What defines plaque in dental terms?

Plaque is defined in dental terms as a sticky mass that contains bacteria. This biofilm builds up on teeth and can contribute to dental problems like cavities and periodontal disease if not properly managed through oral hygiene practices. The composition of plaque primarily includes bacteria, which thrive in the mouth and can lead to the formation of acids that erode tooth enamel.

The importance of recognizing plaque as a bacterial mass lies in its role in the overall health of the oral environment. Effective removal of plaque through brushing and flossing is crucial for preventing the progression of dental diseases. Other options presented refer to different concepts in dentistry but do not define what plaque is. For instance, dental restoration materials and fluoride treatments are methods used in dentistry to correct or enhance dental issues, while oral hygiene products encompass a variety of items designed to help maintain oral health, rather than defining the biological nature of plaque itself.
