Left my mouth feeling clean .
not like the other products that give off a bad after taste.
really had the feeling of getting in between the teeth.
I was an avid user of listerine original but now that ive tried this product ive found a new favourite!

I've tried a few of the whitening pre-wash treatments and this Listerine one is the best.I seen results the very first time I used it,it has peroxide in it which really works at cleaning any stains and really whitening the teeth.I agree with the other ladies its a little strange how it foams as your swishing but that is the peroxide doing its thing.I swish for as long as I can then really brush my teeth to remove anything left behind.I haven't had any sensitivity issues yet but I don't use it daily.I like to use it about 2-3 times a week.I also use regular Listerine mouth wash the original light brown one with euculyptus in it.I just find Listerine products are really superior oral care products.
