Is it normal to have a fever of 38°C after wisdom tooth extraction?

It is normal to have a fever of 38°C after wisdom tooth extraction. Generally, tooth extraction does not cause high fever; it may lead to low-grade fever, which should gradually improve. Wisdom tooth removal, like other surgeries, is an invasive procedure. Especially when the trauma is significant—such as when incisions or bone removal are required—it is still considered normal to experience a mild fever, for example between 37.5–38°C. This can usually be well controlled through physical cooling methods such as local cold or ice compresses applied to the extraction site. The fever should gradually subside by the second day after the procedure.

If the fever persists for a prolonged time, especially if body temperature exceeds 38.5°C, prompt medical consultation is necessary to rule out local wound infection or accompanying systemic conditions such as the common cold. Be vigilant for the possibility of other concurrent illnesses, so as not to delay their diagnosis and treatment. If the fever responds well to medication, such as antibiotics, observation at home may be acceptable. However, if the fever remains uncontrolled over time, timely hospital visit is essential to avoid missing or delaying treatment for other potential diseases.

Avoid brushing teeth or rinsing the mouth within 24 hours after tooth extraction, and do not disturb the blood clot in the socket. Eating should only begin after the anesthetic has worn off. After extraction, consume only lukewarm or cool soft foods during meals. Avoid hot, hard, spicy, or irritating foods. It is generally recommended to avoid alcohol and smoking, and refrain from strenuous physical activity to prevent infection and complications such as limited mouth opening.
