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

Man I did not know what I was missing. Everyone told me to go custom fit but I thought my chewed up, germ infested one from Academy was pretty good lol. You can't chew on this! It stays up there locked onto my teeth until its ready to come down. Amazing!! So comfortable. The difference is just unbelievable. Thanks Sentienl Team! Great staff btw

Great Mouthguard. I use it for football. It stays in place. I actually have to pop it out with my fingers after practice. I'm QB so I need to communicate. Perfect for me. Thanks!

Didn't follow the directions well enough the first time around and messed up my mold. Contacted Sentinel and they were super nice! Sent another putty kit right out. I got it the second time! My mouthguard fits flawlessly. Thank you!! A+++++++++

So nice to have a mouth guard I can actually wear! I've gone through a gazillion store bought ones and this is by far worth every penny. Two thumbs up! -Kirsten

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++++++++

I needed an extra thin mouthguard because I'm not competing in a contact sport (just dance- I have veneers). I got a thin clear guard and you can hardly tell I have anything in my mouth. Wonderful job! It's exactly what I wanted.

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!!

Honestly I dont know why people waste their money on over the counter guards. I will always buy custom and recommend them to everyone I come across. Here's some things to consider: You can breathe better. You can actually talk with it in your mouth and you can drink water without taking it out! Plus it has a really good warranty. I promote this company so much to my friends and family. Great job.
