A flosser is a small tool designed to help clean between teeth.

A plastic flosser has a short piece of floss stretched between two prongs, with a handle that makes it easier to reach your back teeth. These disposable flossers are popular with kids and adults who find regular floss awkward to use. Some electric water flossers shoot a stream of water between teeth instead of using string.

People who floss regularly tend to have healthier gums and fewer cavities than people who skip flossing. While brushing cleans the surface of your teeth, flossing gets to the spots where problems often start.
