Pregnancy can be anesthetized with tooth extraction, but the following matters need to be noted: 1. To choose to perform tooth extraction surgery in the 4th-6th months of gestation, the embryonic development is stable at this stage, the physical condition of the pregnant woman is safer, and no large fluctuations will occur during tooth extraction. Anesthetic drugs such as lidocaine and articaine cannot harm the fetus through the placental barrier.2. To avoid the surgery in the 1-3 months of gestation, the pregnant woman is emotionally unstable at this stage and emotional tension can lead to miscarriage.3. Tooth extraction in the 7-9 months of gestation, pain and other stimuli may induce miscarriage, and it is also inappropriate to perform tooth extraction.
