Query: Feel great after water flossing

I like to use Waterpik Water Flosser after my flossing. It feel fresh and clean. My dentist suggested water floss to me as a gum massage tool to prevent gum disease.We will see if it help after 3 months when I go to see my dentist for check up. I have bought this device for one month. So far it work wonderful, no problem.
