I started using a Waterpik waterflosser a little over a year ago. I wanted to help ensure my gums were strong and not solely rely on flossing after going to the dentist and having a Waterpik recommended to me. For the past 12 years or so I have had some gum recession on my upper gums along each side (like where vampire fangs would be), presumably from brushing too hard. It was especially bad on the right side. It was ugly, the exposed root was yellow, it was sensitive, and food would get caught every time I ate. But I did not expect the Waterpik to fix that. To my shock, after 6-12 months of using it every day, I saw that my gum recession had all but disappeared. I wasn’t getting food stuck, and I wasn’t embarrassed of my appearance. Hardly any recession remained. Thought I’d write a post about it in case anyone wants to try this. I honestly had thought that at some point I’d have to pay for expensive skin grafting If I ever wanted to fix it. However, a $35 cordless Waterpik did the trick. Hope this helps someone!
