Which of the following statements about plaque is true?

Plaque, a sticky film that forms on the surfaces of teeth, is primarily composed of saliva, bacteria, and food particles. As bacteria interact with sugars present in the mouth, they produce acids that can contribute to dental decay and gum disease. Understanding the composition of plaque helps emphasize the importance of maintaining good oral hygiene practices to manage its accumulation.

The options suggesting that plaque can only form on teeth with cavities, builds up primarily in dry environments, or cannot be removed by regular brushing are misleading. While plaque can develop on all teeth, regardless of the presence of cavities, its formation really thrives in moist environments, such as the mouth, where saliva facilitates the process. Regular brushing is effective in removing plaque before it hardens into tartar, highlighting the importance of daily oral care in preventing dental issues.
