It is perfectly fine to eat ice cream after tooth extraction, and it can play a role in stopping bleeding and preventing more than one bleeding after tooth extraction, but you must start eating only about two hours after tooth extraction. After tooth extraction, you can eat some warm, cool, fine and soft food, mainly avoiding stimulating food such as too hot and too spicy, which can easily induce infection in the extraction wound and aggravate the pain of the extraction socket. After tooth extraction, you can not only eat ice-cream, but also apply cold compresses with iced mineral water to reduce the swelling. However, it is usually operated within 24 hours, and after 24 hours, hot compresses can be applied to promote the absorption of inflammation as soon as possible. Do not chew on the affected side for a week or so after the extraction to prevent food from falling into the extraction socket and causing infection, and after a week, the healing of the soft tissue is basically completed and you can eat normally.
