I read an article: Shocking connection: 97% of all terminal cancer patients previously had this dental procedure done. Root canal. I have had
4 rootcanals and am concerned about the validity of the information in this article.
In recent years, the claim about root canals and cancer risk has gained traction due to a 2012 article published to the website of
In the Mercola root canal article, the century-old work of
Dr. Price was a dentist and researcher who traveled the world to study the teeth, bones, and diets of native populations living without the "benefit" of modern food. Around the year 1900, Price had been treating persistent root canal infections and became suspicious that root-canaled teeth always remained infected, in spite of treatments. Then one day, he recommended to a woman, wheelchair bound for six years, to have her root canal tooth extracted, even though it appeared to be fine.
She agreed, so he extracted her tooth and then implanted it under the skin of a rabbit. The rabbit amazingly developed the same crippling arthritis as the woman and died from the infection 10 days later. But the woman, now free of the toxic tooth, immediately recovered from her arthritis and could now walk without even the assistance of a cane.
He then went on to show that many chronic degenerative diseases originate from root-filled teeth — the most frequent being heart and circulatory diseases. He actually found
16 differentcausative bacterial agents for these conditions. But there were also strong correlations between root-filled teeth and diseases of the joints, brain and nervous system. Dr. Pricewent on to write two groundbreaking books in 1922 detailing his research into the link between dental pathology and chronic illness. Unfortunately, his work was deliberately buried for 70 years,until finally one endodontist named George Meinig recognized the importance of Price's work and sought to expose the truth.
By the time Price died in 1948, the "focal infection theory" he had researched decades earlier had already begun to fall out of favor among medical professionals. By the 1950s it was considered to be an outdated fringe belief, and endodontic research in the half century since then has turned up no evidence to support a causal link between root canals and cancer.
However, the myth of
The truth: There is no valid, scientific evidence linking root
canal-treatedteeth and disease elsewhere in the body. A root canal is a safe and effective procedure. When a severe infection in a tooth requires endodontic treatment, that treatment is designed to eliminate bacteria from the infected root canal, prevent reinfection of the tooth and save the natural tooth.
While the viral claim suggests modern endodontics practitioners "buried" Price's research, in actuality the American Association of Endodontists (AAE) addressed his findings directly and detailed why they did not stand up to basic modern standards in research:
But what about Dr. Price? This is a good example of how the Internet can give new life to
long-dispelledtheories. Believe it or not, the misinformation about roots canals that is found on the Internet is still based on Dr. Price's century-old, discredited research. Dr. Price'sresearch techniques were criticized at the time they were published, and by the early 1930s, a number of well-designedstudies using more modern research techniques discredited his findings. In 1951, the Journal of the American Dental Association took the extraordinary step of publishing a special edition reviewing the scientific literature and shifted the standard of practice back to endodontic treatment for teeth with non-vitalpulp in instances where the tooth could be saved. The JADA reviewed Dr. Price's research techniques from the 1920s and noted that they lacked many aspects of modern scientific research, including absence of proper control groups and induction of excessive doses of bacteria.
The "97 percent" figure commonly cited in the root canal cancer link claim is typically attributed to Dr. Josef Issels, a German physician who allegedly reported that "in his 40 years of treating 'terminal' cancer patients, 97 percent of his cancer patients had root canals." Of course, it's quite likely that 97 percent of Dr. Issels' cancer patients had also consumed marshmallows at some point, but in the absence of any documented causative factor, that statement demonstrates nothing more than a spurious correlation. And Dr. Issels was a promoter of alternative cancer therapy regimens who was charged with manslaughter in 1961 after three cancer patients died while under his care.
In fact, the AAE noted that research published in 2013 concluded that individuals who underwent multiple endodontic treatments actually experienced a
