Review on 🦷 Watts Power 35% Teeth Whitening Gels - 8 Huge 10ml Gels Plus New FCP Enamel Gel - Dual Action for Surface and Deep Stains - 80ml - Made in The USA: Experience Effective Teeth Whitening for a Brighter Smile by John Ferguson

I used bleaching gels in the past, but nothing that strong. I started whitening with this product and in just 1 week my teeth that used to be slightly yellowish were noticeably discolored, I mean WOW what the heck what a difference! In just 10 days my teeth were almost completely white. Be careful with this substance, it is very strong. If any of this gets on your gums, you will feel pain and whiten your teeth; it goes away after a few hours but it's a little annoying when i look in the mirror. The only thing I have is a mineralizer; I have all this whitening gel and not enough mineralizer. Anyway, great piece, does its job!
