Customer ratings & reviews

Fits like a glove! Just needed an upper. I have a permanent lingual bar. Taking my impression was fine. Make sure you take a deep impression because the gum area does need to be there. I highly recommend!!

A++++ fast shipping. Excellent correspondence & solid product. Thumbs up!!

Love my guard! Easy to use at home kit. I've sent several people your way since I received my dental guard. THank you!

Very happy! This is a great service for people like me who are on a fixed income and can't afford the dental office price. I'm elderly and I was nervous about taking my teeth impression but I did it and it was easier than I thought. I appreciate that they keep my impression on file for future orders. Good company with great staff!

Its better 2 or 3 mm for the thick?

I’m on my third nightguard right now and I could never go back! The nightguard fits perfectly and it is so comfortable. I can completely tell the difference when I don’t wear it. I absolutely love my nightguard! The service of Sentinel is great too! I had a crack in my guard, and they sent me one for free! I would highly recommend this! The only downside is that mine has calcium build up and has yellowed. I’d like to know how to avoid that.

Great company to work with. They'll make sure your guard fits right, and there is a real person on the other end of the phone.

My dentist always made a big deal of adjusting my night guard so I was really worried about this one needing adjustments but I did not need anything at all. It feel great & snaps into place. Makes me think my dentist was doing a bit of "rousing the stone". Happy customer!

Worth every cent! My teeth and jaw feel so much better. Thank you!

Awesome communication. The mouthguard fits perfectly. Very comfortable. If there is a problem they get right on it. Couldn't ask for a better company to purchase from and the mouthguard is very affordable. I love Sentinel Mouthguards.You guys are awesome.
