Hey Kathryn, yes I forgot to mention the wonderfully clean, slick teeth I have now and fresher breath. Do you notice it helping with any calculus build up? I know I had some at one time on my lower teeth but I don't see it anymore. I was told that OP would not get calculus off, so I'm not sure whether to give credit to OP or not. But Yea!...no dentist visit for now. (refreshed 48124)
