Under normal circumstances, you can eat warm and cold skin-egg thin meat porridge 2 hours after tooth extraction. You can drink ice water, cold milk or ice cream two hours after tooth extraction; you can also eat semi-liquid food and soft food, such as boiled skin-egg thin meat porridge or noodles. Don’t eat overheated food; once exposed to overheated food, it may cause blood vessels to dilate and cause bleeding. In addition, you cannot brush your teeth and rinse your mouth for 24 hours after tooth extraction. However, if you brush your teeth after 24 hours, you should not brush the extraction socket, so as not to dislodge the blood clot and infect the wound. Don’t suck the wound, don’t play musical instruments; try not to spit after tooth extraction, otherwise it will affect the wound healing and lead to bleeding. You should not take a hot bath or do strenuous exercise immediately after tooth extraction to avoid bleeding from the wound. After tooth extraction, you should follow the doctor’s instructions to do a good job of postoperative care, so as not to affect the recovery of the wound.
