(medical) a soft slimy substance formed on the teeth in which bacteria can grow
Plaque is a sticky, colorless layer of bacteria that forms on teeth. It develops when bacteria in the mouth mix with sugary or starchy foods. If not removed by regular brushing and flossing, plaque can harden into tartar, which is a hard and crusty buildup that can lead to tooth damage and gum disease. Regular dental hygiene is essential to prevent plaque buildup and maintain oral health.
