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.
Results that Transform Lives

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.
