Tooth extraction interval, it is generally recommended that the extraction be performed at least one week after the tooth is extracted. This is because after tooth extraction, a blood clot will be formed in the extraction socket to close the wound, which can promote normal healing, and the blood clot will be mechanized and gradually replaced by granulation tissue, and this time is about 7 days, so it is not recommended to operate within 7 days to prevent the risk of infection and other risks after tooth extraction. After 7 days, tooth extraction is generally not very risky. Of course, it can be postponed for a longer period of time to wait for better local healing of the extracted tooth, but 7 days is the time for initial healing of the extracted wound, so the interval between extractions must also be more than 7 days.
