Negative Positive
Title: Very Good
Review: It works well. I brush and floss but I am "older" and have started to develop gum disease. Had I known that this could be an important tool keep my teeth and gums healthy, I would have bought one a long time ago. So now I floss, brush and then use the Waterpik. This is just in addition to your regular routine. It feels good when you use it.
