Customer ratings & reviews

Great value for the money!

Amazing company! Very easy, simple process!

Really liking these. My teeth are so sensitive now that my braces are off so I was hesitant to try this product. After reading the reviews I decided to try. This is a perfect option for me. The clear retainers fit perfect. No sensitivity and I'm loving the price!

This the only mouthguard I've ever been able to wear. It's worth every penny.

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!
