My dental hygienist badgered me into using a waterpik, so I finally relented because I am developing gum disease. I hate regular flossing because my teeth are so close. I discovered that I loved the water flossing and now do it more than once a day. It is so easy and refreshing. My only regret is that I didn't buy the model that also included an electric toothbrush because I have heard they are also good for your gums.
I love it. I've been using it now for a month and I can feel great improvement in my gums. I'm surprised that dental professionals are not recommending this product more.
