The soft tissue will heal in about 7 days and the patient can chew food normally without infection during this period. There will be a cavity in the extraction wound, which will take about 3 months to heal, because it takes 3 months for the alveolar bone inside to heal. The extraction wound is divided into these two categories, soft tissue healing and bone tissue healing. The extraction wound should be protected within 7 days to prevent the clot from falling off and affecting the healing of the extraction wound and the symptoms of dry socket. If infection or even severe pain occurs on the extraction wound, it is necessary to go to the stomatology department in time and contact with the attending doctor for scratching and anti-inflammatory and pain relief treatment of the wound in order to promote the healing of the extraction wound as soon as possible. Do not use any food to chew on the side of the extracted tooth within 7 days, and make sure to maintain a hygienic oral environment.
