Great Mouthguard

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

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!

Durability Mouth Guard for Severe Teeth Grinding & Clenching

I was referred by a friend who praised Sentinel's mouth guards and customer service. I live in Wisconsin and was worried about the mail service being dependable and timely. To my amazement, the entire process was smooth and fast. I am very impressed with the exceptional quality of my night guard and the timeliness of the transaction. I can't express how grateful I am for this service. Incredible!

Fast service, high quality and the fit is fantastic!
