Identify the reason for formation of dental plaque.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Masses of bacterial cells together with food particles stick to the teeth.
- Dental plaque develops when mouth bacteria consume food remnants, especially sugars, and generate acids as a result.
- These bacteria, combined with food particles, cling to the surface of teeth, forming a sticky biofilm.
- If not eliminated through brushing and flossing over time, plaque can solidify into tartar, resulting in dental problems such as cavities and gum disease.
