Postoperative infection is one of the most common complications of tooth extraction.It may manifest as lo-calized infection or develop to systemic infection.Clinically,oral surgeons can prevent postoperative infections by urg-ing patients to strengthen oral hygiene,applying antibiotics in a rational and compliant manner,and choosing appropriate surgical methods for tooth extraction.For the treatment of infection,the oral surgeon should formulate a response strate-gy on the basis of different diagnoses.For local infections such as dry socket,delayed alveolar osteitis,gap infection,and marginal osteomyelitis of the jaws,the infection can be controlled by local debridement,therapeutic use of antibiotics,and incise and drain if necessary.For patients suspected of necrotizing fasciitis,timely extensive debridement should be made to reduce the area of tissue necrosis.For those who have received radiotherapy or anti-resorptive drugs,tooth extraction should follow the recommenda-tions of the relevant clinical guidelines or expert consen-sus to minimize the risk of osteonecrosis of the jaws.For patients with poor systemic health or dysfunction of the immune system,attention should be paid to identifying infective endocarditis and intracranial infection to ensure the life safety of patients.In this study,the author intends to combine lit-erature review and clinical experience to tackle postextraction infection and its prevention to provide a reference for col-leagues on oral and maxillofacial surgery.
