1. A type of dental tool

2. A nutrient-rich gel

3. Substance accumulating on teeth from food and bacteria

4. A dental procedure

The correct answer is: Substance accumulating on teeth from food and bacteria

In the context of dental care, a plaque refers to the substance that accumulates on teeth as a result of food particles and bacteria. This sticky, colorless film forms on the surfaces of teeth and can lead to various dental issues, including cavities and gum disease, if not properly managed through regular oral hygiene practices. Plaque is composed primarily of bacteria and their byproducts, which can irritate the gum tissues and lead to inflammation, a condition known as gingivitis. If plaque is not removed through brushing and flossing, it can harden into tartar, making it even more difficult to clean and increasing the risk of more serious dental problems. Understanding what plaque is and how it forms is crucial for maintaining oral health, as it highlights the importance of diligent dental care routines, including regular dental check-ups and cleanings.
