Dear Dr. Hall,
I was told by my children’s dentist that an infection in the mouth in general (gums, teeth, etc.) can’t cause a fever. Correct me if I’m wrong but I always thought it could cause a fever. Can you please let me know if it could or couldn’t cause a fever & why? They didn’t seem to want to take the time to explain.
Thank You so much for your time & your blog!
Sincerely, Roseann from New Hampshire
There must be some miscommunication. Yes, an infection in the mouth can cause a fever. An infection anywhere in the body will bring in your body defenses, and have the potential to cause a fever.
Maybe what they were trying to say is that most dental infections don’t cause any significant fever. Most of the time it doesn’t. Often, an infection is confined just within a tooth, and often the body contains the infection, keeping it so well controlled that there is no noticeable infection. So fevers aren’t usually present when there is a tooth or gum infection. But that isn’t always the case.
Actually, sometimes a tooth infection can cause a run-down feeling, also. I saw that in several patients. And a child can sometimes run a fever because of cutting teeth.
