Customer ratings & reviews

Great night guard! I used to buy the bulky boil & bite guards because I didn't want to pay the price but I always ground through them and ended up spending more money than if I would have just got a custom one! Fantastic fit and high quality. Couldn't be happier with my purchase!

Finally an affordable option! This is now my favorite company! Process was easy and mouth guard fits like a glove. I highly recommend.

My husband and I bought 4 guards from sentinel just so we would have a backup since we like to travel. So I should be able to write 4 different reviews right?? All of our night guards fit great. We are very happy with our whole experience with the company and recommended them to all of our friends. If you're sitting there reading these reviews not sure to make the buy, rest assured this company is the real deal. We are real people who are now customers for life!

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!
