I use equate brand mouthwash everyday (listerine knockoff) and I actually have noticed a little brown-ness between my teeth... I figured it was just from all the cola I drink.
That really sucks, if I don't use it I have stanky breath but I don't wanna mess up my teeth
More to the point, I've used Listerine pre brush whitening rinse and have noticed positive results. After using it once or twice I immediately noticed a diff. and then it took much longer for further results but if I use it once a day and keep the cola and coffee to a minimum the results are undeniable.
