Is It Normal to Have a Fever After Tooth Extraction? - Dentistry

After a tooth extraction, it is not uncommon to experience some degree of swelling and a slight increase in body temperature. However, a fever, defined as a body temperature above 100.4°F (38°C), can indicate an underlying issue, such as an infection. In your case, a temperature of 37.3°C (99.1°F) is slightly elevated but not considered a fever. The slight swelling in your mouth is also a normal response to the surgical procedure, as the body reacts to the trauma of the extraction.

It's important to monitor your symptoms closely. If the swelling persists or worsens, or if you develop a fever above 100.4°F, it would be prudent to contact your dentist or oral surgeon. They may want to evaluate you for possible complications, such as dry socket or infection, which can occur after tooth extractions.
Dry socket, or alveolar osteitis, is a condition that can occur when the blood clot at the extraction site becomes dislodged or dissolves before the wound has healed. Symptoms include severe pain that typically starts a few days after the extraction, bad breath, and an unpleasant taste in the mouth. If you suspect you might have dry socket, it is essential to seek dental care promptly.

Infections can also occur post-extraction, and they may present with symptoms such as increased swelling, redness, warmth around the extraction site, pus discharge, and fever. If you experience any of these symptoms, it is crucial to seek medical attention as soon as possible.

Regarding your concern about measuring oral temperature, it is indeed less reliable than other methods, especially if there is swelling or discomfort in the mouth. If you are concerned about your temperature, using an ear thermometer or a digital thermometer under the armpit may provide a more accurate reading.

In summary, a slight increase in body temperature and some swelling after a tooth extraction can be normal. However, if you experience persistent or worsening symptoms, it is essential to consult your dentist for further evaluation. They can provide the necessary treatment to ensure proper healing and address any complications that may arise. Always remember that post-operative care is crucial for a smooth recovery, so follow any aftercare instructions provided by your dental professional.
