What causes periodontitis?
Periodontitis is caused by plaque, which unremoved, causes a gum infection which spreads to surrounding tissue. Plaque is a sticky film of bacteria that forms daily on our teeth. It reacts with the food we eat to produce acids and toxins that cause tooth decay. Newly formed plaque can be removed by brushing and flossing, but plaque that is not removed hardens into tartar or calculus. This hard layer of tartar forms at and below the gumline and cannot be removed by brushing. Tartar and plaque combine to accelerate tooth decay and irritate gums. The resulting inflammation and infection of the gums is called gingivitis. Untreated gingivitis creates pockets of plaque, tartar and bacteria between your teeth and gums. This spreads infection below the gums, eventually causing bone and tissue loss. This condition, known as periodontitis, is the biggest cause of adult tooth loss.
