Hi all,

My husband is one of those people who insists on using (what I consider strong and unnecessary) mouth wash liquids. He's a fan of Listerine (he usually buys the green one, which I think is very strong).

I have been trying to talk him into not using it, since I've read that they kill both the bad and the good bacteria and could also maybe contribute to mouth or throat cancers. I am, of course, not sure what exactly is true, but I tend to be on the cautious side.

How safe are these rinses?
