For various reasons, some patients have wound infection after tooth extraction. What should I do? Let's listen to the opinions of the dental experts of Liang Ya's Department of Stomatology and Plastic Surgery in Beijing. Liang Ya, a dental expert, said that infections after tooth extraction generally include alveolar fossa infection and periodontal infection. Communicate with experts according to symptoms, click on consultation, and get healthy and beautiful teeth. Dental experts in Liang Ya Stomatology said that alveolar fossa infection can come from the primary infection of the tissues around the root tips of teeth; It can also be because the tooth extraction operation takes too long, the alveolar fossa lacks the protection of blood clots after operation, and bacteria in the oral cavity enter the alveolar fossa to form infection; A few cases may be caused by poor disinfection during tooth extraction. Alveolar fossa infection usually occurs within a few days after tooth extraction. Poor healing of alveolar fossa, no blood clot in the fossa, severe pain and rancid smell, called dry socket disease, is actually local osteitis of alveolar fossa. The treatment method is: gently remove the necrotic tissue in the alveolar fossa, then add antibiotic powder with zinc oxide powder, make paste with clove oil, and fill it in the alveolar fossa, which can relieve pain and promote the rapid growth of new granulation tissue. Another kind of infection is: periodontal infection refers to the infection of soft tissue around jaw after tooth extraction. Infection can spread to the submandibular and other places. Patients often have systemic symptoms such as chills and fever. Periodontal infection may come from the infection spread of the diseased teeth themselves; Or secondary infection caused by bleeding after tooth extraction, or it can be caused by bacteria brought into deep tissue by the injection needle tip when injecting anesthetic. Treatment: When these infections are found, they should be treated with antibiotics immediately. If an abscess has formed, it should be cut and drained. If systemic symptoms are obvious, supportive therapy such as infusion should be used at the same time. Dental experts in Liang Ya reminded that in order to avoid infection symptoms after tooth extraction, patients are advised to choose regular dental plastic surgery and professional dentists for tooth extraction. more
