You can eat about 2 hours after the extraction of wisdom teeth, but you need to eat warm, cool and soft food to relieve the pain of the extraction wound. It is still necessary to eat to avoid infection in the extraction site and the whole body as the body resistance decreases. Do not eat foods that are too cold, too hot or too irritating for 1 week, as this will easily cause infection in the extraction wound and complicate the dry socket syndrome. Dry socket syndrome refers to the situation that the blood clot in the extraction socket has fallen off, resulting in a relatively empty socket, and the patient will start to experience severe pain and an obvious putrid smell in the mouth about 3-4 days after the extraction.
