Dear Sir/Madam!
For 5 weeks I have had a temperature somewhere around 37.5. Six months ago I had a metal post placed in an upper first premolar and a crown placed on it; that tooth had been treated. I have already been to a doctor and my blood tests are good. I would like to know whether the tooth — bacteria — could be the cause of my problems? Would I then have to have elevated leukocytes?
Thank you for your answer and kind regards,

Dear Sir/Madam!

In the case of severe acute inflammation of dental and periodontal tissues (most often periapical), systemic symptoms may occur (enlarged and painful local lymph nodes, elevated temperature, malaise...). In this case there would also be severe local symptoms (swelling, pain...), and the blood count would also change (left shift). If it is chronic periapical inflammation above a non-vital tooth (we call this a focus), the listed symptoms are not present, and the condition can only be evaluated on an X-ray.

Have a nice day!
