Customer ratings & reviews

Worth it!! Had my dentist make me a guard and it was so bulky and uncomfortable I never wore it. Tried to get a refund but umm no. Found this company online and for $130 this was far less expensive than my dentist. Glad I did it! Fast, friendly service and my mouth guard fits like a dream. Thank you Sentinel team!

This guard is great! Fit is spot on. I highly recommend *****

I guess I wasn't staying still enough the first two times because the Sentinel lab contacted me and said my impression was distorted. I stayed perfectly still the third time and made sure I waited the full three minutes before I removed the tray. Scared me for a brief second because the putty was so hard I thought it was going to pull my teeth out!! But it came out just fine and I got a great fitting nighttime guard. Thank you for working with me :D

I screwed up my dental impressions. Both of them. I took too long to mix the putty both times. Guess I'm bad at reading directions. The company did send me a redo kit free of charge. I was successful the second time around and got my guards. They really do fit like a glove and my tongue is healed! I highly recommend your company! A+++++

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.
