What describes plaque?

Plaque is accurately described as a sticky film that forms on teeth and is composed of microorganisms, primarily bacteria. This accumulation occurs constantly and can develop within hours after brushing. The bacteria in plaque produce acids that can lead to tooth decay and gum disease if not managed through regular oral hygiene practices.

Understanding plaque as a biofilm highlights its complexity as it is not just a single layer of bacteria, but a structured community with a protective matrix that allows the bacteria to thrive. This emphasizes the importance of daily brushing and flossing to disrupt plaque formation and prevent its harmful effects on oral health.

The other descriptions do not fully capture the nature of plaque. For instance, calling it a chemical substance does not encompass its biological aspect, while suggesting it forms immediately after brushing overlooks the timeline of plaque development, which involves a gradual accumulation of bacteria. The notion of plaque being an energy source for teeth is misleading, as plaque itself does not provide nourishment to teeth; rather, it poses a threat by generating decay-inducing acids.
