When I went to the dentist for a followup from one 4 months prior, I hoped my gum situation had improved. When I had a "'cuff' check" I had lots of 4's, 5's and even a couple of 6's. They told me things were getting worse. I got some treatment and the dentist and they they said to use a Waterpik water jet on my gums every day.
4 months later, after using the Waterpik every day, I went back and my "cuff check" numbers ere 2's. 3's . . . only a few 4's and one 5. (cuff of gum around teeth and golf scores -- lower is better)
I'm ready to do a product endorsement for Waterpik.
