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+++++++++

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

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.
