After the removal of stitches, the local tissues are not completely flattened and the extraction socket still exists, so it will show as a hole. This is because after the extraction, the local healing of the extraction socket needs a long time to be carried out, generally in about three weeks, the local soft tissues can basically grow flat and only then will it show as a hole reduction. If the local bone tissue fully recovers, it takes 3-6 months to rebuild, so a localized hole after tooth extraction is a normal performance and does not require special concern. If there are symptoms of discomfort or significant pain, you can visit the clinic again for treatment or dental radiographs.
