Plaque is a sticky film of bacteria that forms on your teeth. It develops when food particles mix with saliva and bacteria in your mouth. If not removed through regular brushing and flossing, plaque can harden into tartar, which can lead to cavities and gum disease. Keeping your teeth clean helps prevent plaque buildup and maintain good oral health. When plaque builds up, it can cause problems like bad breath and tooth decay. Regular visits to the dentist, along with proper dental hygiene, are essential for managing plaque. Using fluoride toothpaste and mouthwash can also help protect your teeth from cavities and gum disease.
