Generally, about 1 week after wisdom tooth extraction, the extraction sockets can be replaced by soft tissues and heal initially. The wound healing process after wisdom tooth extraction is as follows: the blood clot is formed within 15-30 minutes after extraction to protect the wound; the blood clot is mechanized and gradually replaced by granulation tissue after 24 hours, and the wound healing standard is basically reached in about 1 week, and most of the pain and swelling will be relieved; connective tissue and epithelial tissue will gradually replace the granulation tissue in 3-4 days after extraction, and the replacement is usually complete in about 20 days; fiber-like bone replaces connective tissue in about 1 month; immature bone tissue is completely formed in about 3 months, and the alveolar bone and mucosa are completely replaced. The fibrous bone replaces the connective tissue in about 1 month; immature bone tissue is formed completely in about 3 months, and the changes of alveolar bone and mucosa tend to be stable; normal bone tissue is formed completely in about 6 months, and the bone reconstruction process is basically completed. It is recommended not to brush and rinse your mouth for 24 hours after tooth extraction, not to eat excessively hot or spicy stimulating food, and not to lick or sip the tooth extraction wound to prevent the blood clot from falling off or infection, which will affect the normal healing of the wound.
