About 7 days after tooth extraction, the soft tissue of the extraction wound can be completely healed and you can eat normally at this time. After tooth extraction, because of the damage caused by tooth extraction, it is easy to cause bleeding, blood clot dislodgement, secondary infection, pain and swelling after tooth extraction, so there are requirements for diet. For the first 2-3 days, it is better to eat liquid food or semi-liquid food, such as milk, chicken cake, rice porridge, etc. You cannot eat food that is too hard or too hot, which will easily cause the blood clot to fall off; you cannot eat spicy and irritating food, which will easily cause secondary infection and pain after tooth extraction; you cannot eat sticky food, such as sticky bean bag, which will easily leave food residue in the operation area and cause infection; after 2-3 days, you can gradually transition to general food. After 7 days, when the tooth extraction wound is completely healed, you can eat normally.
