Your teeth are covered with a sticky film called plaque that can contribute to tooth decay and gum disease. Plaque contains bacteria, which following a meal or snack containing sugar can release acids that attack tooth enamel. Repeated attacks can cause the enamel to break down, eventually resulting in cavities. Plaque that is not removed with thorough daily brushing and cleaning between teeth can eventually harden into calculus or tartar. This makes it more difficult to keep your teeth clean.
When tartar collects above the gum line, the gum tissue can become swollen and may bleed easily. This is called gingivitis, the early stage of gum disease. You can prevent plaque buildup and keep your teeth cavity-free by regularly visiting the dentist, brushing twice a day with a fluoride toothpaste and cleaning between your teeth with dental floss daily.
