Discover fundamental questions about orthodontic care, braces, and daily habits for dental health in an easy, approachable quiz format.

This quiz contains 10 questions. Below is a complete reference of all questions, answer choices, and correct answers. You can use this section to review after taking the interactive quiz above.

1. Question 1: Main Role of an Orthodontist

   What does an orthodontist mainly treat?

   • Gum infections
   • Misaligned teeth and jaw bite problems
   • Tooth decay and cavities
   • Dental implant procedures
   Show correct answer

   Correct answer: Misaligned teeth and jaw bite problems

   Explanation: Orthodontists specialize in diagnosing and treating misaligned teeth and jaw bite problems. While tooth decay and gum infections are usually treated by general dentists or periodontists, and dental implants fall under prosthodontics. Orthodontists do not focus on these other dental issues.

2. Question 2: Orthodontic Devices

   What is the common name for devices used in orthodontic treatment?

   • Braces
   • Bridges
   • Dentures
   • Crowns
   Show correct answer

   Correct answer: Braces

   Explanation: Braces are the most common devices used in orthodontic treatment to straighten teeth and correct bites. Bridges and crowns are restorative dental devices, and dentures are removable replacements for missing teeth—not orthodontic appliances.

3. Question 3: Overbite Definition

   What is meant by an 'overbite' in dental terms?

   • Upper front teeth overlap the lower front teeth too much
   • Not enough teeth have grown in
   • Lower front teeth are in front of upper front teeth
   • Teeth are spaced too far apart
   Show correct answer

   Correct answer: Upper front teeth overlap the lower front teeth too much

   Explanation: An 'overbite' refers to the upper front teeth extending too far over the lower front teeth. Lower teeth in front indicates an underbite, spacing too far apart is called spacing, and lack of teeth is not the definition of overbite.

4. Question 4: Underbite Definition

   What describes an 'underbite' in orthodontics?

   • Teeth are unusually small
   • Upper teeth cover lower teeth completely
   • Lower front teeth sit in front of the upper front teeth
   • Gums are red and swollen
   Show correct answer

   Correct answer: Lower front teeth sit in front of the upper front teeth

   Explanation: An underbite is when the lower front teeth sit in front of the upper front teeth. Teeth that are small refers to microdontia, upper teeth covering lower completely is a severe overbite, and red, swollen gums are a sign of gum disease.

5. Question 5: Crowding in Orthodontics

   What does 'crowding' mean in orthodontics?

   • Teeth are too white
   • Gaps between all teeth
   • Having too many baby teeth
   • Not enough space, so teeth overlap or twist
   Show correct answer

   Correct answer: Not enough space, so teeth overlap or twist

   Explanation: Crowding occurs when there isn't enough space for teeth to align properly, causing overlap or twisting. Gaps refer to spacing, too many baby teeth is a different issue, and tooth color is unrelated to crowding.

6. Question 6: Spacing Definition

   What does 'spacing' in orthodontics refer to?

   • Teeth that have cavities
   • Teeth that are sharp or pointed
   • Teeth that are loose and wobbly
   • Gaps between teeth due to extra space or missing teeth
   Show correct answer

   Correct answer: Gaps between teeth due to extra space or missing teeth

   Explanation: Spacing refers to extra gaps between teeth, which can result from extra space or missing teeth. Loose teeth, sharp teeth, and cavities are unrelated to spacing as defined in orthodontics.

7. Question 7: Braces Adjustment Frequency

   How often are braces typically adjusted during treatment?

   • About every 4–8 weeks
   • Every day
   • Only at the beginning and end
   • Once every year
   Show correct answer

   Correct answer: About every 4–8 weeks

   Explanation: Braces are usually adjusted by an orthodontist every 4–8 weeks to gradually guide teeth movement. Annual, daily, or single adjustments at the start and end are incorrect and do not reflect standard orthodontic practice.

8. Question 8: Foods to Avoid with Braces

   Which type of food should be avoided if you have braces?

   • Mashed potatoes
   • Hard, sticky foods like caramel or chewing gum
   • Yogurt
   • Applesauce
   Show correct answer

   Correct answer: Hard, sticky foods like caramel or chewing gum

   Explanation: Hard and sticky foods can damage braces and should be avoided. Mashed potatoes, yogurt, and applesauce are soft foods that are generally safe for those with braces.

9. Question 9: Purpose of a Retainer

   Why do people wear a retainer after having braces or aligners removed?

   • To prevent teeth from becoming sensitive
   • To clean teeth after meals
   • To whiten teeth
   • To keep teeth in their new position
   Show correct answer

   Correct answer: To keep teeth in their new position

   Explanation: Retainers help maintain teeth alignment after braces or aligners, preventing teeth from shifting back. Cleaning, sensitivity prevention, and whitening are not the main purposes of retainers.

10. Question 10: Sign to See an Orthodontist

    What is one sign that you might need to see an orthodontist?

    • Difficulty chewing or a bite that feels off
    • Mild tooth sensitivity to cold
    • Mild gum bleeding from flossing
    • White spots on tongue
    Show correct answer

    Correct answer: Difficulty chewing or a bite that feels off

    Explanation: Difficulty chewing or a bite that does not feel correct can indicate bite alignment problems best evaluated by an orthodontist. Sensitivity can have other causes, mild gum bleeding is a gum health issue, and white spots on the tongue are unrelated to orthodontics.
