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!
Also the recently deceased second forefather of biological dentistry Hal Huggins repeated and confirmed the findings of Weston Price. In his writings (Huggins Hal A, Levy Thomas (1999), Uninformed Consent: The Hidden Dangers in Dental Care, Hampton Roads Pub Co. p.278 ISBN 1-57174-117-8
.) He published together with the also in Root Cause Several times worded and famous celebrity cardiologist Thomas Levy, the dangers that can arise from dental materials and procedures.
I think it is safe to say, based on more than one hundred years of root canal treatment, that massive health problems can arise from the bacteria, endotoxins, mercaptans and thioethers, all of which are released from root-treated teeth. Thousands of biological dentists have responded (observing – recognizing – acting – proving) and implemented the knowledge gained from the observations. But what about the study situation?
Current study situation – Root Cause
For example, this brand new, international study, which is focused on Pubmed, shows that root-treated teeth clearly show carcinogenic activity (oxidative and nitrosative stress) and also contribute to depression:
Mol Neurobiol. 2018 Apr;55(4):2814-2827. doi: 10.1007/s12035-017-0545-z. Epub 2017 Apr 28. Increased Root Canal Endotoxin Levels are Associated with Chronic Apical Periodontitis, Increased Oxidative and Nitrosative Stress, Major Depression, Severity of Depression, and a Lowered Quality of Life.

Evidence indicates that major depression is accompanied by increased translocation of gut commensal Gram-negative bacteria (leaky gut) and consequent activation of oxidative and nitrosative (O&NS) pathways. This present study examined the associations among chronic apical periodontitis (CAP), root canal endotoxin levels (lipopolysaccharides, LPS), O&NS pathways, depressive symptoms, and quality of life. Measurements included advanced oxidation protein products (AOPP), nitric oxide metabolites (NOx), lipid peroxides (LOOH), -sulfhydryl (SH) groups, total radical trapping antioxidant parameter (TRAP), and paraoxonase (PON)1 activity in participants with CAP, with and without depression, as well as healthy controls (no depression, no CAP). Root canal LPS levels were positively associated with CAP, clinical depression, severity of depression (as measured with the Hamilton Depression Rating Scale (HDRS) and the Beck Depression Inventory) and O&NS biomarkers, especially NOx and TRAP. CAP-related depression was accompanied by increased levels of NOx, LOOH, AOPP, and TRAP. In CAP participants, there was a strong correlation (r = 0.734, p < 0.001) between root canal LPS and the HDRS score. There were significant and positive associations between CAP or root canal endotoxin with the vegetative and physio-somatic symptoms of the HDRS as well as a significant inverse association between root canal endotoxin and quality of life with strong effects on psychological, environmental, and social domains. It is concluded that increased root canal LPS accompanying CAP may cause depression and a lowered quality of life, which may be partly explained by activated O&NS pathways, especially NOx thereby enhancing hypernitrosylation and thus neuroprogressive processes. Dental health and „leaky teeth“ may be intimately linked to the etiology and course of depression, while significantly impacting quality of life

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.
