Weston Price was no less than the chairman of the research department of the American Dental Association and showed in his studies that his patients were not only healthier and symptom-free after the removal of the root-treated teeth, but also that over 80% of the sheeps and rabbits, into which he implanted these root-treated teeth developed the same symptoms as the donors!

Background: This study compares the radiographic distribution of apical periodontitis (AP) in rootfilled and endodontically treated teeth among healthy controls and patients with systemic diseases; the incidence of AP was almost twice as high in the latter group.
Objective: The question arises as to whether the biogenic amines (mercaptan/thioether/hydrogen sulfide) originating from endodontically treated teeth have systemic, subtoxic and immunological effects. Method: In order to determine this, local hydrogen sulfide measurements of endodontically treated teeth were combined with the laboratory serum analyses of modified proteins to assess the relationship of these compounds with type IV immune reactions.
Results: It was found that 42.5% of the group with systemic diseases showed immunological disturbance as a result of root-filled teeth. Furthermore, the presence of AP was almost three times higher than in the control group (17.2% versus 5.9%, respectively).
Conclusion: In summary, the data demonstrates that local pathologies caused by endodontically treated teeth may increase immunological and systemic dysfunction.
Further studies on root cause
In fact, there are hundreds of studies that confirm the statements, which were stated in “Root Cause” – whereas we do not know of a medical study that unequivocally proves that the root-treated teeth have no impact on patient’s health.

More information about the dangers of root-treated teeth / root cause and the technical limitations can be found here.
Since the risk to the patient’s health when leaving root-treated teeth is certainly greater and more severe than the removal, we see a “reversal of the burden of proof” among advocates of endodontology, and urge them to submit or initiate appropriate studies that will address and prove the alleged intactness of the organism after a root canal treatment.
