This is my second waterpik I have owned. I purchased a 2nd time same model as the first one was excellent in performance. It was recommended by my dentist a few years ago. I can't do without one now.
I bought two of these, one for my son and one for me, about a month ago. We haven't been to the dentist yet for checkups, but my mouth feels cleaner and I feel confident that the checkups will validate that. The device is easy to use and I actually look forward to using it twice per day.
We purchased this tool for for our daughter when she had an orthodontic appliance placed last month. It provides a great assist when toothbrush and floss alone do not accomplish the job of thoroughly cleaning teeth and orthodontic appliance after eating. Our daughter is completely sold on the Waterpik!
This is my second Waterpik; The first one, 2008, used constantly, probably 3 or more times per day. It still works, but will be my travel Waterpik. I can't live without it!!!
My mouth is a Plaque magnet. I have my teeth cleaned every three months to keep the plaque build up under control so as to avoid gingivitis which runs in my family.
Since using the waterpik, my check up have been greatly improved and my dental hygenist says my gums are now health.
