Customer ratings & reviews

I’m extremely pleased to discover this website. I wanted to thank you for ones time just for this fantastic read!! I absolutely enjoyed every part of it and i also have you bookmarked to see new stuff in your site.

Wonderful results! My dentist doesn't offer deals like this! Lucky to have found you Sentinel!

My dentist sells this SAME EXACT KIT for $400. Same gel, trays everything. So glad I found it on here. My teeth get so white so quickly with this stuff. Thank you for making this affordable!

I've been using the gel for only two days and I've already noticed a huge difference!! I definitely recommend! Satisfied customer!

Taking my dental mold was so easy, I mixed some putty together and placed it in the tray like a little snake. Simple enough. sent it back and got my custom trays! Very happy customer here!

Drink coffee? Smoke? Like soda? Then you should use this stuff. I have bad habits but you can't tell since I got my own custom mouth tray. Shit is bad arse!

Fast delivery Love my custom trays! I whiten during the day and no one even notices. A++++

This is a really good deal. My dental office wanted to charge me $400 for the teeth whitening. Found the same thing here for $150. The Zoom whitening gel lasts a really long time. You only need a little bit each time you apply it so 3 syringes lasts forever! Well worth it.

My teeth have never been whiter. Beautiful results. Thank you.

For years I've smoked cigarettes and I finally stopped. I thought I'd never be able to get whiter teeth but this stuff works. It took me about 7 consecutive nights to see a real improvement but what an improvement. Now anytime I need to touch up my teeth I just whiten for a couple of days & that's all it takes. My wife is pleased with the results as well. Thanks a bunch.
