What is a primary function of dentifrice?

The primary function of dentifrice, or toothpaste, is to remove food residue and stains from the surfaces of the teeth. This cleaning action is essential for maintaining oral hygiene because it reduces the buildup of plaque, a sticky film of bacteria that forms on teeth and can lead to cavities and gum disease if not effectively removed.

Toothpaste contains abrasives that help scrub the enamel gently while being safe for daily use. Additionally, it often includes detergents to help loosen food particles and enhance the cleaning process. Although toothpaste may contain ingredients that contribute to enamel strength and provide flavor, the fundamental purpose revolves around cleaning the teeth to promote overall dental health.
