dentífrico

Dentífrico is a paste or powder used with a toothbrush to clean teeth. Its primary function is to remove plaque, food debris, and stains from the tooth surfaces, thereby preventing tooth decay and gum disease. The active ingredients in dentífrico typically include abrasives, detergents, binders, humectants, flavoring agents, and therapeutic agents.

Abrasives, such as silica or calcium carbonate, physically scrub away plaque and surface stains. Detergents, like sodium lauryl sulfate, create foam that helps to loosen debris and distribute other ingredients. Binders help maintain the paste's consistency, while humectants prevent it from drying out. Flavoring agents, like mint or spearmint, make the product palatable.

Many dentífricos also contain fluoride, a mineral that strengthens tooth enamel and helps prevent cavities by making teeth more resistant to acid attacks from plaque bacteria. Other therapeutic agents can be added to address specific oral health concerns, such as sensitivity, gum inflammation, or tartar buildup.

The history of dentífrico dates back to ancient civilizations, with early forms made from ingredients like crushed bone, oyster shells, and charcoal. Modern dentífrico formulations have evolved significantly, with scientific research driving the development of effective and safe oral hygiene products. Regular use of dentífrico, combined with proper brushing technique, is considered a cornerstone of good oral health.
