Digging the Durability Mouth Guard

This mouth guard fits perfect and is more comfortable than my previous one. Priced much better than what my local dentist wanted. Pretty painless experience overall. Canadians make note that you do have to pay for shipping the imprints to their lab.

Amazing for severe TMJ

Have gone through dozens of math guards for severe TMJ grinding and this is as good as what you would pay ten-fold for at the dentist, at least for me.

Great Mouthguard

I highly recommend this guard. It’s been a couple of years now and it’s still great. Thanks!!

Great product and service

I've ordered a dental retainer from my dentist which was very expensive. It cracked repeatedly and had to be replaced 3 times. I got tired of dealing with them so I decided to try Sentinel based on the good reviews. They've been so responsive, answered my questions promptly and sent out the kits quickly. The retainer has held up beautifully and they look as new as when I received them. Their Customer Service is excellent. I won't go anywhere else.

teeth grinder

As soon as I settled the mouth on my teeth, I knew this mouthguard was different. It feels bigger, thicker and can handle the grinding. I look forward to a long, happy relationship.

Great mouth guard.

Durability Guard is significantly stronger

This one is much tougher than the regular guard—I went through two of the regular ones, which both ended up snapping in my hands when I was drying them. This durability one is much stronger. It has gotten a bit scratched up by my molars but is still solid. Knowing what I know now, I would have started using mouth guards earlier and would have started with this one!

Comfortable and Effective

The Sentinel mouth guard is comfortable and prevents me from grinding my teeth at night. I have used them for about 10 years now and am on my third one.
