The silicone wiped clean easily and showed no odors after weeks of use.
What Results Can You Expect?
Everyone’s face is unique, so expectations should be realistic. Based on my experience and the frequent reports within the community, here’s a reasonable timeline:
- First 1–4 weeks: Better sleep comfort for grinders, fewer headaches from clenching, morning jaw soreness reduction.
- 1–3 months: Subtle improvements in lower-face tone and perceived slimness, improved facial rest posture while awake.
- 3–6 months+: If you combine Reviv with daytime posture training or mewing, many users report more noticeable jawline definition and improved facial symmetry as soft tissues adapt.
Remember: Reviv is a supportive device. It won’t replace orthodontic treatment when that’s needed, but it can be a helpful tool in a non-surgical aesthetic routine.
Who Should Buy Reviv?
Reviv is especially well-suited for:
- People already practicing mewing or tongue/posture training who want to prevent overnight regression.
- Nighttime grinders and clenchers who want a comfortable, non-bulky guard.
- Looksmaxxing enthusiasts aiming for non-invasive, cumulative facial improvements.
- Anyone who wants to experiment with jaw-support appliances before pursuing more invasive interventions.
If you have major dental or TMJ issues, consult a clinician first. Reviv is not a substitute for professional dental treatment.
Comfort, Safety & Build Quality
Reviv’s food-grade silicone construction feels durable and soft. The material is BPA-free and designed for nightly contact. After molding, the guard is snug and minimally intrusive, which is essential for consistent use — if a device is uncomfortable, you won’t keep wearing it and won’t see results.
The company’s messaging emphasizes neuromuscular support over forceful repositioning — the goal is to guide your jaw into a stable, relaxed posture rather than aggressively shift bone structure. For aesthetic aims, a comfortable, repeatable nightly habit is what counts, and Reviv hits that mark for most users.
How to Use Reviv — Quick Start
- Boil & Mold: Follow the included instructions to soften the silicone and mold the guard to your teeth for a personalized fit.
- Test-fit: Wear it for a few minutes awake to check comfort and breathing.
- Sleep with it nightly: Aim for consistent use to get the compounding effect the makers describe.
- Clean regularly: Rinse after use and let it air-dry; deep-clean weekly as instructed.
Consistency is the secret sauce here — the device is built to lock in progress over time, so using it most nights will deliver the best aesthetic results.

FAQ
Is Reviv the same as mewing?
No — mewing is an active daytime posture technique. Reviv is complementary: it helps keep your jaw in an aesthetic rest position overnight so the daytime gains are not undone by clenching or poor bite position.
Is it comfortable to sleep with?
Most users (myself included) find Reviv comfortable after a proper mold. It’s considerably less bulky than a sports guard.
What is it made from?
100% food-grade silicone, BPA-free.
How quickly will I see results?
You may notice reduced clenching and better morning comfort within weeks; facial changes like improved lower-face slimness typically emerge over months when combined with consistent daytime practices.
How many people use it?
The maker reports thousands of users since early 2023. That’s a solid early-adopter base for a specialized aesthetic appliance.
Final Verdict — Is Reviv Worth It?
If you’re pursuing non-surgical ways to enhance your jawline and facial balance, Reviv is one of the more thoughtful nighttime tools out there. It’s comfortable, well-made and designed specifically to be compatible with mewing and posture work. For me, the combination of better sleep comfort, reduced morning jaw soreness and a gradual improvement in lower-face tone made it a product I’d happily recommend to fellow looksmaxxing enthusiasts.
Will it transform your face overnight? No. But if you treat it as part of a longer-term routine — daily posture/mewing practice plus nightly Reviv use — the compound effect is real for many people.
If you’re intrigued, consider trying Reviv for a few months and see if it helps lock in your daytime progress. For anyone committed to cosmetic, non-invasive gains, it’s an easy, low-friction experiment that can deliver noticeable long-term benefits.
