Question

Which of the following is the reason for the growth of harmful bacteria in our mouth?

• A. Brushing twice daily
• B. Food remains sticking in teeth for too long
• C. Eating green leafy vegetables
• D. Flossing regularly after brushing

Answer 1

The correct option is B Food remains sticking in teeth for too long

Harmful bacteria may grow in our mouth if food remains stuck in our teeth for too long.

The harmful bacteria changes the sugar present in food into acid. Acid formed due to the action of bacteria on sugar eats away the teeth and cause decay.

This can be avoided by brushing twice daily along with regular flossing. Eating healthy foods like green leafy vegetables also makes our teeth healthy.
