Infection after tooth extraction Mild infection: 70% chance of occurrence After tooth extraction, especially wisdom tooth extraction, a little pain and slight swelling are normal and usually do not affect your image and normal study and work. Take oral anti-inflammatory and pain medication for three days, usually fenbutrazol and tinidazole. Moderate infection: 10% chance of occurrence After wisdom tooth extraction, significant facial swelling and severe pain is not an accident. As long as the pain is lighter than the day, it is usually fine. You can increase the dose of anti-inflammatory drugs or even infusion for a few days. You can rest for a day or two. If the pain is not lighter than a day or even worse after the third day, please go back to the doctor promptly. Severe infection: 3% chance of occurrence Severe swelling, severe pain and restriction of mouth opening after wisdom tooth extraction, you must call your doctor for treatment. Bleeding The bleeding will be present for 24 hours after the extraction and will stop by the next morning in 80% of cases. If the bleeding is slight, you can take Yunnan Baiyao orally (forbidden for patients with thrombosis or heart attack!). If there is a lot of bleeding, you should go back to the doctor for treatment. Nowadays, anesthetics are generally equipped with hemostatic agents, so bleeding will be less. Generally, elderly people have poorer coagulation function, and the probability of difficulty in stopping bleeding increases slightly. Broken tooth roots during tooth extraction I would like to mention this issue in particular, if your tooth has not been inflamed. If the remaining root is less than one-third of the total length of the root, it is not necessary to remove it. It is not necessary to get it out. If it is not easy to do so, don’t do it. Forcing it out is more damaging than leaving it unplugged!
