Dental plaque is a sticky film of bacteria that forms on your teeth. It can cause cavities and gum disease. Hardened plaque, also known as tartar, is a more serious form of plaque that can only be removed by a dentist.
Tartar forms when plaque is not removed from your teeth for a long period of time. It is a hard, calcified deposit that can build up on your teeth above and below the gum line. Tartar can cause your gums to become inflamed and bleed. It can also lead to tooth decay and gum disease.
