Eating ice cream after tooth extraction is one of the explanations that some extraction doctors give to their patients after tooth extraction. Of course, this kind of tape itself has 1 certain individual difference, if for some elderly patients, or some patients with not so good gastrointestinal function, it is not very suitable to apply this method. There are 2 main reasons for eating ice cream after tooth extraction: one is that ice cream meets the requirements after tooth extraction. One is that ice cream meets the post-extraction requirements. We are asked not to eat foods that are too hard or too hot after tooth extraction because these two types of foods may cause physical irritation to the extraction wound, hard foods may cause damage to the extraction wound, and hot foods may form dilated blood vessels in the extraction wound. All these may cause bleeding. On the contrary, it is better to apply some cool and soft foods. The reason is that cooler and softer food, first of all, does not stimulate the extraction wound, and then, cooler food will relatively constrict the blood vessels at the extraction site, thus reducing the risk of bleeding. And ice cream precisely meets this 1 condition, so many doctors after tooth extraction will say to the patients after tooth extraction that they can eat some ice cream. Of course this is not absolute, you can also eat some other foods, such as cold pudding, cold milk, these are all safe to eat. It’s not just ice cream, but it’s okay to have some temperature, as long as it’s not too hot.
