Results of The Coors Blood Chemistry Study on the Effects of Dental Mercury Amalgam Fillings and Recent Investigations into the Toxicity of Root Canals and Cavitations

Toxicity of mercury and root canals has been discussed for over a century, but the technology and political climate made it unpopular to discuss. Now the desire to care for patients is over-powering the political implications, and blinders to our vision are coming off so that we may take a closer look into these issues.

Quaksilber is the German word for mercury: a dentist who used mercury in the 1800's was called a Quak for short. Amalgam fillings cause three dangerous actions to occur:

- Electrical currents

- Toxic oxide formation

- Mercury vapor

Mercury vapor is freed by electrochemical reactions with other metals in the filling. It then enters the body through the gut, lungs and directly up nerve axons to the brain. Micro organisms in the gut convert elemental mercury to methyl mercury, an organic form of the metal, which is 1000X more potent in causing genetic damage than colchicine. It attacks the nervous system, immune system, kidneys and the intestinal functioning because it is an intracellular toxin. Methyl mercury is 100X more toxic to the nervous system than elemental mercury and passes brain and placental barriers. It is absorbed 45X faster than mercury through mucosal membranes and is retained by the body longer

Mercury fillings are a metallic hot spot of continually reacting metals which gives off a current. This current can range from -100 up to 100 microamps. Nearby is the brain which uses only 7-9 nanoamps. Mercury fillings give off 1000X more current than the brain. The new high copper amalgams introduced in the 1970's release 50X as much mercury into the body.

Pathological changes in the blood include:

- Mercury binding to oxygen receptor sites in the hemoglobin with consequent lowering of oxyhemoglobin saturation.

- Altered porphyrin synthesis with changes in elevated urinary excretion.

- Alteration in WBC and NK cell populations.

- Alteration in bilirubin, cholesterol and CPK levels.

Diseases where amalgams should be ruled out as cause of disease: MS; Porphyrias; Headaches; Dementias; Neurological diseases; Kidney diseases; Essential hypertension; Irritability; Infertility.

Symptoms indicating a need to investigate mercury toxicity.' anorexia; depression; swollen glands; insomnia; moodiness; irritability; memory loss; nausea; diarrhea; gum decay; fatigue; headaches.

Diagnosis Protocol

Hair analysis

Urinary DMPS/DMSA Challenge

Urinary Porphyrins


Chem screen

Dental exam: tattooing, number of fillings

X-rays: cavitational remnants

Galvanic testing

Mercury vapour analysis

Post Removal Treatment

- Go slow, mercury activated in the body by a change in equilibrium disturbs immune function.

- Avoid mercury sources other than amalgams.

- Consider chelation: DMPS, DMSA (2,3-dimercaptosuccinic acid), EDTA.

- Low temperature saunas.

- Multimineral supplementation.

- Glycine -- 80 mg/kg body weight between meals.

- Niacin -- 400mg & work up to 3000 mg.

- Vitamin C -- 3,000 mg and work up to 10,000 mg./day. IV the day of removal is the best, although not a true chelating agent, it is a powerful antioxidant.

- Vitamin E -- 400-800 iu/day.

- L-Glutathione (GSH) 300-600 mg/day, do not give at the same time as DMPS or DMSA but give the day before the DMPS or DMSA.

- Garlic - 1 cap three times/day.

Other Dental Materials Which Cause Health Problems

Materials implicated in immune hypersensitivity and toxicity: Nickel, Palladium and Copper

Coors Study

Recently, the Adolph Coors Foundation funded a study on patients to determine what effect placement and removal of amalgam fillings had on measurable blood chemistry values. We found that hemoglobin levels were quite responsive to the presence of amalgam, as was the measurement of actual oxygen saturation called "oxyhemoglobin." Hemoglobin and our energy source ATP are dependent upon the proper metabolism of porphyrins, and porphyrin chemistry is shown to be dependent upon the presence or absence of amalgam. White blood cells (our primary defence against disease) are sensitive to mercury changes in our bodies. Among these white blood cells are the immune cells called the "natural killer cells" whose primary function is to eliminate cancer cells. There is quite an uproar among NK cells as amalgam is removed and replaced. This brings up the question of why are these cells so responsive to mercury? Does this affect our resistance to cancer?

Cholesterol and CPK (creatine phosphokinase) are suggested to be indicators of susceptibility to heart disease. There is a notable change in these two values when amalgams are removed. Diet and exercise were unchanged in these patients -- the primary variable was the presence or absence of amalgam.

Current Examinations of the Biological Effects of Root Canals

Root canal procedures are becoming more frequent world-wide. Last year US dentists performed the procedure about 26 million times. Just what effect is this having on the population? Certainly many teeth are retained that would have been extracted, many bridges are in place instead of removable partial dentures, and some dentures are more comfortable because of the stabilizing effect of root canal teeth under them. But these are mechanical aspects. What are the changes (if any) in human health due to the presence of non-vital teeth?

In order for a root canal procedure to be considered successful, the canal must be adequately sterilized, all canals must be adequately filled, and the tooth must be solid and free from pain. According to the American Endodontic Society, not all root filled teeth meet these criteria.

Recent research has examined endodontically treated teeth to determine how a root canal tooth differs from a healthy tooth. Recently extracted 3rd molars with no caries, fillings, or obvious infection were used as controls and compared in abscessed teeth and to root canal teeth.

The external surface of the root was the focus of these studies, and it was determined that most 3rd molars contained no proteins or toxic chemicals unless a periodontal infection was around them at the time of extraction.

Periodontal ligaments of unhealthy teeth or root canal teeth in some cases (actually over 50%) did contain unusual chemicals. These chemicals were isolated and tested with gel electrophoresis for identification. Patterns of proteins were noted that seemed to correlate with diseases that the patients exhibited. Health improvements were noted when these teeth were removed, if the periodontal ligament was surgically removed from the socket after extraction.

Further investigation was done to identify the chemicals that were found in periodontal ligament. These chemicals are probably exotoxins from the bacteria trapped in the dentinal tubules. It is possible that these chemicals had migrated to the periodontal ligament. Chemicals, of course, are not subject to control by antibiotics. If these chemicals are not physically removed, the top of the socket heals over with 2 to 3 millimeters of bone, and the root space remains somewhat intact in form, but lined with the chemicals and bacteria that produce them. This unhealed area is termed a cavitation. Contamination of the unhealed areas was found to contain unhealthy chemicals in well over 95% of the cases investigated. Since these cavitations are actually areas of air within bone, they are exceedingly difficult to identify by X-ray.

Isolated extracts of these chemicals were introduced to several of the more important enzymes in our bodies. This soon suggested that there is more than one toxic chemical involved. Destruction of essential enzymes could lead to reduced efficiency in several of the critical biological pathways in our bodies leading to the onset of disease. Suggestions of connections between enzyme alteration and disease onset will be made. Genetic predisposition plays a role here, and the question becomes "is the toxicity of the chemicals strong enough to overcome genetics, or can one of these chemicals produce multiple problems depending upon one's genetic defense versus its weak link?"

It is scientifically possible, although expensive, to determine the presence of chemicals in the periodontal ligament after extraction, but what about before extraction? Not every root canal tooth is infected with this problem. Recent developments have found a method of testing the tooth in vivo to determine whether or not it contains any harmful toxins. This test, together with a review of one of several blood tests, may be able to increase our abilities to determine which root canal teeth are safe for our patients and which are doing more harm than good.

Should it be determined that a root canal tooth requires removal, there is a procedure that can reduce the possibility of the extraction site from becoming a cavitation that will require intervention later.

Hal A. Huggins, DDS, MS

During the past 30 years, Dr. Huggins has lectured over 1200 days to professional and lay groups, given over 900 radio, TV and print media interviews, published over 50 articles, edited an orthodontic journal and published two books, It's All in Your Head, and Why Raise Ugly Kids. During his spare time, he has discovered astounding research that has rocked the dental profession in the USA and in other countries. His studies led to the breakthrough that many people suffer immune suppression due to the presence of their dental fillings. This challenged the 1600 year old assumption that silver-mercury fillings as well as other toxic metals were safe simply because they had been used previously.

During his research in the toxicity of mercury and other dental materials, he has found out that chronic fatigue and a wide array of auto-immune diseases may be linked to these materials. He has developed a system that improves the quality of the immune system and allows many of these diseases to disappear, but it requires a series of blood studies and several years of preparation before fillings are replaced. Dr. Huggins has developed a blood test to determine which dental materials are "compatible" with an individual's immune system (different in each person, just like drug reactions) which disclosed that many dental materials cause immune reactivity in over 40% of the people tested.

To find out more about these two important topics as they relate to you or your patient's health, a week end seminar on November 22-23 in White Rock, British Columbia, has been planned to review clinical applications of all of the above points. Learn to read a CBC and Chem screen to see if dental problems are creating illness. For information phone Linda Brett at Helios Institute, 250-53 74419. Limited seating, so please register early.

Blood is one of the most important constituents of our body, it carries all the necessary nutrients as well as diseases too, so you need to be very careful when dealing with blood, if you don't complete the necessary tests then the patients are in great trouble, its always better to take services from umbilical cord blood banking centers who have experience in blood transfers
