Toothpaste is a paste or gel dentifrice used with a toothbrush to clean and maintain the aesthetics and teeth. It generally contains abrasives that aid in removing dental plaque and food from the teeth. Toothpastes assist in suppressing halitosis and deliver active ingredients (most commonly fluoride) to help prevent tooth decay (dental caries) and gum diseases such as gingivitis. Toothpaste is used to promote oral hygiene.
