- All Sentinel orders include a kit with enough putty for two attempts — purchase this only if you need additional attempts beyond the complimentary redo kit
- VPS putty is the same material standard used in professional dental practices
- Includes two tray sizes and full putty for a complete upper or lower impression
- Not suitable for patients with dental bridges, loose crowns, or recent dental work — consult your dentist first

Extra Dental Impression Kit
$15.00What'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.
