1. Question 1: Brushing Frequency

   How many times per day is it generally recommended to brush your teeth for optimal oral health?

   • Once
   • After every snack
   • Twice
   • Three times
   Show correct answer

   Correct answer: Twice

   Explanation: Dentists recommend brushing twice daily to effectively remove plaque and prevent gum disease. Brushing once may leave more plaque behind. Three times daily is not necessary for most people, and brushing after every snack can damage enamel if overdone.

2. Question 2: Flossing Benefit

   What is the main reason flossing is recommended as part of daily oral hygiene?

   • It removes plaque between teeth
   • It whitens teeth
   • It replaces the need for brushing
   • It freshens breath
   Show correct answer

   Correct answer: It removes plaque between teeth

   Explanation: Flossing's primary benefit is removing plaque and food particles from areas a toothbrush cannot reach. Whitening and freshening breath are secondary outcomes, and flossing never replaces the need for brushing.

3. Question 3: Gum Health Sign

   Which of the following is an early sign of gum disease (gingivitis)?

   • Loose teeth
   • Bleeding during brushing
   • Severe tooth pain
   • Receding gums
   Show correct answer

   Correct answer: Bleeding during brushing

   Explanation: Bleeding gums while brushing often signals early gum disease. Receding gums and loose teeth occur in more advanced cases, while severe tooth pain is usually associated with other dental problems.

4. Question 4: Snack Choices

   Which snack is most likely to help maintain healthy teeth and gums?

   • Potato chips
   • Fresh apple slices
   • Sugar-sweetened soda
   • Sticky candies
   Show correct answer

   Correct answer: Fresh apple slices

   Explanation: Fresh apple slices help stimulate saliva flow and can gently clean teeth. Sticky candies and soda are high in sugar, increasing cavity risk, while chips can get stuck between teeth and contribute to plaque.

5. Question 5: Lifestyle Factor

   Which lifestyle habit is most commonly linked with an increased risk of gum disease?

   • Regular exercise
   • Tobacco use
   • Brushing after meals
   • Drinking water
   Show correct answer

   Correct answer: Tobacco use

   Explanation: Tobacco use significantly increases the risk of gum disease by affecting blood flow and healing. Regular exercise and drinking water have positive health effects, while brushing after meals is beneficial.
