Dental floss cleans the microbial dental plaque and food debris between the teeth. The types of floss are waxed, non-waxed, nentol, flouride, chlorhexidine. Flossing is recommended after brushing.

When flossing, the rope has to be wrapped on both middle fingers and guided by two index fingers. If the patient is unable to floss with this method, slingshot-shaped special tools, including rope docked on a holder which is angled properly for the mandibula and maxilla, can be used.

During flossing, it is recommended to go underneath the gum tissue and clean the whole surface with the motion of a seesaw and refrain from cutting the gum tissue. It is recommended to floss at least once a day.
