2. b) Tooth decay develops when oral bacteria feed on sugars from food residue left on the teeth. These bacteria produce acids that gradually erode tooth enamel, eventually forming cavities.

3. c) According to the World Health Organization, 60 to 90 percent of school-aged children worldwide have experienced tooth decay. It remains one of the most common diseases globally.

4. c) The best prevention includes brushing at least twice a day, using fluoride toothpaste, and visiting the dentist regularly. Eating a balanced diet and avoiding tobacco also helps protect oral health.

For the best results, always follow your dentist’s and dental hygienist’s guidance to maintain a healthy mouth and a bright smile.
