These night guards are wonderful. My husband and I both purchased. We had not bought decent night guards since 2000 and I was tired of how quickly the "cheapos" wore out. We ordered these night guards and will continue to order more throughout the years. Don't waste your money: buy these instead!

I received my hard dental night guard & after two nights use I thought maybe I should have chosen the dual laminated guard. Contacted Sentinel & they happily complied with my request to change. By the time I received my new dual laminated night guard I had really adapted to my hard guard & decided to keep it after all (returned the dual laminated one). They were great through the process and went above and beyond to make a night guard that works for me. Highly recommended!

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

This is my 2nd Sentinel mouth guard - Sentinel is a great company, and I love the quality of the products and the prices are unbeatable!

I've never tried bleaching my teeth before but I was told this was the best kit to get by my friend who has really white teeth. This stuff works great.I noticed it working after the first night using it. It has been a little over two weeks and I have great results. I even took a before and after pic to make sure it actually works. Good stuff here 8-D

I wish I would have known I could get the same whitening kit sold in dental offices online for a portion of what they're charging. I was a little apprehensive about doing the moulding but I nailed it! My teeth trays fit like a dream and the gel is so fast and effective.

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

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!

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

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+++++++++
