Toothpaste works with toothbrushing to clean teeth and fight plaque bacteria. 1  Specifically: 2  Toothpaste contains abrasives which physically scrub away plaque. In addition, toothpaste abrasives help remove food stains from teeth and polish tooth surfaces. 3  Toothpaste delivers fluoride to the teeth. Fluoride incorporates itself into tooth enamel weakened by acid attack, making it more resistant to future acid attack from plaque bacteria and food. This is perhaps the most important function of toothpaste, and is responsible for the dramatic reduction of cavities in today's society. Some toothpastes contain ingredients which chemically hinder the growth of plaque bacteria.
Under new European cosmetics legislation, toothpastes are required to list all ingredients. In addition to water, toothpaste will normally contain the following basic ingredients: Abrasives. Abrasives are the cleaning and polishing agents in a toothpaste and account for about a third of the toothpaste by weight. Most abrasives are chalk or silica based. Examples are dicalcium phosphate, sodium metaphosphate, calcium carbonate, silica, zirconium silicate or calcium pyrophosphate.
