It is possible to eat fish the day after tooth extraction. The medical advice on eating after tooth extraction recommends eating warm, cool and soft food, not particularly hard or hot food. As a kind of meat often consumed, fish has a very low fat content and is rich in vitamins, proteins and trace elements, which has a very good effect on human nutrition. For 24 hours after tooth extraction, patients are advised not to brush their teeth and rinse their mouths, and to eat mainly liquid, semi-liquid and soft food as much as possible.
