When you drink and munch starchy or sugary foods, you're not only feeding yourself, you're feeding the bacteria that can cause plaque on your teeth. Plaque is a thin, invisible film of sticky bacteria and other materials that covers all the surfaces of all your teeth.
But if youâre not? The bacteria in tooth plaque are free to release acids that damage tooth enamel. Regular acid assaults on enamel can wear holes in teeth, commonly called cavities. If left alone, plaque build-up gradually hardens, creating tartar or calculus on your teeth. Tartar is petrified plaque. Once itâs there, you need the help of a dentist or dental hygienist - tartar cannot be brushed off. Tartar above the gum line also contributes to gingivitis, or gum disease.
