Which statement best describes plaque?

Plaque is best described as a soft film composed mainly of non-calcified bacteria and cannot be rinsed off the teeth. This is accurate because plaque is a biofilm that develops on the surfaces of teeth and contains bacteria, food particles, and saliva components. Its formation begins within a few hours after cleaning teeth, and over time, it can contribute to dental problems such as cavities and gum disease.

The reason plaque is not simply rinsed off is due to its adhesive properties, allowing it to stick firmly to the tooth surfaces. Regular brushing and flossing are critical for its removal, as rinsing alone is insufficient to eliminate it. Additionally, plaque can harden into tartar (calculus) if not removed, which further complicates oral hygiene. Understanding this property of plaque highlights the importance of maintaining a consistent oral care routine to prevent its buildup and associated dental issues.
