A pregnant patient presents with an acute dental abscess. When should she be treated?

Correct answer: C. Immediately, at any stage of pregnancy

• A. The second trimester is the preferred window for ELECTIVE care — it does not apply to emergencies.
• B. In the third trimester the supine position becomes uncomfortable (aortocaval compression), which affects positioning, not whether emergency care is provided.
• C. Correct. Acute infection is an EMERGENCY and is treated at ANY point in pregnancy. Untreated odontogenic infection, sepsis, pain and fever pose a far greater risk to mother and fetus than definitive dental treatment does. Deferring urgent care is not an option.
• D. Delaying treatment of an acute abscess until after delivery risks spreading infection, systemic sepsis, and adverse pregnancy outcomes including preterm birth.

Note: Elective care is best in the second trimester. Emergency care is provided any time. Avoid supine hypotension by placing a wedge under the right hip to displace the uterus to the left.
