What is the primary function of dental floss?

The primary function of dental floss is to remove plaque and food particles from between teeth. This is crucial for maintaining oral health as plaque can lead to tooth decay and gum disease if not adequately removed. Dental floss is specifically designed to reach areas that a toothbrush cannot, particularly the tight spaces between teeth where food particles and plaque can accumulate. Regular flossing helps in preventing cavities and gingivitis, contributing significantly to overall dental hygiene.

While other options might relate to aspects of oral care, they do not represent the primary purpose of dental floss. For example, whitening teeth is typically achieved through specific whitening products rather than flossing. Freshening breath may result from the removal of food particles via flossing, but it is not the primary intended benefit. Polishing teeth is a function performed by dental professionals using specialized tools and pastes, which is entirely different from the daily home care function of floss.
