Tooth extraction is not recommended for patients with cirrhosis. Cirrhosis may be caused by viral hepatitis, alcoholic liver disease, drug-induced hepatitis, steatohepatitis, etc. It is characterized by fibrosis of liver tissue and pseudo lobe formation. Changes in liver structure lead to decreased liver function, and symptoms such as fatigue, loss of appetite, nausea, vomiting, abdominal distension, and diarrhea are possible. Cirrhosis may also result in bleeding tendency or symptoms such as vomiting blood or nosebleeds due to a decrease in clotting substances such as prothrombin synthesized by the liver. Cirrhosis of the liver has an effect on the coagulation function. When extracting teeth, due to the decrease in coagulation function, there is a possibility of increased bleeding and coagulation disorders, so extracting teeth is not recommended for patients with cirrhosis.
