Dental Braces Common Issues and Troubleshooting 2 — Questions and Answers
Question 1: What is a common cause of canker sores for new braces wearers?
- Brackets and wires irritating the inner cheeks and lips (Correct answer)
- Bacteria introduced during bracket placement
- Allergic reaction to metal in all patients
- Fluoride released from adhesive
Correct answer: Brackets and wires irritating the inner cheeks and lips
New braces create rough surfaces that rub against the soft tissue of the inner mouth, causing minor abrasions that can develop into canker sores.
Question 2: What happens if a patient fails to wear their elastic bands as instructed?
- Treatment will take longer and bite correction may be incomplete (Correct answer)
- Brackets will fall off faster
- Teeth will become overcrowded
- The archwire will need to be replaced more often
Correct answer: Treatment will take longer and bite correction may be incomplete
Elastic bands provide force for bite correction that the archwire alone cannot achieve; not wearing them consistently prolongs treatment and may result in a suboptimal outcome.
Question 3: What is 'bracket failure' in orthodontics?
- When a bracket detaches from the tooth surface (Correct answer)
- When the bracket material cracks
- When the bracket changes color
- When the bracket causes root damage
Correct answer: When a bracket detaches from the tooth surface
Bracket failure refers to debonding — when the adhesive bond between the bracket and enamel fails, causing the bracket to come loose.
Question 4: A patient notices their archwire has come out of a bracket. What is the best first step?
- Call the orthodontist to schedule a same-day or next-day repair (Correct answer)
- Push the wire back in with fingers
- Cut the wire and attend the next scheduled appointment
- Continue normally since one bracket won't affect treatment
Correct answer: Call the orthodontist to schedule a same-day or next-day repair
A displaced archwire should be addressed promptly as it can cease applying the necessary force for tooth movement and may poke or injure soft tissue.
Question 5: What causes white spots on teeth during orthodontic treatment?
- Enamel demineralization from poor oral hygiene and acid buildup around brackets (Correct answer)
- The bracket adhesive bleaching enamel
- Fluoride treatment applied too frequently
- Normal bracket pressure on enamel
Correct answer: Enamel demineralization from poor oral hygiene and acid buildup around brackets
White spot lesions form when acid from plaque bacteria dissolves minerals from enamel around brackets, leaving permanent opaque white marks.
Question 6: What is gingival hyperplasia in the context of orthodontic treatment?
- Overgrowth of gum tissue around brackets from inadequate oral hygiene (Correct answer)
- Normal gum recession during treatment
- An allergic reaction to metal brackets
- Temporary gum redness after adjustment
Correct answer: Overgrowth of gum tissue around brackets from inadequate oral hygiene
Gingival hyperplasia is excessive gum tissue growth triggered by poor oral hygiene during braces treatment, which can partially cover brackets if untreated.
