GUM Dental floss Dental floss 50m Did you know that cleaning the spaces between your teeth every day, using dental floss or a brush, is as important as brushing your teeth? Flossing helps remove much more plaque than brushing alone. GUM® Access Floss is very easy to use, thanks to two rigid sections for easy insertion. It is particularly effective for cleaning under and around crowns, bridges and implants, as well as in large interdental spaces. During use, the floss expands further to adapt to different sizes of interdental spaces, for greater contact with the surface of the teeth.
