This is a mouthwash I found on sale at USA Drug for $3.99. I have been using it for about three weeks now. The directions say to swish for 30 seconds before brushing. As far as taste goes this is one of the better tasting mouthwashes, well at least the Fresh Mint flavor is. This mouthwash is supposed to remove tobacco tar from teeth and kill germs that cause bad breath. While it does do what it says I still just find the mouthwash to be average. Most mouthwashes I have used kill germs and prevent cavaties. I do not notice my teeth being any whiter after brushing than when I do not use this. Personally I think Crest Whitening Rinse mouthwash works better (see my other review- "Crest Whitening Rinse"). I read some other reviews of this mouthwash and almost all of the reviewers loved it. Maybe it is just me or maybe they do not make it as good as it used to be. I say try it out if you haven't and stay with it if you have and are satisfied. Maybe you will be more impressed with it than I was.
