Tooth extraction is a common surgical treatment in oral and maxillofacial surgery, and it usually takes 3 months for complete healing to occur after a tooth extraction. At one week after a tooth extraction, the gum tissue has initially healed, and if a gingivectomy is performed during the extraction and post-operative sutures are placed, the stitches can be removed at 7 days. At 7 days to 1 month, the bone tissue inside the gums is generally rebuilt, but at this time there is no formation of normal bone trabecular structure, and it takes 3 months for the alveolar bone to completely heal and the gum tissue to grow flat. Therefore, if you want to have your teeth restored after tooth extraction, you should wait for 3 months.
