A systematic review revealed stabilised stannous fluoride-containing toothpastes had a positive effect on the reduction of plaque, gingivitis and staining, with a significant reduction in calculus and halitosis compared to other toothpastes. Some stannous fluoride-containing toothpastes also contain ingredients that allow for better stain and calculus removal. At similar fluoride concentrations, toothpastes containing stannous fluoride have been shown to be more effective than toothpastes containing sodium fluoride for reducing the incidence of dental caries and dental erosion, as well as reducing gingivitis. Sodium fluoride (NaF) is the most common source of fluoride, but stannous fluoride (SnF 2), and sodium monofluorophosphate (Na 2PO 3F) are also used. The additional fluoride in toothpaste has beneficial effects on the formation of dental enamel and bones. Fluoride is present in small amounts in plants, animals, and some natural water sources. Fluorides įluoride in various forms is the most popular and effective active ingredient in toothpaste to prevent cavities. The American National Standards Institute and American Dental Association considers toothpastes with an RDA below 250 to be safe and effective for a lifetime of use. Toothpastes with RDA values above 250 are potentially damaging to the surfaces of teeth. The abrasive effect of toothpaste is indicated by its RDA value. Ībrasives, like the dental polishing agents used in dentists' offices, also cause a small amount of enamel erosion which is termed "polishing" action. The polishing of teeth removes stains from tooth surfaces, but has not been shown to improve dental health over and above the effects of the removal of plaque and calculus. Some brands contain powdered white mica, which acts as a mild abrasive, and also adds a cosmetic glittery shimmer to the paste. Representative abrasives include particles of aluminum hydroxide (Al(OH) 3), calcium carbonate (CaCO 3), magnesium carbonate (MgCO 3), sodium bicarbonate, various calcium hydrogen phosphates, various silicas and zeolites, and hydroxyapatite (Ca 5(PO 4) 3OH).Īfter the Microbead-Free Waters Act of 2015, the use of microbeads in toothpaste has been discontinued in the US, however since 2015 the industry has shifted toward instead using FDA-approved "rinse-off" metallized-plastic glitter as their primary abrasive agent. The removal of plaque inhibits the accumulation of tartar ( calculus) helping to minimize the risk of gum disease. These insoluble particles are designed to help remove plaque from the teeth. Toothpastes are derived from a variety of components, the three main ones being abrasives, fluoride, and detergent.Ībrasives constitute 8-20% of a typical toothpaste. However, the active ingredients in toothpastes are able to prevent dental diseases with regular use. A 2016 systematic review indicated that using toothpaste when brushing the teeth does not necessarily impact the level of plaque removal. Toothpastes may also help to control and remove plaque build-up, promoting healthy gums. Toothpastes containing fluoride are effective at preventing tooth decay. Toothpastes are generally useful to maintain dental health. Common colors for toothpaste include white (sometimes with colored stripes or green tint) and blue. Large amounts of swallowed toothpaste can be poisonous. ![]() The decline of tooth decay during the 20th century has been attributed to the introduction and regular use of fluoride-containing toothpastes worldwide. Owing to differences in composition and fluoride content, not all toothpastes are equally effective in maintaining oral health. Toothpaste is used to promote oral hygiene: it is an abrasive that aids in removing dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients (most commonly fluoride) to help prevent tooth decay ( dental caries) and gum disease ( gingivitis). Toothpaste is a paste or gel dentifrice used with a toothbrush to clean and maintain the aesthetics and health of teeth. Toothpaste from a tube being applied to a toothbrush ![]()
