Customer ratings & reviews

Teeth molds were easy to take and the staff is incredibly responsive. I had a lot of questions about taking my molds of my teeth but the staff was patient with me and guided me through it. My retainers came back within about 1 1/2 weeks after sending off the molds. If I ever want or need new retainers I will go through this company again.

Excellent mouthguard. Does not bother me at night or slip out. Actually fits better than one I had made my dentist. Will definitely buy from Sentinel again.

So excited! Just got my Sentinel teeth whitening kit and it is so comfortable to wear. Already have seen a difference in just two sessions. Can't wait to see what's going to happen after a month!

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!!
