Not sure I really understand proper way to use it yet. Gift from Wife. Was expecting removal of Plaque after just a few uses. Maybe Professional Cleaning First and THEN it will keep Plaque Buildup at Bay longer than just Brushing. (I hate Flossing! It Hurts - and I'm not a Kid at 69!)
Late getting Professional Cleaning as last visit was for Crown and they took 11 X-Rays trying to get it JUST RIGHT! 11 X-Rays Scared Me!
