There are usually no serious fever symptoms after tooth extraction, and even if fever symptoms occur, the prognosis is generally better for most patients after aggressive anti-inflammatory and symptomatic treatment. However, it is important to be alert to the fact that some patients may develop dry socket 2-3 days after tooth extraction and need to actively seek treatment from the dentist. Most people do not usually cause fever after tooth extraction, while a small number of people will have fever after tooth extraction, mainly related to infection caused by the large trauma of tooth extraction. If the body temperature is higher than 39℃, it is recommended to take antipyretic drugs at the same time. Generally, it can slowly return to normal in about 1 week, and at the same time, drink more water and pay attention to the maintenance of oral hygiene. If there is severe pain in the extraction socket 2-3 days after tooth extraction and it radiates to the top of the head, auriculotemporal and mandibular area, or accompanied by putrid smell and general fever, it is necessary to be alert to the occurrence of dry socket, and it is necessary to go to the hospital stomatology department for debridement treatment in time. In conclusion, if fever symptoms appear after tooth extraction, it is recommended not to worry too much. If the fever symptoms are not serious and not accompanied by other obvious discomfort, physical cooling can be given first. If the fever does not subside or even worsens, go to the hospital in time and seek treatment for the specific cause of the fever.
