The main treatments for tooth extraction wound infection are pus drainage, debridement, and use of antimicrobial drugs. 1. If the extraction wound is purulent, the main treatment is local treatment, such as pus drainage and debridement of the extraction socket. The infected foci of the extraction wound can be incised and drained, locally irrigated, and then the inflammatory tissues of the alveolar fossa can be scratched and debrided. 2. If the infection of the extraction wound is accompanied by generalized fever and discomfort, antibacterial drugs, such as amoxicillin and metronidazole, can also be used.
