Plaque is a buildup of substances including bacteria, food debris, and saliva that accumulates on the surface of teeth. It is a sticky, colorless film that can harden into tartar if not removed through regular brushing and flossing. Plaque can lead to a number of dental problems such as cavities, gingivitis, and periodontitis, which is a serious gum infection that can damage the soft tissue and bone that support teeth. It is important to maintain good oral hygiene by brushing twice a day, flossing daily, and getting regular dental check-ups to prevent the buildup of plaque.
