Brown discharge after menstruation is considered to be related to the residual menstrual blood in the vagina and bleeding during ovulation, which can generally be extracted. If the patient has menstrual blood residue in the vaginal mucous membrane wall or due to the decrease of estrogen level in the body of ovulation, there will still be a small amount of brown secretion after menstruation, at this time the extraction of the tooth will not cause any other adverse reactions, and it can be extracted. For women who want to extract their teeth, they should pay attention to avoid the menstrual period, because the resistance of the body will be lowered during the menstrual period, and the extraction of teeth at this time is likely to cause localized infections that are not conducive to the healing of the wounds. For patients who still have brown discharge after menstruation, it is recommended to go to the gynecology department of a regular hospital, complete the relevant examinations, and then consider the cause of the disease.
