Originally Answered: Why does toothpaste help remove pimples? The clotting property of toothpaste reduces redness and swelling and prevents bacteria from spreading to other pores on the face. It dries out pimples and draws impurities out of the pores and reduces the pimpleâs size.
Fluoride in various forms is the most popular active ingredient in toothpaste to prevent cavities. Fluoride occurs in small amounts in plants, animals, and some natural water sources. The additional fluoride in toothpaste has beneficial effects on the formation of dental enamel and bones.Sodium fluoride (NaF) is the most common source of fluoride, but stannous fluoride (SnF 2), olaflur (an organic salt of fluoride), and sodium monofluorophosphate (Na 2 PO 3 F) are also used.ayered toothpaste requires a multi-chamber design (e.g. USPTO 5,020,694), in which two or three layers extrude out of the nozzle. This scheme, like that of pump dispensers (USPTO 4,461,403), is more complicated (and thus, more expensive to manufacture) than either the Marraffino design or the Colgate design.
