Spicy and stimulating food, too hard food and too hot food are usually not suitable after tooth extraction, as follows. 1. Spicy and stimulating foods: including ginger, chili, peppers, onions, scallions, etc., which may cause irritation to the tooth extraction wound, resulting in its inability to heal properly. 2. Hard foods: such as biscuits, nuts, apples, etc., which may cause trauma to the extraction site during the chewing process, resulting in cracking, bleeding, pain and other symptoms. 3. Excessively hot food: Foods that are too hot may lead to increased local blood circulation, affecting the formation of blood clots, thus affecting the normal healing of the wound. If there are symptoms such as infection or cracking of the tooth extraction wound, it is recommended to go to the hospital in time to receive early formal treatment.
