A wound that looks like white rotting flesh after a tooth extraction may be granulation tissue or an infection has occurred. If it is proliferating granulation tissue, no treatment is needed, and if it is caused by an infection, the wound needs to be cleared thoroughly. 1. No treatment is needed: during the healing process of tooth extraction wound, there will be granulation tissue proliferation, which will be replaced by connective tissue and bone tissue to complete the healing of the tooth extraction wound. The proliferation of granulation tissue is irregular in shape and may be white in color, which is a normal physiological phenomenon and does not require treatment. 2. Thorough debridement: after infection of the extraction wound, a grayish-white pseudomembrane may be formed on the surface, which is composed of necrotic epithelial cells and tissues, inflammatory ooze, food residues, etc. Under local anesthesia, the extraction wound should be thoroughly scrubbed and rinsed, and the infected foreign matter or granulation tissue should be removed, so as to re-establish the blood clot in the alveolar fossa. There may be other reasons why the wound looks like white rotting flesh after tooth extraction, and it is recommended to go to the hospital in time.
