MJ Is everyone who has ever had a root canal filled made ill by it?
G Meinig: No. We believe now that every root canal filling does leak and bacteria do invade the structure. But the variable factor is the strength of the person's immune system. Some healthy people are able to control the germs that escape from their teeth into other areas of the body. We think this happens because their immune system lymphocytes (white blood cells) and other disease fighters aren't constantly compromised by other ailments. In other words, they are able to prevent those new colonies from taking hold in other tissues throughout the body. But over time, most people with root filled teeth do seem to develop some kinds of systemic symptoms they didn't have before.
MJ It's really difficult to grasp that bacteria are imbedded deep in the structure of seemingly-hard, solid looking teeth.
G Meinig: I know. Physicians and dentists have that same problem, too. You really have to visualize the tooth structure - all of those microscopic tubules running through the dentin. In a healthy tooth, those tubules transport a fluid that carries nourishment to the inside. For perspective, if the tubules of a front single-root tooth, were stretched out on the ground they'd stretch for three miles!
A root filled tooth no longer has any fluid circulating through it, but the maze of tubules remains. The anaerobic bacteria that live there seem remarkably safe from antibiotics. The bacteria can migrate out into surrounding tissue where they can "hitch hike" to other locations in the body via the bloodstream. The new location can be any organ or gland or tissue, and the new colony will be the next focus of infection in a body plagued by recurrent or chronic infections.
All of the "building up" done to try to enhance the patient's ability to fight infections - to strengthen their immune system - is only a holding action. Many patients won't be well until the source of infection - the root canal tooth - is removed.
G Meinig: The only scientific way to prevent tooth decay is through diet and nutrition. Dr. Ralph Steinman did some outstanding, landmark research at Loma Linda University. He injected a glucose solution into mice - into their bodies, so the glucose didn't even touch their teeth. Then he observed the teeth for any changes. What he found was truly astonishing. The glucose reversed the normal flow of fluid in the dentin tubules, resulting in all of the test animals developing severe tooth decay! Dr. Steinman demonstrated dramatically what I said a minute ago: Dental caries reflect systemic illness.
Let's take a closer look to see how this might happen. Once a tooth gets infected and the cavity gets into the nerve and blood vessels, bacteria find their way into those tiny tubules of the dentin. Then no matter what we do by way of treatment, we're never going to completely eradicate the bacteria hiding in the miles of tubules. In time the bacteria can migrate through lateral canals into the surrounding bony socket that supports the tooth. Now the host not only has a cavity in a tooth, plus an underlying infection of supporting tissue to deal with, but the bacteria also exude potent systemic toxins. These toxins circulate throughout the body triggering activity by the immune system - and probably causing the host to feel less well. This host response can vary from just dragging around and feeling less energetic, to overt illness - of almost any kind. Certainly, such a person will be more vulnerable to whatever "bugs" are going around, because his/her body is already under constant challenge and the immune system continues to be "turned on" by either the infective agent or its toxins - or both.
Dr. Price traveled all over the world doing his research on primitive peoples who still lived in their native ways. He found fourteen cultural pockets scattered all over the globe where the natives had no access to "civilization" - and ate no refined foods.
Dr. Price studied their diets carefully. He found they varied greatly, but the one thing they had in common was that they ate whole, unrefined foods. With absolutely no access to tooth brushes, floss, fluoridated water or tooth paste, the primitive peoples studied were almost 100% free of tooth decay. Further - and not unrelated - they were also almost 100% free of all the degenerative diseases we suffer - problems with the heart, lungs, kidneys, liver, joints, skin (allergies), and the whole gamut of illnesses that plague Mankind. No one food proved to be magic as a preventive food. I believe we can thrive best by eating a wide variety of whole foods.
MJ Amazing. So by "diet and nutrition" for oral (and total) health you meant eating a pretty basic diet of whole foods?
G Meinig: Exactly. And no sugar or white flour. These are (and always have been) the first culprits. Tragically, when the primitives were introduced to sugar and white flour their superior level of health deteriorated rapidly. This has been demonstrated time and again. During the last sixty or more years we have added in increasing amounts, highly refined and fabricated cereals and boxed mixes of all kinds, soft drinks, refined vegetable oils and a whole host of other foodless "foods". It is also during those same years that we as a nation have installed more and more root canal fillings - and degenerative diseases have become rampant. I believe - and Dr. Price certainly proved to my satisfaction - that these simultaneous factors are NOT coincidences.
