Which local anesthetic is considered safe for use during pregnancy?

• A. Lidocaine (Xylocaine)
• B. Prilocaine (Citanest)
• C. Articaine (Septocaine)
• D. Mepivacaine (Carbocaine)

Answer: (A)

Lidocaine is the safest choice in pregnancy because it has the longest history of use with pregnant patients and is considered to have the most favorable safety profile of common local anesthetics. Clinically, it’s associated with minimal fetal risk when used at standard dental doses and with appropriate precautions. Epinephrine, when used in the recommended small amounts, helps keep the anesthetic localized and reduces systemic absorption, further protecting the fetus. The other agents either have less supporting pregnancy data or carry higher concerns (such as methemoglobinemia risk with prilocaine or less-established safety data for articaine and mepivacaine), making lidocaine the preferred option in obstetric dental care.
