It takes about 3 months for the extraction of the first tooth, also known as wisdom tooth extraction, to return to normal. The recovery process after tooth extraction requires the following stages: firstly, one week after the extraction, during which the doctor’s instructions should be strictly followed, so that the blood clot coagulates as soon as possible, and mechanization occurs, forming granulation tissue. After a week, the granulation tissue is basically formed and the mucous membrane above the gums is basically healed, and if stitches are needed, the stitches can be removed in about 7 days. At 1-2 months, the clot slowly transforms from granulation to bone, but the bone trabeculae are not particularly well aligned, they are sparse and not completely aligned, but they are initially formed in size. At 3 months, the trabecular structure reaches a stable state, and the alveolar bone resorption and regeneration reaches a balance, allowing the extraction wound to heal completely.
