Dental floss (or simply floss) is a cord of thin filaments used to remove food and dental plaque from between teeth in areas a toothbrush is unable to reach. The use of floss is commonly recommended in order to prevent gingivitis and the build-up of plaque. Namely, the American Dental Association claims that up to 80% of plaque can be eliminated with this method, and flossing may confer a particular benefit in individuals with orthodontic devices. However, empirical scientific evidence demonstrating the clinical benefit of flossing as an adjunct to routine toothbrushing alone remains limited.
