A violinist's year on the Reviv R3.
Mia is a violinist who spent years with poor sleep and an easily overwhelmed nervous system. A year on the Reviv R3, worn overnight, and she talks about a calmer system, a clearer head, and steadier coordination.

One year, in her own dated photos
Mia's own photos, timestamped from May 2025 to August 2026. An individual experience, not a typical result.
Same person, no filters, wearing the R3 overnight across the year.
The R3, the flat-plane guard behind her year
Worn while you sleep
Overnight, plus a few daytime hours if you want to move faster. No routine to learn.
Gentle, steady pressure
The flat-plane design supports the jaw without locking your bite, so it can settle where it should.
Ready out of the case
Premium soft silicone, food-grade tested. No boiling, no moulding. Backed by a 1-year warranty.
How did the R3 help Mia?
The three changes she talks about most. Her experience, not a promise.
A calmer nervous system
She used to tip into overwhelm easily, and struggled with sleep. Worn overnight, the R3 is part of what she credits for a steadier baseline. "It wouldn't take much to overwhelm me. Now I feel so clear."
A clearer head
The mental fog she lived with lifted over the months on the R3. "Mentally I didn't have any clarity at all. Now I'm so clear."
Coordination she can feel
As a violinist she lives on fine motor control and knowing where her body is in space. "I need coordination, I need proprioception, and now the message gets delivered properly."
Three steps. All of them easy.
Take it out of the box and wash it
Wear it to sleep and 2–3 hours during the day
Wash it and let it dry
Confused about size? Measure your width.
One measurement decides it: the width across your back molars.
Width · molar to molar
| Size | Width, molar to molar |
|---|---|
| Medium | 50 mm or less |
| Large | 51 to 56 mm |
| XL | 57 mm or more |
Tips: use a crisp, firm apple, make sure your teeth are clean and dry, press down evenly, and measure carefully in millimetres. No apple? Cut a piece of cardboard to the shape of your upper arch, or measure the width of a current retainer.
Consistency is the whole game
- Weeks 1-2: the adjustment phase. A little soreness or extra saliva is normal, your soft tissue is adapting, not a sign anything's wrong.
- Build up gradually: shorter daytime sessions first, then overnights. Ease off for a bit if it ever gets sharp.
- Over the months: the changes Mia talks about, a calmer system and a clearer head, came from wearing it consistently over a year, not from wearing it harder.
What people say about the R3
Questions, answered
How should I start? ›
Wearing it: the standard pattern is overnight plus 2 to 3 hours during the day. Build up gradually with shorter daytime intervals first. The early phase is the hardest and gets much easier after a few weeks.
Early discomfort: sore teeth, achy gums and extra saliva in the first weeks are the soft tissue adjusting, not a problem. Take breaks if it gets sharp, don't push through pain.
Faster results: consistency first, then simple stretches like Bite and Hold alongside the guard.
How does sizing work? ›
Width matters most. Measure the outer edges of your upper molars at their widest point, shown in this size guide video.
Medium (46mm) fits teens and smaller mouths, Large (53.6mm) fits most adults, and XL (59.6mm) is for larger mouths.
Why does it work? ›
Think of the soft tissue over the skull like a balloon. Grinding your teeth down deflates it over time, what we tend to call "aging." Adding height back with gentle, consistent pressure runs the same physics in reverse.
How many people have done this? ›
Over 30,000 people have started using Reviv appliances and this method.
What is it made of, and what's included? ›
