The mucosal wounds generally heal in 5-7 days after tooth extraction, and it takes about 3-6 months for the jawbone to reach a stable state, with slight variations depending on individual circumstances. Tooth extraction is one of the most commonly used treatment techniques in dentistry, but it can also cause local tissue damage. Usually a blood clot forms inside the wound after 30 minutes of extraction, and the clot starts to mechanize around 1 day. Therefore, care needs to be taken to avoid brushing and rinsing for 24 hours after tooth extraction to prevent infection or bleeding due to the dislodging of the blood clot in the socket. If there is no serious infection or trauma, the mucosal wound will basically heal in about 5-7 days, and the alveolar bone will start to be modified at this time. Two-thirds of the extraction socket will be filled with fiber-like bone in about 38 days after extraction, and it will take about 3 months before the socket is completely formed with less dense bone tissue. After 3-6 months of tooth extraction, the alveolar bone can be rebuilt and normal bone structure can appear, when the jaw bone reaches a more stable state and the extraction wound is fully recovered. Therefore, doctors generally recommend 3 months after tooth extraction before restoring the denture. It is also necessary to eat a warm and cool diet within 5 days after tooth extraction to avoid bleeding from the wound caused by overheated food. In case of bleeding from the dilated capillaries of the wound, local bleeding and swelling can be reduced by applying ice packs to facilitate the recovery of the wound.
