This is the first Waterpik I have owned. I only regret that I did not purchase one earlier. It does an excellent job. The unit is very easy to use and clean.
I thought when I brushed my teeth properly and wrinshed enough times with water that I had cleaned everything out of my teeth area. Now when I use the waster-pick I found there were some particles of food that were still there that have flushed out and my gums seem to be tightening around my teeth. I will get a report on how good I am doing when I go my dentist in another month.
I had a Waterpik years ago, but when I moved it got damaged and it took me years to get another. I am so glad that I did. I had been having trouble brushing one particular sensitive area. My dentist told me to, 'stop brushing my teeth as though I were scrubbing pans', but it was really difficult to break that habit. Then I remembered the Waterpik, purchased it and have the clean, clean pain free mouth. My husband is surprisingly using it and told me he finds himself using it a few times a day. it is so worth it
