What is the primary function of dental floss in oral hygiene?

The primary function of dental floss is to clean between teeth and remove plaque. This action is crucial because toothbrushes often miss the areas between teeth where food particles and plaque can accumulate. Flossing effectively disrupts plaque and debris lodged in these tight spaces, significantly contributing to overall oral hygiene and preventing dental issues such as cavities and gum disease.

Choosing dental floss for cleaning between teeth addresses a unique and challenging area of oral care that toothbrushes do not adequately reach. Regular use of floss helps maintain healthier gums and enhances the effectiveness of oral hygiene routines. While options such as whitening teeth and freshening breath may be secondary benefits associated with good oral hygiene practices, they do not represent the primary function of dental floss. Therefore, the correct answer focuses on plaque removal and maintaining cleanliness in interdental spaces.
