The most important function of the abrasive in toothpaste is to remove the sticky dextran film known as plaque. Abrasives such as calcium carbonate, silica, and aluminum oxide work mechanically to scrub away the buildup of plaque, which contributes to tooth decay, gum disease, and bad breath. While toothpaste may also contain antibacterial agents and detergents, the abrasive is essential for achieving optimal oral hygiene. Producing a shiny gloss on the teeth is a secondary function of the polishing agents in toothpaste.
