Also I have allowed to test this product on TRND. After about 3 weeks of trial period now I'm at the conclusion came the Listerine Zero the best products in whole range of Listerine. So far I have always Listerine TotalCare used and was "burning" of the the mouth repeatedly tormented anew. But since I have very narrow interdental spaces, where I did not even get through with dental floss, I'm on the mouth rinsing solutions depend. Now I love the daily dental hygiene finally fun again. I have even a bottle in the work taken and sink now there as well. In my lunch break My conclusion: Listerine Zero is exactly the right product for me for daily dental hygiene.
