You've tried everything.
Nothing's fixed the grind.

Here's why: Night guards protect your teeth, but they don't stop the grinding. Botox wears off. Muscle relaxants leave you foggy. And sleeping with a bulky OTC guard in your mouth? Most people give up within weeks.

You're not failing treatment.
Treatment has been failing you.

97% reduction in grinding in just 23 days.

“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 penny.”

Julia

“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!”

Nacho

“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. Zerene has been my answer. I was very pleasantly surprised at how little the device/training disrupted my sleep. 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.

Jill

“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.”

Asami

“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.”

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.

How Zerene Works in 3 Steps

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 biofeedback-driven mouthguard and training program. 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.

Many Zerene users have found ways to arrange their Zerene so that it works with their CPAP setup. However, it varies greatly on a case by case basis. Zerene ideally needs about 2” of clearance as it comes out of your mouth, although users have managed with setups that allow even less space. If you have questions about using Zerene with your CPAP machine, please contact us.

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

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.
