Most dentists and endodontists in the US are probably unaware of the studied and documented relationship between root-canaled teeth and degenerative disease. I’ve had numerous root canals and until recently, I was also unaware of the 25 years of research done that the American Dental Association has not been forthcoming about.


This research, which was carried out by the late Dr. Weston Price and sixty of the leading scientists of his time, is outlined in detail by Dr. George Meinig in the book Root Canal Cover-Up (Bion Publishing,1994). Ironically, Dr. Meinig was one of the original founders of the American Association of Endodontists. During his 47 years of practice, he performed countless root canals only to discover after his retirement the work of Dr. Price. Believing the dental profession would require more studies upon learning of this long-buried research, Dr. Meinig wrote Root Canal Cover-Up and began lecturing about the dangers of root canals.

The dental industry is the ONLY industry to leave a dead structure in the body. One significant finding of Dr. Price’s research was that root-canaled teeth are not sterile—and indeed could not be sterilized—even after they were extracted and submitted to sterilizing procedures. Dr Price learned that when a tooth was implanted under the skin of a rabbit, the rabbit contracted the same disease suffered by the former owner of the root-canaled tooth.

Dr. Price found that numerous types of degenerative illnesses – heart/kidney/lung/bladder and others diseases – could be easily transferred to the rabbits. Not just from implanting the whole infected tooth under their skin, but also by embedding small pieces of the root, injecting pulverized teeth (a powder), or even just the toxins from the teeth after being cultured in the lab. The other part of this experiment showed that a lot of his patients recovered from their afflictions after removing the root canal teeth. For a person who is chronically ill and has exhausted other avenues of treatment, hearing this news can provide much needed hope and direction.

If all this research about root canals is so important, you may wonder why it was covered up. Apparently, the work of Dr. Price (who was known as “the world’s greatest dentist”) was covered up because of a controversy among dentists and physicians about the validity of the “focal infection theory.” This theory was originally introduced in 1904 by Dr. Frank Billings of the Chicago University Medical School. Dr. Billings’ theory was substantiated by a monumental 1174-page, two-volume body of research produced later by Dr. Price.

Basically, the focal infection theory states that infected teeth, tonsils, sinuses, or other areas of infection hold bacteria that can travel through the bloodstream to other glands, organs, or tissues, and subsequently set up infection in the new site. In other words, infection can spread from one part of the body to another, in the same way cancer cells can spread (metastasize) via the circulating blood. Under the stresses of oxygen and nutrient deprivation, these formerly friendly organisms left in a root-canaled tooth morph into stronger, more virulent anaerobes that produce a variety of potent toxins. What were once ordinary, friendly oral bacteria mutate into highly toxic pathogens lurking in the tubules of the dead tooth, just awaiting an opportunity to spread.

Most people believe that the whole point of root canals is to remove (or prevent) infection and thus, to leave a non-offending tooth. Unfortunately, this doesn’t necessarily work. Why not? Because under the white part of the tooth (the enamel) is the dentin, which is actually comprised of about three miles of microscopic tubules.When the pulp of a tooth is removed and filled (root-canaled), the tooth no longer has the capacity to flush out the bacteria that accumulate in these tiny tubules of the dentin. To make matters worse, common X-rays are not magnified enough to reveal these tubules, much less the bacteria in them, so infection may go unnoticed in its early stages. The point is, the white part of the tooth is alive—just as bone is alive—and it needs a live nerve and artery to keep it healthy. It’s that simple.

How about these statistics:

Dr. Robert Jones, a researcher of the relationship between root canals and breast cancer, found an extremely high correlation between root canals and breast cancer. He found the following correlations in a five-year study of 300 breast cancer cases:

  • 93 percent of women with breast cancer had root canals
  • 7 percent had other oral pathology
  • Tumors, in the majority of cases, occurred on the same side of the body as the root canal(s) or other oral pathology

Dr. Jones states that toxins from the bacteria in an infected tooth or jawbone are able to inhibit the proteins that suppress tumor development. A German physician reported similar findings. Dr. Josef Issels reported that, in his 40 years of treating “terminal” cancer patients, 97 percent of his cancer patients had root canals. If these physicians are correct, the cure for cancer may be as simple as having a tooth pulled, then rebuilding your immune system.

In a continuation of Dr. Price’s work, the Toxic Element Research Foundation (TERF) used DNA analysis to examine root-canaled teeth, and they found bacterial contamination in 100 percent of the samples tested. They identified 42 different species of anaerobic bacteria in 43 root canal samples. In cavitations, 67 different bacteria were identified among the 85 samples tested, with individual samples housing between 19 to 53 types of bacteria each. The bacteria they found included the following types:

  • Capnocytophagaochracea
  • Fusobacteriumnucleatum
  • Gemellamorbillorum
  • Leptotrichiabuccalis
  • Porphyromonasgingivalis

Since When is Leaving A Dead Body Part IN Your Body a Good Idea?

There is no other medical procedure that involves allowing a dead body part to remain in your body. When your appendix dies, it’s removed. If you get frostbite or gangrene on a finger or toe, it is amputated. If a baby dies in utero, the body typically initiates a miscarriage.

Your immune system doesn’t care for dead substances, and just the presence of dead tissue can cause your system to launch an attack, which is another reason to avoid root canals—they leave behind a dead tooth.

Infection, plus the autoimmune rejection reaction, causes more bacteria to collect around the dead tissue. In the case of a root canal, bacteria are given the opportunity to flush into your blood stream every time you bite down.
