Same patient, loose bridge with bad odor and caries beneath. What is the definitive treatment?

  1. Remove the bridge, regularize the margins, and recement
  2. Remove the bridge, remove the caries, and fabricate a new bridge
  3. Remove the bridge, apply fluoride, and recement
  4. Only adjust the bridge without removing it
Show answer and explanation

Correct answer: B. Remove the bridge, remove the caries, and fabricate a new bridge

  • A. Recementing over compromised abutments with caries does not eliminate the disease.
  • B. Correct. The definitive solution is to remove the bridge, eliminate the caries on the abutments, and fabricate a NEW, well-fitting bridge — the existing one has failed.
  • C. Fluoride and recementing leaves active decay and a failed restoration in place.
  • D. Adjusting alone does not address the underlying caries/leakage.
