Post-Tooth Extraction: Temperature Readings - Dentistry

More Info

---

After a tooth extraction, it's not uncommon to experience some changes in body temperature, and understanding how to accurately measure your temperature is important for monitoring your recovery.
When it comes to measuring temperature, different methods can yield slightly different results. The three common methods are oral (mouth), axillary (armpit), and tympanic (ear). Each method has its own normal range and accuracy levels.
1. Oral Temperature: This method is generally considered reliable and reflects the core body temperature. The normal range for oral temperature is typically around 36.1°C to 37.2°C (97°F to 99°F). If you are measuring 37.8°C (100°F), it indicates a mild fever, which can be a normal response to surgery and healing.

2. Axillary Temperature: Measuring temperature under the armpit is less accurate than oral or tympanic methods. The normal range for axillary temperature is usually about 0.5°C to 1°C lower than oral temperature. Therefore, if your oral temperature is 37.8°C, your axillary temperature might be around 36.8°C to 37.3°C, which is still within the normal range.

3. Tympanic Temperature: Ear temperature readings can be influenced by external factors, such as earwax or the position of the thermometer in the ear canal. The normal range for tympanic temperature is similar to oral temperature, but it can vary based on the technique used.
Given that you had a tooth extraction three days ago, a temperature of 37.8°C is not unusual. After surgical procedures, it’s common for the body to react with a slight increase in temperature as part of the healing process. This is often due to inflammation and the body’s immune response to the surgical trauma.
However, it’s important to monitor your symptoms closely. If your temperature continues to rise above 38.3°C (101°F), or if you experience other symptoms such as increased pain, swelling, or discharge from the extraction site, it may indicate an infection or other complications that require medical attention.

In summary, measuring your temperature using oral or tympanic methods is generally more accurate than axillary measurements. A reading of 37.8°C after a tooth extraction is likely a normal response to the procedure. However, keep an eye on your symptoms, and if you have any concerns about your recovery, don’t hesitate to reach out to your dentist or healthcare provider for further evaluation. They can provide guidance tailored to your specific situation and ensure that your recovery is on track.
