Bests & Worsts Reviews from Amazon

I’m very particular about my teeth and so I’ve spent a lot of money on expensive whitening products. I saw the good reviews and figured I would give this a try. I have to say, I’m impressed. I noticed a difference after a single use. It’s also very easy to use and did not cause sensitivity to the gums. I especially like the application brush, which allows me to whiten individual teeth. I never understood why people bothered with the teeth that aren’t visible.
