Customer ratings & reviews

I was "already stoned" (love that) and received 20% off for already having my stone mould. I live in Ireland and shipping was quick and easy. Couldn't be happier with the Sentinel lab!

Big up to Sentinel Mouthguards for making a thin comfortable device I can actually sleep with. Thank you!

I got my guard today and I love it! It hugs my teeth softly and gives me the protection I need on the outside. I will definitely recommend this product!

So excited! I received my bite guard today. Fits perfectly and the look of it is very high quality. Can't wait to use it tonight and finally quit waking up with teeth and jaw pain. Thanks guys!

Lightening fast shipping, great correspondence throughout and excellent high quality product!

Just got my custom mouth guard in. Wanted to send a quick thanks! So much better than the store bought one I was using. World of difference! I will definitely be referring you to my friends, family, coworkers. Also, the glow in the dark case is super cool! Thanks, Trent

Hello Sentinel Mouthguards! Got my guard in today and it works and feels great! Thanks, Kim K.

Positive feedback rating. Very happy with my purchase

I have front upper porcelain veneers and just wanted something to protect my teeth while I sleep because I do grind a bit. I originally tried a one size fits all type from Walgreens and it was awful! Glad I found Sentinel. I love my night guard. It's so tiny and just fits perfect. A++++++++

Just wanted to say thank you for your work. I have multiple missing teeth and I have gone through other companies online. You guys have exceeded my expectations. The fit is perfect despite my very imperfect teeth. Thank you. Thank you. Happy holidays!!
