Signs & symptoms of infection after wisdom teeth extraction

Updated February 21, 2017

Extraction of the wisdom teeth usually occurs soon after they begin to erupt on the surface of the gums. Most people do not have enough room in their mouth for these teeth, and without an extraction the wisdom teeth become impacted. Infection after the procedure is one of the complications that could occur after a wisdom teeth extraction.


Pain is usual after a wisdom teeth extraction, but when it becomes more severe on the day after the surgery, it may be a sign of infection. Pain begins to diminish after the extraction procedure, but when the gums and extraction site is infected, the pain steadily increases.

Fever and Chills

Infection at the extraction site can cause a fever exceeding 37.8 degrees C, according to Patients experiencing a high fever should see a doctor immediately to treat infection. Antibiotics treat infection at the extraction site. In addition to a fever, some patients may experience chills.


The area where an extraction takes place will swell when an infection is present. After the extraction procedure, the mouth and gums will appear swollen as a normal effect of the procedure. When swelling does not diminish as the mouth heals or appears to get worse, it is an indication of an infection.

Bad Taste

Infection causes a bad taste in the mouth, which may or may not taste salty, according to Treatment for an infection of the extraction site eliminates the taste from an infection in the mouth.


A severe infection can cause a discharge from the extraction site. It is rare for an infection after a tooth removal to cause an infection that requires hospitalisation, but in some severe cases, the area may have to be drained and intravenous antibiotics administered.
