It is not an absolute contraindication to breastfeeding after anesthesia for tooth extraction, but a specific analysis is needed. In case of simple tooth extraction, the extraction process is very smooth and rapid, and only local infiltration anesthesia is applied during the extraction process, breastfeeding is generally not affected. However, if the extraction of a more traumatic tooth takes longer and is more traumatic, and in addition to the application of anesthesia, other drugs including antibiotics are also applied, it is recommended that the patient suspend breastfeeding for a period of time. This is because once the antibiotics are applied, there is a risk that they will be transmitted to the child through breast milk. If the extraction is more traumatic and more damaging to the mother, it is recommended to recuperate for a period of time before breastfeeding.
