I recently had to get a second crown. And no matter how much I brush and floss, there always seems to be food impacted between the crown and adjoining teeth. The Waterpik gets that out and I no longer have a painful gum around the crown.
In the beginning, it was a process learning how to control the water but I got it down now. What is amazing to me is that even after brushing, the water pic still dislodges quite a few of food particles.
I bought this 3 weeks ago, at the advice of my hygienist , I can't wait till my next visit to see if she notices a difference in my gums health. It is so much more convenient and soothing than hand flossing, my mouth feels so much cleaner.
