After wisdom tooth extraction, you can eat ice cream, but do not eat particularly hard ice cream. Generally, after wisdom tooth extraction, it is recommended to eat cool and soft food, especially cold food like ice cream, which has a vasoconstrictive effect on the wound of the newly extracted tooth and can reduce the risk of swelling and bleeding of the wound, and also help the healing of the wound of the extracted tooth. Usually, it is not recommended to brush, rinse or lick the extraction wound with the tongue for 24 hours after the extraction, nor to suck on the extraction wound, which is to protect the blood clot in the extraction wound to prevent bleeding. As for eating, you can eat softer ice cream, ice cream, pudding, cold milk, egg custard, tofu, etc. All these foods can be safely consumed by patients after tooth extraction.
