Customer ratings & reviews

LOVE it! Entire process was easy. The mold fits perfectly! Good job! I have worn a night guard in past which was ordered from my dentist at the much higher prices, and this Sentinel guard is even better than that one. I ordered the 2 mm dual guard. I barely notice it in my mouth and it fits snugly. I also am thankful it's BPA-free. Highly recommended for protecting your pearly whites!

Great night guard! Great price!

Comfortable fit. I wear this all day, every day. I've had mine for 8 months and so far it still looks brand new. I ordered the thickest version. Very pleased!

Hey guys, I've loved the nightguard so far - it's the most comfortable one I've ever had, and I now rarely find myself having dreams where I'm pulling hard candy or gum out of my teeth! Jeremy

I received my new mouth guard, at first I thought it was too tight. But I continued to were it and it stretched out to a good fit. Satisfied Customer. Gary C.

Sentinel Mouthguards were great and very responsive to my emails when I messed up the first package they sent me. The second one was just as quick in arriving and the final mouthguard was as well. I have only good things to say about this company.

The Sentinel impression kit to make your dental molds is well done.It comes with 2 mouth trays and two sets of putty for two impressions (if you make a mistake). Taking my impressions was easy and the custom guard that arrived fit my mouth perfect. It also came with a nice retainer case and instructions for cleaning. Happy customer!!

This is my journey- I started to notice the effects of my teeth grinding and needed to start protecting my teeth. Admittedly, I tried to go the cheap route at first. Those guards are about as useful as a hockey puck in your mouth. I went through another company before Sentinel but it didn't work out. I couldn't get my impression right and they wanted to charge me for another kit. Resulted in a refund. Sentinel had amazing reviews so I decided to give it a try. I wear my Sentinel guard every night. The fit is perfect. It has not changed shape and I've had it for over a year. My teeth sensitivity and jaw pain is gone. Sentinel is a life saver. Great company! Great product!

A wonderful company! VERY VERY happy with my guard!

I have been ordering from Sentinel since 2012. Customer service has always been so friendly and helpful. The night guards have helped my mouth tremendously. This is a great, affordable service. I love you guys!
