Just ordered three more to last me for a few years. Thank you Sentinel. You've literally saved me hundreds. Hugs to you!

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.

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

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+++++++++
