My dentist gave me a sample of this floss. Loved it, but couldn't find it in the stores. If you have crown or bridges, you will love it. I really like how it is made. Cleans better than regular floss!
Every 10 or 12 inches the floss is joined into a short piece of monofilament. Run the monofilament under the floss cutter pull the floss 90 degrees to the cutter and voila a piece of floss terminating at each end in monofilament. Simple to use, slides effortlessly under a bridge or through a tight spot leaving you to floss to your hearts content.
