It is possible to eat fish after wisdom tooth extraction, but it is necessary to pay attention not to make the fish too hot or too hard. Generally, it is recommended to eat warm, cool and soft food after tooth extraction, not to eat too hard or too hot food, because hard or hot food will physically stimulate the wound of tooth extraction and may cause the loosening and dislodging of blood clot in the wound of tooth extraction and cause bleeding in the wound of tooth extraction. Therefore, it is generally recommended to eat ice cream, egg custard, tofu and pudding after wisdom tooth extraction, while fish itself is not very hard and can also be eaten by patients after tooth extraction, but it is necessary to pay attention not to eat fish that is too hot or too hard.
