Customer ratings & reviews

Fantastic experience with a company that is on their game. Smooth, quick process. Even got a couple of night guard cleaning tablets in my package. Would highly recommend!

I really like these night guards. I do not like soft floppy guards. They always seem to move around in the mouth and stretch out over time. These are hard and actually snap on to my teeth. The edges are smooth and not rough to the tongue or gums. This is my second guard from Sentinel and I ordered the 2mm. I would order more.

No complaints! I was skeptical and nervous to take my dental impression but customer service was very helpful. They answered my questions and eased my concerns. My mouth guard fits well and has held up to my intense teeth grinding. Thank you!!

My nighttime grinding has not stopped ( I guess until there's a cure this is as good as it gets) but I am at least grinding away on some durable material instead of my teeth. I have noticed my jaw & facial pain has stopped & I am grateful for the two year warranty on these.

No complaints here. Price was righteous and works well even a year later. Looks professional/high quality and beats dental guards you'd pick up from a retailer like Walmart & CVS. Seriously, why buy junk like that when you can wait three weeks and get something fantastic that is fitted to your teeth and actually works!

I used this kit for a week before I left for a wedding and it worked GREAT! I was telling my friends about it at the wedding as well, Hopefully I got you some customers! THANKS!

A common question I am asked from other fighters is if the mouth guards are breathable and if they're thin or bulky. The answer is definitely yes they are extremely easy to breath and talk with, and you can get your mouth guard made as thick or thin as you want. I prefer the 2mm thickness. It's not bulky at all and I still feel protected.

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!

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

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!
