What role does the presence of dental biofilm play in gingival diseases?

The presence of dental biofilm is recognized as the primary cause of gingival diseases. Dental biofilm, also known as plaque, is a dense, structured community of bacteria that forms on tooth surfaces. When biofilm accumulates and is not adequately removed through regular oral hygiene practices, it can lead to inflammation of the surrounding gingival tissues, a condition known as gingivitis.

Gingivitis is characterized by symptoms including swelling, redness, and bleeding of the gums. The bacteria present in the biofilm produce toxins and release inflammatory mediators, which trigger the body's immune response, resulting in the clinical signs of gingival disease. If the biofilm persists, it can progress to more severe forms of periodontal disease, where tissue destruction occurs, potentially leading to tooth loss.

Thus, understanding the role of dental biofilm is crucial in the prevention and management of gingival diseases. Effective plaque control through brushing, flossing, and regular dental visits is essential to maintain periodontal health and prevent the onset of gingival and periodontal diseases.
