      Acid

    • B.

      Age

    • C.

      Cavity

    • D.

      Caffeine

    Correct Answer
    A. Acid
    Explanation
    Tooth decay occurs when foods containing carbohydrates (sugars and starches) are left on the teeth. Bacteria that live in the mouth digest these foods, turning them into acids. The bacteria, acid, food debris, and saliva combine to form plaque, which clings to the teeth. The acids in plaque dissolve the enamel surface of the teeth, creating holes in the teeth called cavities, or caries.

    • D.

      5-6 minutes

    Correct Answer
    B. 2-3 minutes
    Explanation
    The recommended time to brush our teeth is 2-3 minutes. This duration allows for proper cleaning of all surfaces of the teeth and removal of plaque and food particles. Brushing for less than 2 minutes may not be sufficient to effectively clean the teeth, while brushing for more than 3 minutes may cause unnecessary wear on the enamel. Therefore, 2-3 minutes is the ideal duration for brushing our teeth.

    • A.

      With a hard toothbrush

    • B.

      With correct brushing

    • C.

      By increasing the force of brushing

    Correct Answer
    B. With correct brushing
    Explanation
    Cleaning our teeth better is achieved by using the correct brushing technique, which involves using the right amount of pressure, brushing all surfaces of the teeth, and using a proper brushing motion. Using a hard toothbrush or increasing the force of brushing may actually cause damage to the teeth and gums, leading to oral health problems. Therefore, the most effective way to clean our teeth is by practicing correct brushing techniques.

  • 10. 

    What is best for teeth?

    • A.

      Rinsing with mouthwash after each meal

    • B.

      Brushing 3 times daily

    • C.

      Brushing twice daily and flossing once a day

    Correct Answer
    C. Brushing twice daily and flossing once a day
    Explanation
    Brushing twice daily and flossing once a day is the best option for maintaining good oral hygiene and keeping teeth healthy. Brushing helps to remove plaque and food particles from the surfaces of the teeth, while flossing helps to clean between the teeth and along the gum line where a toothbrush cannot reach. This combination of brushing and flossing helps to prevent tooth decay, gum disease, and bad breath. Rinsing with mouthwash after each meal can be beneficial, but it should not replace the regular brushing and flossing routine.
