1, you can eat something cold after tooth extraction. When eating, you should be careful not to eat anything too hot. You can eat ice cream, cold milk or frozen juice. Diet mainly eats porridge or semi-liquid food, not hard food. Don't brush your teeth or rinse your mouth within 24 hours after tooth extraction. Don't touch the wound with your hands after tooth extraction. Don't lick the wound with your tongue. If it hurts after tooth extraction, you can take painkillers.

2. After the wisdom tooth is pulled out, bite the hemostatic cotton ball or gauze, spit it out half an hour later, and then eat it two hours later. If you eat on your side without tooth extraction, you can eat cold food 2-4 hours after operation, because cold food can reduce swelling and relieve pain, and it can also constrict blood vessels and help stop bleeding. 4-48 hours after operation, you can eat semi-liquid and digestible food, such as egg soup, soft steamed bread, vegetable paste, porridge, boiled noodles and so on. Don't eat too hot. Too hot food will dilate blood vessels, leading to bleeding after tooth extraction. You can basically eat normally on the third day after operation, but try not to chew with the tooth extraction side.
