I have been using the waterpik for a few years now. It really allows me to floss more. My mouth feels hydrated after using. I highly recommend this product if you don't like to manually floss with the traditional floss because this product makes it easy and fast to floss.
We had a small battery operated device. It didn't thrill my wife. Her new dentist recommendede and ourchased it for her. she get one to care for her new bridge. I found the Water Pic 100 in the drug store and purchased it for us. She thinks it is GREAT.
