I keep getting infections that don't go away until the affected tooth is either pulled or has a root canal. We've tried antibiotics alone with no success, not until the tooth is fixed. The thing is that xrays don't show an abscess so dentists don't believe I'm sick and ignore me. This is now happening for the 4th time and I feel just as confused as ever. How is this happening? What can I do? Symptoms: I have had burning in my chest, coughing up a lot of phlegm, tired, low grade temp for a month, loose bowels started about 3 days ago, feeling even more tired and feverish. Same each time, we try antibiotics, but I never get better til the tooth is fixed. Specialist said my immune system is fine.
