Menstrual period During the menstrual period, the hormone level in women’s body is changed, and tooth extraction at this time is likely to cause bleeding. In addition, the stress capacity of the body decreases and the fibrinolytic enzymeogen-activating substance in saliva increases, which makes the wound heal slowly and is prone to bacterial infection when the wound is in contact with saliva after tooth extraction. Pregnancy Women should not have their teeth extracted during the first and second trimesters of pregnancy. This is because irritation of the mother during this period can easily cause miscarriage and preterm delivery. For those who have a history of miscarriage or premature birth, tooth extraction should be avoided during this period. Furthermore, after tooth extraction, some people may need to take antibacterial drugs, and certain drugs and their metabolites may reach the fetus through the placenta, causing adverse effects on it. During breastfeeding When teeth are extracted during breastfeeding and antibacterial medication is needed, the medication and its metabolites can affect the baby through the breast milk. During the contraceptive pill The contraceptive pill can increase fibrinolysis in the body, so that the wound cannot form a good blood clot, and germs can easily take advantage of the situation to cause infection and affect wound healing. In addition to the above-mentioned special periods, patients suffering from diseases of blood, cardiovascular system or liver disease, kidney disease, hypertension, diabetes and other diseases also need to be cautious in tooth extraction. So, when is the best time for women to have their teeth extracted? According to some information, it is most appropriate for women to have their teeth extracted around the 10th day of their menstrual cycle, when the wound heals faster and bacterial infection is less likely to occur.
