How Zerene Works in 3 Steps

Diagram showing person lying in bed using Zerene with data capture mode on a purple background.

Step 1

Study (Nights 1–5)

Wear Zerene for a few nights without any feedback turned on. The app maps your clenching: when it happens, how hard, and how often.

Step 2

Train (Nights 6+)

The moment you start clenching, Zerene sends a whisper-quiet vibration. It interrupts the grinding and you learn to relax without waking up.

Step 3

Maintain (As Needed)

Once you learn to stop grinding, you won't need to wear Zerene every night. Use it when stress spikes or as a check-in.

Frequently Asked Questions (FAQs)

A cheap mouthguard protects your teeth tonight. It won't change anything about what your jaw does tomorrow, or the night after. Zerene is a training program — more like a fitness plan than a product. Most users find that reduced bruxism, lower pain, peace of mind, and better sleep are all far more valuable than the cost.

Both, but the primary goal is retraining. Zerene's custom mouthguard provides dental protection from night one. The Moon Module works in parallel to retrain the neuromuscular pattern that causes grinding in the first place. Most users find that protection becomes less necessary over time as the training takes effect.

Most users stop noticing the Moon Module within a few nights. At about 10 grams, roughly the weight of two nickels, it's designed to stay out of your way while you sleep. The mouthguard is custom-made from your own dental impressions, so it fits precisely, and the soft, flexible material makes it more comfortable than the rigid guards most people have tried before. If you're sensitive to anything in your mouth at night, the thin profile makes a real difference.

Many users start seeing a difference in their grinding within 2 weeks of training. Some notice fewer headaches and less jaw soreness in the first week. Results vary, but you'll have data to track your progress from night one.

Yes. Zerene is designed for side and back sleepers. The mouthguard is built to ensure the device stays secure no matter your sleep position.

Yes. Zerene is HSA and FSA eligible, which means you can use pre-tax dollars toward your purchase. Check with your plan administrator to confirm eligibility under your specific account.

Your $349.99 purchase includes 90 days of full Zerene access: data tracking, coaching support, and the complete training program. After that, a subscription of $29.99 every 6 months keeps your app, your Z-Score data, and your coaching team active.

You're covered by a 100% money-back guarantee (see Terms for details). If Zerene isn't the right fit, you won't be out of pocket. Your coaching team will work with you first, but if it's not working, we'll make it right.

As a physiotherapist working in a university Orofacial Pain/TMD clinic. I was intrigued about ZERENE. We use appliances and teach strategies to help minimize muscular and joint strain/pain but ZERENE offers an opportunity to diminish the strains and actions from nocturnal bruxism.
It was fairly simple to order and with the on-line instructions and the immediate response from the team at ZERENE, the Study and Training phases ran smoothly. To be able to see my scores improve dramatically was a pleasant surprise. COACH ZERENE was then able to assist in the next phases of breaks to see how the training helped and when I should restart the Study/Training cycle. I have been pleased with the support and increased time between cycles.
I also have used CPAP for 40+years. I currently use nasal pillows and the ZERENE module works well in combination with my setup. In fact, the headgear setup actually protects the straw/module during my changes in position throughout the night.
ZERENE has performed as it stated and I have been able to confidently recommend ZERENE to individuals that are having continued concerns after traditional oral appliances and treatments.
Thank you to the ZERENE team.

This thing has been life changing. I've been grinding my teeth - HARD - for 30+ years. Headaches, jaw pain, broken teeth, inflamed gums - I've got it all. When I saw an ad for Zerene, I was intrigued, but honestly a little put off by the idea of having something sticking out of my mouth all night. I thought about it for quite a while, but finally decided to give it a go, and....wow. Just WOW. It took me exactly one night to be completely accustomed to the tube. The readout for that first night was sobering - yeah, I grind hard. And I grind all. Night. Long. Rather, I should say, I USED TO grind hard all night long. As I write this, I've worn the Zerene right around 50 nights, and the improvement is almost too good to believe! Not only do I grind less; I grind more gently. And I'm just getting started! The customer service has been incredible too - my coach is super responsive and helpful. The one time I had a problem, she responded right away with an easy fix. If you're still on the fence like I was, trust me: it's worth it. If I'd had this thing years ago, I would have saved many thousands of dollars in dental work.

I've been using Zerene for about a month now and am thrilled with my results. My bruxism has improved by 93% and I can open my mouth wider than I've been able to in over 20 years! The coaches are truly excellent and are helping me build a plan to stop using a mouthguard completely, something I honestly never thought was possible.

The team behind Zerene is my favorite part of the product. They care deeply about each Zerene user and take the time to help problem solve and analyze data. I’m looking forward to continuing my use of Zerene and watching my numbers get better and better. I highly recommend trying out Zerene and getting in touch with their wonderful team for yourself!

After a decade of grinding my teeth, it was pretty astonishing to see how quickly the biofeedback reduced the clenching within days! What surprised me too was how barely noticeable it felt while I was asleep – I only remember it buzzing maybe 4 or 5 times during the first week, even though it had actually gone off hundreds of times.

E
Emily

Definitely worked for me. It took some getting used to wearing it, but now I barely notice it and the biting/clenching is pretty much gone

M

Zerene is easy to use and really made a difference for me. The device is comfortable to wear, and has significantly reduced my jaw pain and discomfort with remarkably durable effect – after a month of use I now find I only need to use it a couple of nights a week. Customer support is as good as it gets. The data helps demonstrate the improvement the device provides, and helped me better understand how bruxism was impacting my quality of sleep. I fully recommend Zerene!

After trying the Sleep Guard headband and Clench Alert bite guard without success, Zerene has been a game-changer for my nighttime clenching. It’s far less invasive than other options, provides detailed data with actionable insights, and features tunable biofeedback that I can adjust for intensity and bite sensitivity. The results were clear both in the data and how my jaw felt each morning. What I appreciate most is that after an initial training period, I only need to wear it once every week or two for maintenance rather than every night. The Zerene team is also incredibly supportive and genuinely invested in your progress. If you’re struggling with bruxism, this product is absolutely worth trying.

R
Ryan

The Zerene team is amazing and super hands on, they truly want to help! The device is well engineered and the app is helpful for seeing all your data and tracking progress. Would recommend to anyone who is looking to improve their clenching/grinding symptoms

J

I was looking for a product to reduce my jaw pain and to slow the damage my clenching/grinding was causing to the enamel of my molars. Deep, restorative sleep is a top priority for my wellbeing and I needed a solution that was not disruptive. Zerene has been my answer. I was very pleasantly surprised at how little the device/training disrupted my sleep. And the amount of data provided is fascinating–seeing the near-immediate reduction in strength and frequency of clenching events is motivation to continue on. But most of all I have been impressed with the customer service. Real humans who want to work with you to find relief by customizing a program to meet your specific situation. Highly recommend.

S
Scott

I was surprised by how comfortable Zerene was when I first tried it. As a dentist, I am intimately aware of the relationship between compliance and comfort. Even though the device sticks out of the mouth, it was barely noticeable while I was awake and completely unnoticeable once I fell asleep. Wearing it is easy and free of discomfort. What I really appreciate is how it gives me clear insights into nighttime grinding – helping me finally understand bruxism patterns in a way I never could before.

Nacho

Zerene has been life-changing. My bruxism decreased by 85%, and I no longer experience jaw pain. It helps me not just with clenching but also makes me more mindful of my stress and habits, positively impacting my everyday life. I highly recommend it!

J
Julia

I’ve had headaches from teeth grinding for the last 10+ years. I’ve tried multiple headache pain meds, different types of mouth guards (hard and soft). Nothing has worked as good as Zerene. That’s because Zerene stops the *source* of my headaches – teeth grinding. I wish more people (& doctors) knew about Zerene! If you suffer from headaches from teeth grinding, I 1000% recommend Zerene. It’s worth every

Zerene is revolutionary for people suffering from bruxism. It’s different than any regular night guard (which I’ve had many) that just stops wear down of your teeth. Zerene provides the feedback (a little buzz) you need to reduce or virtually stop teeth grinding. The feature rich app provides customizations and data you need to understand your nightly habits. I definitely saw improvements with it. I paid more for a custom night guard several years ago, so it’s a great value.

G
George

Really cut down the amount of teeth grinding. Easy to use and clean. I would recommend this product to anyone who has this problem.

B
Ben

My teeth clenching activity reduced by over 75% while using Zerene! It took me a while to dial in the the right settings, and once I did, I couldn’t even tell the device was even there while I wore it.

J
John

All I can say is wow! In less than two weeks, my teeth grinding had decreased considerably! I felt better, was more rested, and am excited at the prospect of putting away my mouth guard forever. The daily data on how the previous evening went is super detailed and helpful, and the nightly instructions really help set the tone for a good night’s sleep. I highly recommend Zerene!

R
Rashard

Great product, and great results. I was a little apprehensive before I started because I didn’t know if the device would be uncomfortable and affect my sleep. To my surprise it’s extremely light and didn’t feel uncomfortable at all! It was great to be able to see the data and follow my improvements. Overall great experience that provided insight and quality results!

C
Caitlin

Extremely helpful! Was nice to be able to not wear a mouthguard all the time, and to find out about my patterns of night grinding.

C
Chris

I learned that being too hot during the night drastically increases my clenching – I appreciated the interesting insights like this that help me shift my norms.

Noah

Zerene delivered tangible results within the first week of active use. I was thoroughly impressed with the drastic reduction in my teeth grinding in such a short time span. I would recommend this product to anyone in search of a convenient remedy to their teeth grinding/clenching behavior.
