I have used ProFresh for several years in exactly the way the directions prescribe. I am a teacher, and I want to have fresh breath every day and not have any worries about offending colleagues or students with malodorous breath. The product works superbly for fresh breath but also for clean teeth and gums. My dental checkups for the past several years while using ProFresh reveal hardly any plaque build-up and no cavities. It is a great and dependable product for oral hygiene. Research has shown that clean teeth and preventing gum infection support heart health as well, so there are many excellent reasons to use ProFresh. I highly recommend it, and was so grateful that someone recommended it to me!
