Listerine Whitening Mouthwash

This stuff is great, and I saw that my teeth were dramatically whiter within a week of using this morning and night, twice a day, right before I brush my teeth. I'll admit I'm a whitening product junkie, and was considering doing to the dentist of get it done with a laser, because products like white strips and other gels and toothpastes wouldn't whiten my teeth the extra few shades I wanted, but this worked and I'm so glad i gave it a chance. It can be a pain in the butt to swish it around it your mouth for the full 60 seconds, since it foams a lot, and it burn the first few times, but like anyhting, you get used to it. However, it does work so i think it's worth it, all the way. it was pretty cheap too, around 5 dollars, and the bottle I got lasted me about a month.
