If the fever is only on the day of tooth extraction, it is a normal stress reaction caused by the traumatic reaction after tooth extraction, especially after the extraction of blocked wisdom teeth, which is normal and does not require too much worry or special treatment. If you have fever for 2-3 consecutive days after tooth extraction, you should be alert to the infection of the extraction socket and go to a general hospital to clarify the cause of the fever. If the infection is caused by the extraction socket, you should visit the oral and maxillofacial surgery department for timely treatment of the infection in the extraction socket and timely antibiotics to reduce inflammation. You can also go to the hospital for sedative antibiotics to achieve a rapid anti-inflammatory effect and avoid the spread of infection due to the infection of the extraction socket, which causes infection in the surrounding space.
