About one week to ten days after the wisdom tooth extraction, the wound of the extracted tooth will gradually heal and the patient can eat and brush normally without any further interruption. One of the criteria for healing is that there is no pain and no swelling of the face in the extraction incision area, and the patient can chew on the affected side at this time. However, there is still a cavity in the extraction incision area, which takes about three months to repair and grow flat. During this period, the patient must brush the cavity gently to clean the stagnant food inside, but do not use too much force, which may cause damage to the mucosa, because the newly grown mucosa in this area is fragile. After wisdom tooth extraction, patients must undergo routine anti-inflammatory treatment. Wisdom teeth are different from ordinary teeth in that they have greater variability and more pronounced root curvature than other teeth, so extraction procedures are more complicated. Without anti-inflammatory treatment, it is likely that the swelling will not heal and infection will easily occur.
