My husband has been running a fever 100-102 for 3 weeks now. We have thought it was his teeth (which need pulling) buthe has been on penicillin for a week now and no change. Does anyone know the symptoms of infected gum and teeth poisoning. He is weak & tired, lost 35 lbs in a few months, no appetite, nauseus, headache, arthritic like pain, pain around his body where the bottom of rib cage is. Teeth and gums have been painful for a long time. Dentist won't work on his mouth until fever is gone. Has anyone had dental poisoning that can describe symptoms?
