After wisdom tooth extraction, you can eat in about 2 hours, but there are certain precautions for eating: First, you should eat some warm, cool and soft food, either semi-liquid or liquid food, but do not use a straw, because the suction action is likely to cause more than bleeding from the extraction socket. Second, after eating, you can clean the oral environment in time, but do not touch the clot in the extraction socket, which will cause the clot to fall off. You can also take some water orally for cleaning to prevent infection in the extraction socket, but you cannot rinse your mouth within 24 hours after extraction. Third, drink water and take medicine after 2 hours, these are no problem and will not have any effect.
