root-canal-procedure(NaturalHealth365) “The discovery of truth is prevented more effectively, not by the false appearance things present and which mislead into error, not directly by weakness of the reasoning powers, but by preconceived opinion, by prejudice.” – Arthur Schopenhauer

How do we decide what is correct and what is false in medicine and dentistry? In other words, how do we decide who or what to believe when it comes to healthcare, integrative or Western medicine? With so many opposing points of view on the same health topic how do we know which one to believe?

If you are more inclined to prefer a more natural approach to medicine does that mean discarding everything that allopathic medicine has to offer? Conversely, if one chooses to follow a predominately mainstream medicine approach, then should all natural alternatives be discarded as useless? Naturally, the answer is, ‘of course not.’ There are good and bad in both camps. But how do you distinguish the good from the bad – the correct from incorrect?

How to protect your health by using ‘first principles’

You do this by first distilling any conclusion down to the fundamental principles upon which the conclusion is based and reason up from there.

When either accepting or challenging current belief systems, it is imperative that all reasoning and conclusions be drawn from the level of established science, and not on assumptions, preconceived prejudices, or analogy. This is the concept of first principles. Fundamental truths upon which any hypothesis or theory is based must conform to both rational consistency and empirical observation. Any deviation from these principles will often lead to false conclusions.


If any of the parameters upon which a theory is based fails to conform to both rational consistency and empirical observation, then this theory must be discarded as incorrect.

So what does that mean? It means that all conclusions must be first based on rational consistency of what can be possible as defined by the accepted laws of physics, chemistry and biology. That doesn’t mean that it is possible, only that it can be possible. Is it rational? Can it happen? If so, then the first condition of establishing correctness is satisfied. If not, then we can immediately dismiss it as incorrect.

Finding the truth with the help of dinosaurs

Let’s say there is a claim that dinosaurs are currently living on the moon. Does this satisfy rational consistency? The answer is obvious, no.

First of all, dinosaurs are extinct. In addition, we know that the moon has no air, so supporting a living creature dependent on respiration such as a dinosaur would be impossible. We can stop right there because this claim does not meet the requirement of rational consistency. We do not need any further evidence.

But, what if someone claimed that there are huge cities built on the moon with thousands of people living there. Could this be true? Well, of course that is highly unlikely, but it could be true. We do have the technology to do this. Although highly unlikely, it could be possible.

So how do we find out if this is true or not? We look for empirical evidence. We make observations. There are telescopes that can examine the surface of the moon facing us. There are spacecraft orbiting the moon with cameras that can easily spot a city on the moon. We can directly look and see if there are cities on the moon or not. If there are none, then the claim is false.

So first principles accepts that statements made about reality must conform to the properties of reality which are:

1. Rational consistency: If it is rational it might be true. It does not mean that it is true, only that it could be.

2. Empirical evidence: If both empirically valid and rationally consistent, then it is true.

Applying first principles to a root canal procedure and risk analysis

So how do we apply this to our analysis of the risks involved with root canal-treated teeth?

Currently accepted beliefs and accepted truths, such as the American Association of Endodontists (Dentists who specialize in performing root canals) assertion that root canal teeth cannot cause or contribute to systemic disease and do not leak bacteria and toxins systemically, must be distilled to the first principles upon which this claim is based.

We first must define all of the properties of root canal teeth. Then, we can ask the question on how these objective properties of root canal teeth relate to known biological and physical principles. We continue the analysis from the ground up until we reach a logical conclusion. Then, we test this conclusion with direct observation.

Let’s look at the role of root canal teeth and heart disease. It has been established that a main driving factor in cardiovascular disease and heart attack is inflammation and the resulting damage to the lining of the coronary artery (endothelium). We know that infection and bacterial toxins are one source of this inflammation and endothelial damage. But, how does a root canal contribute to cardiovascular disease?

It is established that all root canals remain infected and become more infected over time. The American Dental Association has acknowledged this. It is also true that these bacteria produce potent exotoxins. Dr. Boyd Haley has demonstrated the presence of potent toxins leaching directly out from the root canal tooth root.

The untold truth about a root canal procedure

The American Association of Endodontists states that toxins are not released from root canal teeth. It claims that both bacteria and toxins that are inside the tooth remain “entombed” within the tooth and that they do not travel systemically to other sites in the body. And if bacteria do make their way out of a root canal tooth this organization further asserts that the infection will remain local and not travel to distant sites in the body.

Are these statements both rationally consistent and supported by empirical evidence?

Bacteria within root canal teeth produce many varieties of small molecule toxins. Can these toxins escape from inside the tooth? As mentioned above, Dr. Haley has tested root canal teeth for toxin release and found that root canal teeth do indeed release very potent toxins. These molecules are very small and make their way out of the tooth root.

In addition, biopsies have shown that a large percentage of root canal teeth do not have a complete seal within the canal. Remember, these toxins are very, very small molecules. They can easily diffuse out through the root surface and also out the apex of the tooth root. They cannot be “entombed” inside the tooth.

If it doesn’t make rational sense, and contradicts observation, it must be false

The statement by the American Association of Endodontists does not satisfy rational consistency or empirical evidence. So it must be false.

The truth is that bacterial toxins do leach out of root canal teeth. Small molecules cannot be contained inside an imperfectly sealed root canal or porous root surface. This is not rationally consistent. Empirical evidence from the research of Dr. Haley has confirmed the release of these toxins. Once they are released there is nothing to stop them from traveling to other sites in the body.

Now what about the bacteria themselves? Remember the ADA claims that the bacteria remain “entombed” within a completed root canal. Is this true?

Virtually 100% of the bone around the bottom of the tooth socket after extraction of a root canal tooth was shown to be infected with bacteria. I can’t remember a single case where I obtained a negative bacterial culture from the bone surrounding a root canal–treated tooth.

The American Association of Endodontists says that even if bacteria leak out of a root canal tooth they will remain in the tissues immediately adjacent to the tooth and will not travel to distant sites of the body. They further state that the immune system will destroy any bacteria that get into the bloodstream before it can be seeded to another body part.

Both statements are incorrect. It has been established that pathogenic bacteria within root canal teeth can “disarm” the immune system through a variety of mechanisms and may not be destroyed. It has also been proven through DNA analysis that the same bacteria from root canal teeth are found in the plaques of coronary arteries and in the blood clots that have caused a heart attack. These bacteria traveled from a root canal tooth to the coronary arteries of the heart.

Will Western medicine ever face the simple truth about a root canal procedure?

We have established that:

1. All root canal teeth remain infected and become more infected over time.

2. Pathogenic bacteria inside the root canal-treated tooth produce potent exotoxins that leak out of the tooth and travel systemically.

3. Bacteria inside the root canal tooth leak out of the tooth into the adjacent bone and can travel to distant sites of the body.

4. The immune system does not always eliminate these pathogenic bacteria.

5. Bacteria from root canal-treated teeth have been found in distant sites of the body such as coronary artery plaque, pericardial fluid in coronary diseases patients, and in ruptured cerebral aneurysms. This has been positively confirmed by documenting the presence of the DNA unique to root canal pathogens at these sites.

By using first principles analysis, we can conclude that root canal teeth do spread both bacteria and bacteria-produced exotoxins systemically throughout the body, and that these toxins and bacteria may cause or contribute to a variety of systemic diseases.

1. Pessi, Bacterial Signatures in Thrombus Aspirates of Patients with Myocardial Infarction. Journal: Circulation. February, 2013

Conclusion: Dental infections and oral bacteria, especially viridens streptococci, may be associated with the development of acute coronary thrombosis.

Bacterial DNA typical for endodontic infection, mainly oral Viridans streptococci, was measured in 78.2% of thrombi, and periodontal pathogens were measured in 34.7%.

2. Caplan, The Relationship between self-reported history of endodontic therapy and coronary heart disease in the Atherosclerosis Risk in Communities Study. J. American Dental Association. August, 2009

Conclusion: Among participants with 25 or more teeth, those with greater self-reported history of endodontic therapy were more likely to have cardiovascular disease than were those reporting no history of Root canal therapy.

Corrected for other risk factors such as smoking, obesity, high cholesterol, People with root canal treated teeth had two or more times the risk of prevalent cardiovascular disease than those with no history of root canals.

3. Louhelainen, Oral Bacterial DNA findings in pericardial Fluid. Journal of Oral Microbiology, Nov. 2014

Conclusion: Oral bacterial DNA was detectable in pericardial fluid and an association between the severity of Coronary Artery Disease and the total amount of bacterial DNA in pericardial fluid was fund, suggesting that this kind of measurement might be useful for clinical purposes.

Of 22 cases, 63.6% were positive for endodontic bacteria and 36.4% for periodontal disease associated bacteria.

4. Pyysalo, Journal Neorology Neurosurgery Psychiatry, Nov. 2013. “The Connection Between ruptured Cerebral Aneurysms and Odontogenic Infection.”

Conclusion: This is the first report showing evidence that dental infection could be a part of pathophysology in intracranial aneurysm disease.

Bacterial DNA was detected in 58% of specimens. One third of the positive specimens contained bacteria form both endodontic and periodontial bacteria. DNA form endodontic bacteria was detected is 56% of the positive samples and 47% from periodontal bacteria.

    This is one of the most misunderstood procedures. First and foremost the public doesn’t have the slightest idea of what it means to have this procedure done. The first thing they think is the tooth is being saved.

    The misconception is that they get to keep the tooth and it looks fine. I never had a dentist tell me anything other then I needed a root canal. There was no informative information given.

    No red flags went off, I was glad the tooth didn’t need to be pulled. Root canals are routine, so needing a few more over the years was fine as long as it looked good and worked.

    What I should have realized is non-holistic dentists come out of the same world as other medical professionals such as doctors. This means slash, cut and burn is the way to go.They have the same mentality and thus do present a clear and present danger to the public.

  • Sam Jarret

    I believe that we really should not wait for the final word on this information. Having grown up in the time when every filling was silver colored, they were not labeled as mercury fillings, I know how long it takes the word to get out.

    I had a mouthful of silver fillings removed by a mainstream dentist who used none of the now known precautions. This profession is much too slow to take any steps to change, we need to avoid the need for their services.

    If we can’t then look for a holistic well trained dentist who understands the dangers of root canals.

    • Craigson Burg

      Haven’t found one yet who admits root canal dangers. Ive visited 4 biological and or holistic labeled dentists. How is your health btw as that was alot of mercury you were exposed to I imagine. Ive had 1 big amalgam drilled out with no precautions. My health is not horrible but its not the greatest for a 34 year old either as I should be in top form of my life right now.

  • Caryle F

    Who is America doesn’t have at least one root canal. This is a big problem and the only way to stop this procedure from continuing is to put out this information.

  • Barbara

    But, then what is our alternative? It is not stated here!!!

    • Wendy Allen

      Zirconium implant or bridge maybe instead.

      • Craigson Burg

        I had a dentist tell me zirconium hasn’t been studied enough and has high risk of breaking. Have you heard otherwise?

        • Wendy Allen

          Hi, It is suppose to be hard and not interact with tissues as much as Ti which may poison people if they get enough of it. I would guess it could break. I don’t know anyone who has had that trouble, but no implant maybe perfect. Getting a root canal out a person needs to have no herbals supplements or supplements that may thin blood like ginkgo/garlic/Vit E etc. for two weeks before which I can’t do.

      Once the pulp tissue inside the tooth has become infected or has died, the only two options are root canal or extraction of the tooth. Restorative options to replace a missing tooth (teeth) include: a removable partial denture, a fixed bridge, or a dental implant. After being informed of the risks of a root canal, as well as the risks and limitations of other restorative options, you may still decide to have a root canal. Nothing is risk free. The key is informed consent, so that you can make the treatment decision that is right for you. Dr. Levy and I discuss this in detail in our book, The Toxic Tooth.

    • Albert Fabiano

      To me there is one really good alternative-do everything to keep healthy, Somehow the mouth, gums and teeth seem to be thought of as separate.

      I personally never realized how integral the health of my mouth was. When I went to the dentist I thought this had nothing to do with everything I went to the doctor for.

      I did try to take care and did worry about other parts and systems, while not thinking much about the dental work being done. It was like there was a disconnect.

      Once there is a problem the best you can do is find the best holistic dentist. From what I researched there are people that reversed dental problems thought diet and care. Even if you do go to a holistic dentist it will still be up to you to change the climate in your mouth for the better.

      • R.Kulacz,DDS

        Hi Albert.
        You are right on target. The mouth is an integral part of the body.

        Some dental problems such as periodontal disease can be treated and the infection controlled. Teeth with reversible pulpits can sometimes be treated and a root canal prevented. However, once the pulp tissue inside the tooth has died, it is dead. Dead is dead.

        No treatment can bring a dead pulp inside the tooth back to life. The infection within the root canal system cannot be eliminated by any method including ozone. In fact, the tooth will become more infected over time. Nothing can prevent this from happening.

        Whether a root canal tooth causes or contributes to a systemic disease in an individual is dependent upon a host of factors such as genetics, host immune system response, type of bacteria within the root canal tooth, etc.

        • Craigson Burg

          your last paragraph just really points out how bad a chronic disease your going to be dealing with. The tooth is still going to do its best job at causing systemic disease all the other factors will just “help” reduce how bad your health is.

    Excellent article. Thank you for publishing it.

    My mother was a dental assistant for a dentist for a few years before she got married at age 21. As a wedding gift the dentist said he would give my mother the best gift possible that would help her for the rest of her life and save her a lot of money. He extracted all her teeth except the six top and bottom front teeth and gave her false teeth. She lived almost another 70 years and told me that having her teeth out was the best thing she did and only needed to visit a dentist occasionally to slightly adjust the false teeth. No root canals or any other expensive procedures.

    • Craigson Burg

      seems a bit extreme there but compared to root canals a better option. so never had implants I take it?

      • Marco

        I don’t think they had implants in 1938 but I could be wrong. That said I have a friend who got the hell in with always having fillings and root canals that he had all his teeth taken out about 20 years ago. Said it was the best decision he ever made.

        • Craigson Burg

          I’m at a decision making point in my life as Ive had 4 root canals and numerous fillings and 5 crowns. (grew up on the SAD if it wasn’t obvious) So unless growing teeth becomes a reality im stuck with costly implants that may or may not break (if I go with zirconia)

  • Wendy Allen

    No gluten/dairy/soy/sugar/GMO…vitamins/good oils, LDN to block hidden gluten and detoxing may help teeth and prevent cavities. Green tea may help heal teeth and more from natural dentists…see internet. Oil pulling may help prevent cavities/brush/floss eat food that doesn’t hurt/easy to clean teeth.. like carrots etc. Zirconium implant or bridge maybe instead of root canal may help. Best wishes.

  • Josh V

    I had a lot of dental work since childhood. The one fact that showed me the disconnect of the dentists I saw was the way they blamed my problems on genetics. I was told a diet high in sugar had nothing to do with it.

    The proof they said was they have patients who eat sugary foods and have no problems. Some people can be more prone to certain conditions though genetics, but they have to turn the condition on.

    This is a known fact. I know that dental schools are part of the medical thinking that is setting the standard of care. That is the approach which means robotic trained health care in America including dental practices treat people.

  • EarthPulseTech

    experiences with several close friends suggests you can kill the infection in the root and surrounding bone matrix using very strong pulsed electromagnetic fields. a bob beck strong pulser does a decent job but a 20,000 gauss suitcase type would tend to do it better. needs follow up treatments to be sure bacterial lifecycle is cut.

    • Craigson Burg

      and what about emf side effects that this will cause?
