What is the role of plaque in dental health?

1. It strengthens teeth

2. It leads to dental decay if not removed

3. It helps in tooth bonding

4. It improves gum condition

The correct answer is: It leads to dental decay if not removed

Plaque plays a critical role in dental health primarily due to its potential to lead to dental decay if it is not adequately removed. Plaque is a soft, sticky film of bacteria that forms on the teeth and along the gum line. When plaque accumulates, the bacteria produce acids that can erode tooth enamel, leading to cavities and dental decay. Regular brushing and flossing are essential to remove plaque and prevent the harmful effects that can result from its buildup. The other options suggest benefits or roles of plaque that do not align with its actual impact on oral health. For instance, plaque does not strengthen teeth or help in bonding; instead, it is associated with the erosion of enamel. Additionally, plaque can negatively affect gum conditions, leading to gum disease if it is allowed to accumulate. Understanding the harmful effects of plaque emphasizes the importance of maintaining good oral hygiene practices.
