This stuff is amazing. I was so skeptical when i first started using it, but now I am in love. You use this before you brush your teeth , as soon as you start to swoosh it around it starts to foam in your mount , you rinse for a few minutes, spit it out and continue on with your routine . this has made my teeth so much whiter, and it doesnt leave a weird residue in your mouth . I use this almost everyday and I love it

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.

I would have to agree with all the other comments, it was really impressing how fast this worked. The only downside for me is that I have sensitive teeth, so after using it for a while it made them hurt a little bit. After a while I just started using it every other day along with some Sensodyne.

This really works. The difference in clear and my teeth are a lot whiter. I don't mind the fact that it foams in your mouth because you brush your teeth after using it. I would recommend this over whitening strips any day. It is a fast,affordable and convenient way to have whiter teeth.

This pre-brush treatment is really effective! Since I started using this product I have noticed a big difference in the colour of my teeth. It's a bit weird to use for the first time since the texture is different from ordinary mouthwash and it sort of foams in your mouth. But once you get past the texture, the results are really great! I find that the longer you wait to brush your teeth after using this product, the better the results. I usually use this pre-treatment, floss, then brush my teeth.

By far this is the absolute BEST pre-wash I have ever used !, I have nothing but good things to say about this mouth was, I saw results after the first day of using it, your supposed to rinse your mouth for 60 secs twice a day before brushing and it will whiten your teeth, its so amazing its like white strips without the high price ! I highly highly recommend it ! It's less then $10.00 and the benefit is amazing, anyone who wants whiter teeth should really look into buying this !, People literally now ask me how I get my teeth so white !
