My "dental hygienist" recommended using a "waterpik" after I told her I hated using dental floss. I always thought that a "waterpik" was just hype. But she insisted so I bought this model, at a very "reasonable" price. After using it for the first time I loved the way my gums felt; my teeth also look cleaner than when I just brush. It takes a little bit of practice to get the right angle; the design of the product allows for a one handed operation. I can't wait to get back with my "hygienist" to hear her say how much my dental cleaning has improved.
