Which of the following best describes plaque?

Plaque is best described as a soft, sticky film of bacteria. This biofilm develops on teeth and consists primarily of bacteria, saliva, and food particles. When oral hygiene practices are not consistently observed, these bacteria can multiply, leading to the formation of plaque. This accumulation can result in tooth decay and gum disease if not removed regularly through brushing and flossing.

Understanding plaque's nature is essential in dental health because it highlights the importance of daily oral care routines. Maintaining clear information about the composition and implications of plaque can help guide patients in their hygiene practices to prevent dental issues. The other options, while they describe various conditions related to teeth and dental health, do not accurately depict the characteristics or implications of plaque itself.
