LISTERINE Whitening Pre-Brush Rinse, Clean Mint 16 oz (473 ml)

Comment: It is a good product and "pre-brush" realy means to use it before brushing. This is because it foams a lot in your mouth and leaves a bad after tastes that reminds you of plastic. This must be because of the whitening chemicals that they use which is why it is recogmended to be used before brushing so that the chemicals can be washed off. I give it 2 star because I do not like the tastes and it stays with you for a while after you are done. It is resticted in when you can use this since it isn't like mouthwash and you'll only use it where you brush your teeth. It's not something you can take with you to the office and such. I use it 2 times a day and so far it's been for about 1-2 weeks and I haven't noticed anything damaging to my mouth. It does clean and it doesn't effect my mouth blister at all. My mouth blister did get better but not sure if it was because of this or by natural means. I would not buy this product again or recomend this to a friend when there are other mouthwash out there that does the same and can be used at anytime without the need to brush.

Comment: Works great. My wife and I have been using this for months on the advice of our periodontist.

Comment: Dont listen to anyone who says this product doesn't have problems - they probably just haven't used it long enough (or work for listerine). While it does whiten teeth quite well it will also completely destroy the inside of your mouth! After about a month of using the product you'll start to notice the tissue on the inside of your mouth peeling away and forming long strands of white slime. If it sounds gross and uncomfortable it is! The whitening effect is not worth it.

I cant believe companies are allowed to put products like this on store shelves. If this stuff damages the tissue in your mouth so easily just imagine what else its doing that you cant see! Stick to the non-whitening listerine and stay away from the whitening variety at all costs.

Comment: My family has been using "Listerine Whitening MouthWash Pre-Brush Rinse" for 10 months or so, and we are very happy with the results. It is important to follow the directions and remember that you have to brush AFTER using this mouthwash.

We have noticed significantly whiter teeth on my teenage daughter and me. I am reasonably sure that this is not just due to brushing since these habits haven't really changed.

None of us have noticed a "film" in the mouth, sores, or loss of taste as some other reviewers have reported. Note sure if we are just lucky or doing something different.

So, for a product that works better than expected (with noticeable results), this is recommended!
