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!

So this might be a little gross but I had some stains on my teeth from sleeping with my mouth open. I had a deviated septum and it forced me to mouth breathe. It would dry my gums out and cause them to crack and I would have a little blood sitting on my teeth when i would wake. That and on top of being an avid coffee drinker I thought I was doomed. Their kit took the stains off my teeth so fast, I was really happy and I recommended this to my co-workers. thanks for giving me my smile back!

I love that I got to choose my thickness. I cannot sleep with anything thick in my mouth and the 1mm worked perfectly for me. Thanks

I used the "big spender" coupon and received a night guard plus the teeth whitening at a 20% discount. The dentists price for this would have been over $1000. So grateful to have found this service. -Merry

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!

Just a beautiful fit! Thank you!

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!

Thank you for your responsiveness and great service. Greatly appreciated:) -M. Massey
