How long will it take for tooth infection headaches to go away?

Infection Gone!: Until all the cause of the headache is gone they will be there, so until the infection is gone and the tooth problem managed.

Depends: When the infection is successfully treated, the headaches should go away.

Should go w/infectio: Once your infection is gone, the headache should soon go away, assuming you had it treated with antibiotics, or a dentist.
