You can eat ice cream after wisdom tooth extraction, but you need to be careful that the texture of the ice cream is preferably soft and not something like a plain popsicle. The medical advice after tooth extraction is to eat warm, cool, soft food, not hard or hot food. Hard and hot foods can physically irritate the newly formed wound, which may cause the blood clot to dislodge and cause secondary bleeding. You can eat cold foods including ice cream, pudding, cold milk, tofu, egg custard, rice porridge, all liquid foods can be consumed, but you must be careful not to eat hard or hot things as much as possible.
