What is dental plaque?

Dental plaque is accurately described as a soft, sticky biofilm of bacteria that forms on teeth. This biofilm develops when bacteria adhere to the surface of the teeth and proliferate over time, resulting in a thick, cohesive mass. The bacteria within dental plaque feed on sugars and produce acids as a byproduct, which can lead to tooth decay and gum disease if not removed through regular brushing and flossing.

Dental plaque tends to accumulate especially in areas that are hard to clean, such as between teeth and at the gumline. Its formation is a natural process that occurs continuously, which is why maintaining good oral hygiene is essential to managing it. If plaque is not removed, it can harden and develop into tartar, which is more difficult to eliminate without professional dental cleaning.

This understanding is crucial as it highlights the importance of daily oral care routines to prevent dental problems associated with untreated plaque, making option B the correct choice.
