Excellent Product!!
I bought this plaque remover last year as I get a bad build up of plaque at the back of my bottom front teeth & it is a game changer. When you use it you can see the plaque being broken down as the metal scraper touches it. You don't have to push or scrape at your teeth so you can't actually feel it working, you just see it!! I use it once a month now & I'm very happy.
