Patients can eat ice on the 2nd day after tooth extraction, but it is not mandatory to eat ice. The doctor’s advice on eating after tooth extraction is to eat warm, cool and soft food after surgery. Some doctors will advise patients to eat cold ice cream after tooth extraction because the food is soft and the temperature is low, which will produce a cool stimulation to the extraction wound and make the blood vessels of the extraction wound contract, so as to reduce the swelling of the extraction wound. Of course, this is only a physical cooling relief for the extraction wound, and it is not necessary to eat ice after tooth extraction to make sure that bleeding will occur. Therefore, on the second day after tooth extraction, patients can eat ice cream at their own discretion, if they want to eat, they can eat ice cream, if they do not want to eat the wound and there is no bleeding, there is no need to eat ice cream.
