What is the number one cause of periodontal disease?

The leading cause of periodontal disease is indeed plaque, which is a sticky film of bacteria that forms on the teeth. When dental plaque is not effectively removed through regular brushing and flossing, it can harden into tartar, leading to inflammation and infection of the surrounding tissues. This accumulation of plaque is critical because it serves as the primary source of the harmful bacteria that incite periodontal issues.

Plaque buildup can progress from gingivitis, characterized by inflammation of the gums, to more severe forms of periodontal disease if not addressed. While tartar and bacteria are significant factors in the disease process, they stem directly from the initial plaque accumulation. Therefore, recognizing plaque as the root cause highlights the importance of oral hygiene practices to prevent the development of periodontal disease.
