Most people are walking around with infections in their jaws. Quite common from extracted wisdom teeth where the bone never fully heals, or where people have had root canal teeth and the bone around them eventually starts to die off. Quite often there will be an abscess at the bottom. Personally I think dental/jaw bone infections are probably one of the main drivers for CFS in people. It's why I was sick for nearly a decade, and how I got better.
