5 simple ways to improve your oral healthToothpaste 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 serves as an abrasive that aids in removing the dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients to help prevent tooth and gum disease. Most of the cleaning is achieved by the mechanical action of the toothbrush, and not by the toothpaste.
