1. Question 1: Meaning of Gingivitis

   What does “gingivitis” mean when talking about gum health?

   • A type of oral cancer affecting the jawbone.
   • A permanent irreversible bone loss around the teeth.
   • Early-stage gum inflammation that can be reversed with good care.
   • A vitamin deficiency causing tooth loss.
   Show correct answer

   Correct answer: Early-stage gum inflammation that can be reversed with good care.

   Explanation: Gingivitis refers to the initial stage of gum inflammation, which can be reversed with proper oral hygiene. It is not permanent bone loss, which describes periodontitis. A vitamin deficiency can worsen symptoms but is not the definition. Oral cancer is unrelated to gingivitis.

2. Question 2: Bleeding Gums and Flossing

   If your gums bleed when you floss, what is the best approach?

   • Stop flossing completely for several weeks.
   • Continue flossing gently because bleeding often improves as gums heal.
   • Only floss once a month.
   • Floss harder to remove blood.
   Show correct answer

   Correct answer: Continue flossing gently because bleeding often improves as gums heal.

   Explanation: Gently continuing to floss helps the gums heal and stops bleeding over time. Stopping flossing allows plaque to build up, making bleeding worse. Flossing harder can injure gums, and flossing only once a month is not effective.

3. Question 3: Warning Sign of Gum Disease Progression

   Which symptom suggests gum disease is getting worse?

   • Teeth that appear slightly yellow.
   • Occasional sore jaw after chewing.
   • Short-term tooth sensitivity to cold drinks.
   • Persistent bad breath or gums pulling away from teeth.
   Show correct answer

   Correct answer: Persistent bad breath or gums pulling away from teeth.

   Explanation: Persistent bad breath and gum recession are key warning signs of advancing gum disease. Occasional jaw soreness, mild yellowing, or brief sensitivity are less directly related to gum disease progression.

4. Question 4: 2×2 Rule for Brushing

   What is the “2×2 rule” dentists recommend for brushing teeth?

   • Brush 2 teeth at a time for 2 hours.
   • Brush 2 times a week for 20 seconds each time.
   • Brush 2 times a day for 2 minutes each time.
   • Brush 2 times after every meal.
   Show correct answer

   Correct answer: Brush 2 times a day for 2 minutes each time.

   Explanation: The '2×2 rule' means brushing twice daily for two minutes each time, which optimally removes plaque. Brushing only twice a week is insufficient, brushing just two teeth misses most, and brushing after every meal is not necessary for most people.

5. Question 5: Brushing Technique for Gum Health

   Which brushing method is best for healthy gums?

   • Hard brushing for a shorter time.
   • Brushing only once at night.
   • Brushing without using toothpaste.
   • Gentle brushing—hard brushing can cause gum recession.
   Show correct answer

   Correct answer: Gentle brushing—hard brushing can cause gum recession.

   Explanation: Gentle brushing cleans well without damaging gums. Hard brushing increases gum recession risk. Not using toothpaste reduces cleaning effectiveness, and brushing only once daily may miss harmful plaque.

6. Question 6: Quick Self-Check for Gums

   How can you quickly check if your gums are healthy at home?

   • Gums must bleed during every cleaning.
   • Gums should be pink, firm, and not bleed on brushing or flossing.
   • Gums should feel numb and soft.
   • Gums should be swollen and bright red.
   Show correct answer

   Correct answer: Gums should be pink, firm, and not bleed on brushing or flossing.

   Explanation: Healthy gums are pink, firm, and do not bleed easily. Swollen, red, soft, numb, or bleeding gums indicate possible issues and are not signs of health.

7. Question 7: Smoking Effects on Gum Health

   How can smoking affect your gum health?

   • It reduces blood flow and hides bleeding while gum disease worsens.
   • It whitens teeth and improves gum strength.
   • It strengthens blood vessels in the gums.
   • It has no effect at all on the gums.
   Show correct answer

   Correct answer: It reduces blood flow and hides bleeding while gum disease worsens.

   Explanation: Smoking reduces blood supply to the gums and masks bleeding, even as disease may progress. It does not improve blood flow, whiten teeth, strengthen gums, or have a neutral effect.

8. Question 8: Importance of Cleaning the Gumline

   Why should you clean carefully along the gumline?

   • It prevents vitamin C loss.
   • It brightens the tongue.
   • Plaque collects there first and triggers gum inflammation.
   • It causes teeth to move if not cleaned.
   Show correct answer

   Correct answer: Plaque collects there first and triggers gum inflammation.

   Explanation: Plaque often accumulates at the gumline, causing inflammation if not cleaned. Not cleaning doesn't move teeth, affect vitamin C absorption, or directly brighten the tongue.

9. Question 9: Vitamin Deficiency and Gum Bleeding

   A deficiency in which vitamin can make gum bleeding worse?

   • Vitamin A
   • Vitamin B12
   • Vitamin C
   • Vitamin D
   Show correct answer

   Correct answer: Vitamin C

   Explanation: Vitamin C is important for gum health, and its deficiency may lead to increased gum bleeding. Vitamins A, D, and B12 are important for other aspects of health but not specifically for gum bleeding.

10. Question 10: Safe Home Rinse for Sore Gums

    What is a safe and simple home rinse for soothing sore gums?

    • Vinegar and baking soda
    • Warm salt-water rinse (½ teaspoon salt in a cup of warm water)
    • Mouthwash with bleach
    • Pure hydrogen peroxide
    Show correct answer

    Correct answer: Warm salt-water rinse (½ teaspoon salt in a cup of warm water)

    Explanation: A warm salt-water rinse is safe, inexpensive, and gentle for sore gums. Vinegar, peroxide, and bleach products are not recommended and can be irritating or harmful.
