Tooth extraction is not recommended when the patient is still in the menstrual period to avoid bleeding or infection caused by tooth extraction. Since tooth extraction is traumatic, the wound can easily clot into a blood clot under normal circumstances, and if the patient is in menstruation, it may cause bleeding or prolong bleeding, which will easily cause bacteria to invade and infect the wound, making the recovery after tooth extraction slow and even causing dry socket, so it is recommended to arrange tooth extraction 3-5 days after the end of menstruation. In addition, attention should be paid to the maintenance of oral hygiene after tooth extraction. Brushing can be done after 24 hours and gargling with light salt water can effectively achieve anti-inflammatory effects. If oral discomfort occurs during menstruation, women are advised to consult the dentistry department, and those who need oral treatment can take oral metronidazole and other drugs for anti-inflammatory treatment first, and then wait for the surgery at a later time after the period.
