Customer ratings & reviews

Researched a few companies online before settling on Sentinel. My main grievance with the other night guard labs was that none of them answered the phone. Some didn't even have numbers to call (just emails) and they were slow to respond. Sentinel was prompt and happy to answer my million questions. They made me an exceptional comfortable and STURDY dental guard. Happy customer here! Thanks a ton!

Oh man what a deal! One night guard at my dental office is $650. I can get two for less than $200 here. Shall we say awesome??

I've continued to wear my night guard regularly and though it does take some getting used to, I have gotten used to it. The fit is spot on. No need for any adjustments. Ordering for my wife and daughter soon.

A++ Customer service!! Very pleased with my product..better than my dentist made

I'm a pretty hard grinder.. being that I've gone through a few night guards from my dentist which was getting really expensive. My husband did some research and he came across Sentinel and thought I should try them out. I was a little skeptical about taking my own impression at first but it ended up being pretty fun for my husband and I. We sent the impression back in a prepaid envelope. My nightguard came back in about 10 days and I was blown away with how well it looked and fit. I don't know why dentist charge so much seeing that companies like these don't have to. Getting ready to buy another as back up!

Love the glow in the dark case! Opened my mail in a dim lit room and the little box was glowing back at me! Perfect fit. Terrific experience!!

Your business is greatly appreciated! Thank You!-Brody

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

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

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.
