I agree with most of what you've said. I've seen the tooth meridian chart before but I don't know how scientific it is. There is definitely some relationship to the infected tooth and symptoms/infected organ. For example your upper teeth basically sit at the floor of the maxillary sinus. So if you have problems with your upper teeth you are far more likely to get sinus or even brain tumors. Lower jaw due to the way the lymphatic system runs you are more likely to get tonsil and other infections. But once bacteria get into the blood stream they don't really care what tooth they came from at least with regard to your major organs.
