Shock-Zorbent Sports Mouth Guard
$129.00What'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.

Perfect for flag football! I ordered this for my daughter who plays high school football. Got it in green which is her school color. She loves it! She says she can communicate with her team. It looks good on her. She's happy and so am I! HIGHLY RECOMMEND!

A++++++ I wanted a mouth guard that I could talk with and this is it. I chose a thinner style and as soon as it came in I knew this was it. I was a little uneasy about taking my own dental impression but I got it right on the second try. The Sentinel team is fast at responding to emails and very helpful. My dentist wanted $400 for the same thing so I'm happy to have saved several hundred dollars. Grateful and blessed. <3

I ordered the clear custom mouth guard for BJJ and it fits exceptionally well. I don't worry about it falling out. In fact, I don't worry about it at all. I can talk with it in. I even forget I have it in! This is the best mouth guard I've ever owned. If you're on the fence, go custom! It's worth it.

I love the design and feel of these mouth guards. They look great and feel amazing. The lifespan is above average compared to other mouth guards I've owned. As is typical, the material will wear eventually but this is my 3rd one from Sentinel and they last me years. Sentinel Mouthguards material is better than other brands. What I LOVE about the feel is that it stays in place and it's thin enough that I don't want to take it out. As soon as I put it in I can feel quality. This is an important point because I need to be able to communicate with my team. Awesome mouth guards! Awesome company!

Smooth running machine! I'd give Sentinel Mouthguards 10 stars if possible. My experience has been nothing less than fantastic. The staff is very friendly and helpful. They replied to my emails promptly and took the time to answer my questions thoroughly. I sent off my dental impression and received my custom mouth guard within a week. The fit is so comfortable. They have FAR exceeded my expectations. Well ran team!

EXCELLENT QUALITY, GREAT FUNCTIONALITY!! I chose this company because I can customize the thickness. I only wear this for weightlifting so I didn't want a bulky mouth guard..very happy with purchase.
