Toothpaste is a paste or gel dentifrice used with a toothbrush as an accessory to clean and maintain the aesthetics and health of teeth. Toothpaste is used to promote oral hygiene: it acts as an abrasive that aids in removing the dental plaque and food from the teeth, assists in the elimination and/or masking of halitosis, and delivers active ingredients such as fluoride or xylitol to help prevent tooth and gum disease. It is important to note that most of the cleaning is done by the mechanical use of the toothbrush, and not by the toothpaste.
