Plak is a term often used to describe a sticky, soft substance that can accumulate on teeth. It is primarily composed of bacteria, food particles, and saliva. If not removed through regular brushing and flossing, plak can harden into tartar, leading to dental issues such as cavities and gum disease. Maintaining good oral hygiene is essential to prevent the buildup of plak. This includes brushing teeth at least twice a day, flossing daily, and visiting a dentist regularly for check-ups and cleanings. Proper care helps ensure a healthy mouth and reduces the risk of complications related to dental health.
