Jane, you asked me the other day whether Closys mouthwash helps with gum pockets. Yes, very much. Prior to discovering Closys I'd had a rather poor evaluation during my dental cleaning. I try to be very conscientious about this and don't know why my gums suddenly got worse. I'd been using Closys daily for two weeks before my next cleaning and Viola! No problems! I was most impressed! No problems since then, either. I still see the hygienist every six months, but all I need now is a light cleaning and scaling. I'm sold on the product. Most of the reviewers on Amazon feel the same way.
