Is wisdom teeth removal safe during pregnancy?

What does the evidence say about wisdom teeth removal during pregnancy?

1. General anesthesia for a procedure in the first half of pregnancy has been associated with a small increase in miscarriage risk in some studies, though most research hasn't found an increased risk of birth defects; local anesthesia and light sedation, used for most routine oral surgery, are a different category from full general anesthesia. 1
2. The second trimester, roughly weeks 17 to 28, is considered the ideal window for elective dental procedures like a wisdom tooth extraction, but acute pain or infection should be addressed at any point in pregnancy rather than delayed. 2
3. Lidocaine, the local anesthetic most commonly used in dental work, is FDA Category B and considered relatively safe in pregnancy at standard doses, up to about 7 mg per kg with a vasoconstrictor, and research hasn't found it increases fetal complications. 3
4. Nitrous oxide sedation is commonly listed as a first-trimester contraindication in dental sedation guidelines, though it may be used later in pregnancy for a patient too anxious to tolerate the procedure otherwise, as long as exposure isn't prolonged. 4
5. For post-procedure pain, acetaminophen is preferred over NSAIDs, which are avoided especially early in pregnancy; for a dental infection needing antibiotics, amoxicillin and certain cephalosporins or macrolides are considered safe, while tetracyclines are avoided because of effects on a developing baby's teeth and bones. 2

Is wisdom teeth removal safe in each trimester?

• First trimester. If a wisdom tooth becomes infected or acutely painful in the first trimester, it still needs to be addressed. Organogenesis, when the fetus's major organs are forming, happens in these early weeks, which is part of why elective, non-urgent procedures are more often pushed to the second trimester rather than done now.
• Second trimester. This is generally considered the preferred window for a planned wisdom tooth extraction, roughly weeks 17 to 28, when it can be scheduled without urgency. Local anesthesia and, if needed, antibiotics like amoxicillin are standard parts of the visit.
• Third trimester. Oral surgery is still possible in the third trimester if it can't reasonably wait, though your surgical team may factor in how long you can comfortably lie back in the chair and coordinate timing with your prenatal provider as delivery approaches.
