I can still taste a bad aftertaste even after rinsing several times with water. I thought that I was using the regular Listerine. Strangely enough I described the off-taste as like those zinc cold lozenges and then I read that this product contains a form of zinc to fight tartar. I believe that is what is causing the off-taste. It lingers for a long time--well after the mint taste leaves, and even after rinsing with water. I just brushed before bed and used this and feel I now have to eat something just to get the taste out.
No, I would not recommend this product
