What is plaque?

Plaque is a sticky film of bacteria that constantly forms on teeth. Bacteria in plaque produce acids after you eat or drink. These acids can destroy tooth enamel and cause cavities and gingivitis (gum disease).

Plaque can also develop under the gums on tooth roots and break down the bones that support teeth. Untreated plaque can harden into tough-to-remove tartar. Proper oral hygiene, including daily brushing and flossing, gets rid of plaque.
