What is biofilm in the context of dental hygiene?

Biofilm, particularly in the context of dental hygiene, refers to a sticky layer of bacteria that adheres to tooth surfaces. This biofilm is a complex aggregation of microbial cells that develop into a protective structure, making it more resistant to removal than simple plaque. Regular dental cleaning practices, such as brushing and professional cleanings, are essential for effectively disrupting and removing biofilm from teeth and gums.

The presence of biofilm can lead to dental issues such as cavities and gum disease if not adequately managed. Understanding biofilm's composition and behavior helps dental professionals implement better cleaning techniques and educate patients on the importance of maintaining oral hygiene to prevent its buildup.
