After tooth extraction, there are relatively more things to pay attention to: 1. After tooth extraction, the doctor will generally give a cotton ball for him to bite, bite for about half an hour, spit out the cotton ball after half an hour, do not rinse your mouth within 24 hours after spitting out, and do not drink anything too hot, generally eat something cold to slow down the blood circulation around the wound and reduce his bleeding; 2. Do strenuous exercise, pay attention to rest. And spicy, stimulating food are not eaten first. It is not recommended to extract teeth during women’s menstrual period, but usually after 2-3 days after the period. If it is really painful and has to be pulled, do the appropriate treatment, such as applying ice for 24 hours after the extraction, and using some antibiotics prophylactically after the extraction to prevent the occurrence of infection.
