When wearing bridges, crowns or implants, reaching all areas and cleaning thoroughly can be difficult, but should be done if you want to protect your oral health. Consider using a specially designed floss. GUM Access Floss is super easy to use, thanks to a built-in threader. It allows you to easily guide the floss between your teeth, under and around crowns, bridges and implants. The floss also expands for more contact with the surface of the teeth, making it perfect if you have wider interdental spaces.
