I bought my waterpic when shopping with my friends. It has been so helpful since I am getting older and it helps my teeth to be free of food particles, etc.
I have three dental implants now and my periodontist suggested that I get a water pik as it not only helps to remove plaque and food particles, but it massages the gum tissue around the implants. She suggested this model and I have enjoyed using it. I like the option of adding Listerine to the water for a refreshing feeling.
