bacterial plaque
Học thuậtThân thiện
Definition
Noun: A sticky, colorless or pale yellow film that continuously forms on teeth. It is composed of mucus, saliva, food particles, and a dense colony of bacteria. If not removed regularly, the bacteria in plaque produce acids that can lead to tooth decay (dental caries) and can harden into tartar (calculus).
Usage
This term is used primarily in medical, dental, and general health contexts to describe the primary cause of common dental problems. - Regular brushing and flossing are essential to remove bacterial plaque. - The dentist explained that bacterial plaque buildup was the reason for the cavities. - Bacterial plaque is the main culprit behind gum inflammation.

Advanced Usage
