Show answer and explanation

Correct answer: A. Immediately — acute infection and uncontrolled pain pose more risk than treatment

A. Correct. The second trimester is the preferred window for elective care, but genuine emergencies are treated whenever they occur. Untreated infection and pain carry real maternal and fetal risk.
B. Waiting weeks with an acutely inflamed pulp invites spreading infection.
C. The second trimester preference applies to elective procedures, not emergencies.
D. Antibiotics do not address the source; the inflamed pulp must be removed.
