  • Best Teeth Whitening Product I've Tried - Non Gum Irritating
Great product. I purchased this for a refill for my original teeth whitening kit. Works very well and is cost-effective as well. I've tried other products, and they have irritated my gums. This product not only whitens my teeth but also does not irritate my gums or teeth. I highly recommend this product for those seeking a great teeth whitening product. ... show more

  • Easy
iSmile is easy to use, just 10 minutes a day will help whiten your teeth. I had no sensitivity issues, which I was concerned about since I had burning with whitening strips in the past. Just wish the kit or refills came with more than three syringes of gel.

  • Really works but mouthpiece is hard to snap back after washing
This stuff really works, however the mouthpiece is awkward and hard to snap back together after using and washing it - they most definitely need to redesign the mouthpiece.

  • Definitely works
A must have! I noticed results after my first use, but consistency is key. I love that I don’t have sensitivity issues, something I’ve gotten after using great whitening strips. I will say, it helps to brush it on, that way you don’t get it on your gums but are still able to get in the crevices.

  • Finally, white teeth again!
This product does what it claims. It's very easy to use, just follow the directions. My teeth were stained with coffee and tea stains. The iSmile Teeth Whitening Kit took those stains away, and now I can smile without being so embarrassed. I will continue using this product. I have tried so many products with so many promises, as usual, with absolutely no results. You will get results with iSmile. Try it, you'll love it! ... show more
