You can eat ice-cream after tooth extraction, but you should pay attention to eating ice-cream two hours after the extraction, and the amount should not be too much, and the ice-cream should not be too hard. The temperature of ice-cream is low, so eating ice-cream can help to constrict blood vessels, reduce local bleeding, reduce facial swelling, and relieve pain to a certain extent. After tooth extraction, you should also pay attention to the fact that you should bite down on the hemostatic cotton ball or gauze for at least half an hour, and then spit out the cotton ball or gauze after the initial hemostasis. Do not brush your teeth and rinse your mouth for 24 hours after tooth extraction, and do not eat too hot, too hard or spicy or irritating food. You can brush and rinse your mouth after 24 hours of tooth extraction, and pay attention to maintain good oral hygiene. If there is significant pain or bleeding, it is recommended to actively seek medical examination.
