Root canals are the most toxic most damaging procedure dentists can do. You have two options: a root canal or an extraction. Dentists usually fill root canals with gutta percha. Some use the Sargenti method, a popular treatment used by 25% of dentists, but denounced by the American Dental Association because it contains formaldehyde compounds. There have been a lot of problems with those. They used to contain lead. The current formulas are said to have removed the lead, but millions of root canal treatments using the old formulas are still in people's mouths. Gutta percha is 15% barium so that it will show up in the X-ray. Gutta percha shrinks and leaves gaps and the tooth can never be sterile. There is no such thing as a sterile root canal. During a root canal, the main canal is filled and possibly some of the small side canals, but the other smaller canal-like structures in teeth called dentinal tubules are too tiny to be filled during treatment and these tubules become home to bacteria instead. Since there are millions of these tubules there is room for enough bacteria to challenge the immune system. The waste products from these nasty germs include some very toxic substances called thio-ethers, and your body has to deal with these toxins 24 hours a day. They contaminate the bone around the tooth and they are picked up by the immune system and carried to the liver for detoxification. Unfortunately, the liver can be seriously damaged by them. Weston Price conducted research on root canals and wrote two books about how toxic they can be. So you have to make up your mind what is more important to you. I believe no tooth is worth destroying my immune system. by Jerome, Frank, D.D.S. (812) 376-8525, Columbus Indiana, Author of "Tooth Truth"

MJ You're assuming that ALL root-filled teeth harbor bacteria and/or other infective agents?

GM Yes. No matter what material or technique is used - and this is just as true today - the root filling shrinks minutely, perhaps microscopically. Further and this is key - the bulk of solid appearing teeth, called the dentin, actually consists of miles of tiny tubules. Microscopic organisms lurking in the maze of tubules simply migrate into the interior of the tooth and set up housekeeping. A filled root seems to be a favorite spot to start a new colony.

One of the things that makes this difficult to understand is that large, relatively harmless bacteria common to the mouth, change and adapt to new conditions. They shrink in size to fit the cramped quarters and even learn how to exist (and thrive!) on very little food. Those that need oxygen mutate and become able to get along without it. In the process of adaptation these formerly friendly "normal" organisms become pathogenic (capable of producing disease) and more virulent (stronger) and they produce much more potent toxins.

Today's bacteriologists are confirming the discoveries of the Price team of bacteriologists. Both isolated in root canals the same strains of streptococcus, staphylococcus and spirochetes.

MJ Is everyone who has ever had a root canal filled made ill by it?

GM 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.

GM 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.
