ive always like listerine.... and now i love it!
By jokeymoke52 onListerine Whitening, first off, is the least burning mouth rinse ive ever used. it actually tastes great and doesnt burn at all. it is a clear liquid and the flavor is clean mint, and as you swish it around in your mouth it foams up. you are supposed to use it and then brush your teeth right after, which i love, because i always hate the extra mouth rinse in your mouth thats there even after you spit it out. but since you brush your teeth afterwords, it takes all the excess out with it. i used it for about a week or two and immediately started noticing a difference in the whiteness of my teeth... it really does work great at whitening your teeth! but my only con is, after only one week of daily use, my teeth became extremely sensitive... which is extremely not fun at all. i could barely breath without my teeth starting to hurt. but i guess if you use it like every other day or something, it might not do that. i dont know. but as far as whitening is concerned, it does great! no more annoying whitening strips or harsh chemical treatments, listerine solves all of that. it whitens your teeth and removes germs at the same time! and it tastes great too.

The sensitivity issue was noticed by my youngest daughter when I bought this for the children's bathroom. I had to go out and get sensitivity toothpaste so that she wouldn't have problems. We changed products and she's not complained again - there must be something in this that affects teeth negatively...perhaps something to do with the whitening aspect as some whitening agents can sensitize teeth - odd. It did work quite well otherwise though. Thanks for the info.
I have very sensitive teeth, so this probably wouldn't work for me. Nice review.
