What makes this guard right
Dual-layer construction
Soft gel-like EVA inside, hard copolyester outside. The inner layer cushions your teeth and reduces TMJ pressure. The outer shell absorbs grinding force that would compress or wear through a soft guard.
Reduces jaw pain and TMJ discomfort
The combination of cushioning and force absorption addresses both the symptoms — morning jaw soreness and headaches — and the cause — sustained grinding and clenching throughout the night.
Hand-finished to your exact bite
Each guard is trimmed and polished by hand to the precise contour of your impression. Seats cleanly, stays in place, and won't shift position during the night.
What happens after you order
Place your order & email your scan
Choose your guard and check out. Then email the STL or PLY file from your dentist to info@sentinelmouthguards.com — we’ll confirm receipt and start manufacturing.
We finish your guard by hand
Your guard goes straight to manufacturing — no impression kit, no waiting. Our technicians hand-trim and polish it to the exact contour of your bite.
Protection arrives
Ships free with care instructions and a guard case to keep it safe between nights.

The Hybrid Guard
$161.50What's not in your guard
We use only dental-grade, FDA-compliant materials. Here's what you'll never find in a Sentinel guard.
Same material standards as your dentist
Sentinel's lab is FDA registered. Our finishing process meets the same standards your dentist's lab is held to — because we are one.
No leaching substances
You wear your guard 6–8 hours a night. Leaching is real — it happens when plasticisers migrate out of the material into your body. Every Sentinel material is selected specifically because it does not leach.
Not just BPA free — BPS free too
Many 'BPA free' products substitute BPA with BPS, which researchers believe may be equally harmful. Sentinel is free of both — and every other bisphenol compound.
Every guard is hand-finished in the USA by our dental technicians. No outsourcing. No exceptions.
The Sentinel Promise
The finishing process is what makes us confident enough to promise this. A guard that's hand-trimmed to your exact bite fits. And a guard that fits doesn't need a guarantee — but we offer one anyway.
100-Night Outcome Guarantee
Sleep on it for 100 nights. If you're not waking up better, return it. A $23 fee covers shipping and materials — everything else is refunded.
Three Attempts to Get It Right
Adjustments, remakes, and one complimentary redo impression kit in any combination. If the fit still isn't right after three attempts, we'll issue a refund minus a $23 fee to cover shipping and impression kit costs. Covered within your 100-night guarantee window.
1-Year Craftsmanship Warranty
Every guard is covered for one year against defects in materials and workmanship. We stand behind what we make.

Best nightguard I’ve ever owned. Customer service was so helpful. Ive tried several nightguard companies & this one is the best (without question).

This mouthguard fit very well on the first try! I used another company previously and had to send it back multiple times and just gave up since they never got it right.

I really like my new Sentinel Custom Dual Laminated Night Guard. The process was so simple. As soon as I put it in, I knew it was going to be so much better than my old night guard. The fit is perfect and it is so comfortable. I would recommend this product and company to anyone needing a night guard. And the price was a fraction of what my dentist wanted to charge for one.

I couldn’t be happier with my new mouth guard. My dentist was impressed as well. Thanks Sentinel
Not quite right?
If your grinding is heavier than moderate — waking with sharp pain, worn enamel, or you've ground through softer guards — the Hard Guard is the next step up.
