On the second day of tooth extraction, it is recommended to use warm, cool, thin and soft food, and not to chew food with the side of the tooth extraction, and it is better to quit smoking and alcohol. Do not eat particularly hot, spicy and hard food, which may cause irritation to the extraction wound and be detrimental to the healing of the extraction wound. After tooth extraction, it is recommended to eat mainly liquid and semi-liquid food, such as milk, noodles, bread, porridge, etc. When the extraction wound gradually heals and the pain and redness of the extraction socket disappears, you can gradually transition to normal food, and at the same time, ensure sufficient rest and do not do strenuous exercise or stay up late. The day after tooth extraction, do not do sucking action at the extraction socket to avoid the blood clot being sucked out from the socket.
