Correct answer: D — Remove the overhang and restore contour

A proximal overhang is a local plaque-retentive factor that must be corrected to allow periodontal healing and effective hygiene. Antibiotics without removing the local factor are not appropriate. The pearl is that restorative contour and periodontal health are inseparable around proximal margins.
