Our mouths are full of bacteria, food particles and mucus which allows a build up of plaque to form on the surface of our teeth. Brushing and flossing helps remove this plaque and helps keep our teeth and gums healthy. If brushing and flossing is neglected it will lead to a build up of tartar on our teeth. Tartar is a hardened form of plaque and bacteria which can only be removed by your dental professional.
