Hi sir...
Yes , dental infection may also be one of the reason for raised ESR.....it may increase by tooth decay and gum infection and swelling(abscess formation) associated with decayed tooth...
Next Steps
Immediately visit your nearby dentists for furthur opinion and take X_ray (IOPA) of that decayed tooth and get the treatment done for that tooth... then your ESR can also be decreased.....
Health Tips
Do Not take self medications.....
