Customer ratings & reviews

I love my current guard so much, I ordered 4 more during your black Friday sale! The difference between your price and the dental office is exceptional!

I love my first night guard. Had some dental work done so ordering my second! I suffer from TMJ and this guard I wear for my lower teeth. It helps greatly with my jaw pain. No more popping and clicking since I started using it. The Sentinel team is fast, courteous and the product does the job at a price way lower than my dentist. Amazing!

Wish I would have known about this service years ago. Got talked into paying $500 for this at my dentist. You guys have saved my smile and my pocketbook! Thank you <3

This service is remarkable! The customer service is fantastic. Easy process to take my impression and the guard fits perfect. Thank you Sentinel!

Two things: I LOVE this night guard and it was the process was much faster than I had expected. As soon as I took it out of the package I knew it was high quality. The fit is better than any other night guard I've worn. Will definitely be using this service again.

I love my mouthguard that I ordered last year in August and unfortunately I cracked the back piece where my molar grinds down on the guard. Sentinel sent me a free replacement. I received it so quickly and it fits perfectly. Thank you for taking care of your customers!

Fast relief! Allows damaged areas to heal! This was several hundred dollars cheaper than my dentist and the quality of the product is impressive. The entire process was quick and easy. Customer service is great! I have no complaints. Would buy again!

I know first hand that this is a good deal because my dentist office has this exact same at-home teeth whitening system and it is being sold for $500! I looked online to see if I might get lucky and there it was. This gel is a very good teeth whitening gel and I love that you can reuse it unlike the whitening strips. Excellent product, fast delivery, and free shipping. Can't beat it!

Best thing on the market for my poor tongue! I have tried everything!! This is the only product that actually works. If you have a tongue biting problem like I do, try it. It works!

The impression is easy to take and the quality exceeds its price. I like that I can get a replacement for free if I grind through this one within 6 months AND that I don't have to take my impression again (they hold on to it). The way my stress level is, I might be grinding through this quicker than I think!
