Biological Dentistry

Story at a glance

Scope of Biological Dentistry

Although there are two professions –medicine and dentistry– the mouth never left the body. In fact, the tube that begins with the mouth and ends at the anus is about 30 feet (10 meters) and is the central aspect of life since all nutrients other than gasses, like oxygen, must enter through the mouth and travel down the tube, except of course what is absorbed through the skin.

The mouth has 32 teeth, which have their own vascular system, nervous system, and lymphatic system and perform both mastication (chewing) and articulation (it is sort of a moving joint that must come to rest when the mouth closes, i.e., biting down).  The quality of the bite, which serves as the first of the 8 cervical vertebrae is dependent upon how well the teeth fit into each other and that determines via the angle of the bite whether or not the spine and all of its nerves are straight from the top of the spine to the end at the sacrum. These are 32 different organs and if one loses its vitality or is overcome with microorganisms, it affects the adjacent teeth, as well as the jawbone in which it is rooted. Furthermore, the “bite”, known as “occlusion,” is greatly affected and determined by the joint that stabilizes the two jaws, the temporal mandibular joint (TMJ). The TMJ and the rest of the jaw bones depend upon their ability to grow and form healthy bones or not and serve as a place where the tongue can do its various jobs of tasting and speaking, etc. It may have grown in an unhealthy manner where it is too short and must be corrected.

Furthermore, the airway from the back of the mouth up through the back part of the nasal cavities and down past the tongue to the lungs is the passageway whereby oxygen and other elements in the air are delivered to the lungs so that gas exchange can occur to bring oxygen to our blood as well as release and expel carbon dioxide; this is called the airway. If this is compromised, then the whole body will suffer from less oxygen.

The final pieces of the puzzle that makes up this three-dimensional masterpiece, the head are the cranial bones on the top of the head.  As a fetus, there are seven bones so that during birth the head can negotiate the birth canal without causing bone fractures. If these seven bones do not fuse together properly, there will be a lack of balance, which changes the TMJ and hence the spine along with all the nerves and autonomic nervous system. Even after a healthy birth where the cranial bones fuse correctly, the trauma of an accident of some kind affecting the head or continuous minor trauma and irritation from bruxism (teeth grinding) can affect the TMJ, hence the whole spine.

Biological dentistry understands that the health and well-being of the mouth are essential to the health and well-being of the whole person.

Meridian System

Just like circuits in homes, there are circuits in biological organisms.  If the bathroom, kitchen, and bedroom lights go out, replacing the fuse in the circuit breaker box for that circuit will reactivate the circuit and the lights will go on. The same short circuits exist connecting various organs to others. Because the teeth, when closed, form the top vertebrae of the spine, where the nervous system communicates with the brain, all of the circuits (meridians) come through one or more teeth. Hence, charts have been produced that illustrate these meridians, such as the one below.

Therefore, if there is an infection or dental material that disrupts the flow of electricity in a circuit, all the components of that circuit are affected, i.e., less energy becomes available to the whole circuit and the component organs. Metals in the mouth short circuit the energy flow in that meridian (circuit) like opening the roof for it to escape. And, if there are two or more dissimilar metals in the mildly acidity of the saliva, an electrical current is produced that disrupts the circuits of the two or more teeth involved, known as oral galvanism, which increases corrosion and breakdown of amalgam fillings. Furthermore, these electrical currents increase the amount of mercury vapor and even free mercury that is released from amalgams, and tiny particles are released into the mouth. Finally,  this electrolytic process is exacerbated when gold crowns come into contact with mercury fillings.

The strength and significance of these meridians in most cases places its correction as the first or one of the first areas to be corrected with up to 80% of systemic illnesses, especially CFCs. For example, if one has an area of osteonecrosis (dead bone) in the jaw, known as a cavitation or a root canal or metal, an organ associated with that tooth is quite often the site of dysfunction and very often develops into CFCs. By not correcting this, which has played such a significant role in the development of CFCs, any medical intervention or program will be useless.

The International Academy of Oral Medicine and Toxicology (IAOMT) is an organization for dentists, physicians, and allied researchers who consider biocompatibility to be their primary concern and who demand scientific evidence as their key criterion. This group was founded in 1984 by a group of 11 dentists, one physician, and one lawyer during a seminar regarding the dangers of mercury from dental amalgam fillings. They realized that there was no scientific evidence to support mercury so they founded this group in order to conduct research so that they could scientifically justify the use of any substance or procedure required to practice dentistry in a safe and effective manner without causing harm. Over the past 40 years, they have amassed a large library of scientific literature that identifies what is and what is not safe and effective for dentists to use to help their patients achieve true oral health. 

IAOMT offers both training and certification that is both respected and accepted by the professional community of dentists, who have chosen to provide dental services at the highest level of quality without causing harm. Their motto is “Show me the Science”.

Dental Mercury and Other Metals and Alloys

Heavy metals such as arsenic, mercury, cadmium, uranium, and lead are harmful to people even in very small amounts. The most common metals used in modern dentistry are stainless steels, nickel-chromium, cobalt-chromium, titanium, and nickel-titanium alloys. When two or more metals are combined, they can become stronger forming what is known as an alloy, or metalloy. 

Stainless steel is made by combining iron and carbon in a two-step process. Furthermore, in order to produce corrosion-resistance chromium (Cr) and other alloy metals such as nickel (Ni) are added. The International Agency for Research on Cancer classifies hexavalent chromium and nickel compounds as group 1 carcinogens, i.e., carcinogenic to humans. Both short and long-term exposure to either cause multiple health problems, including cough, expectoration, wheezing, rhinitis (dripping nose), conjunctivitis (inflamed eyes), and contact dermatitis (redness, scaling, and hardness), as well as CFCs of the lungs and nasal cavities.

The National Cancer Institute states on its website: “Exposure to various nickel compounds increases the risks of lung cancer and nasal cancer.”

Dental amalgams are the most used fillings and are considered “safe and effective” for filling a cavity for the treatment of tooth decay. These amalgams are composed of approximately two equal parts:

  1. Liquid mercury
  2. A powder containing silver, tin, copper, zinc, and other metals

There are five other types of materials used to fill defects, or cavities in teeth that have decay:

  1. Resin composite
  2. Glass ionomer
  3. Resin ionomer
  4. Porcelain
  5. Gold alloys

Composite fillings often contain bisphenol-A (BPA), a known endocrine disruptor. BPA mimics estrogen by binding to both estrogen receptors α and β, which contributes to cell proliferation (division and growth), apoptosis (cellular death), or migration and, hence, contributes to the development of CFCs as well as their progression. Furthermore, glass ionomers contain either or both fluoride and aluminum, which off-gas (vaporize) with chewing food or gum, as well as when drinking warm or hot drinks. 

A large body of evidence has accumulated in the scientific literature regarding the facts that amalgams release mercury in significant quantities, resulting in significant amounts of exposure for people with these fillings and that chronic exposure to mercury in these quantities can damage the nervous system, kidneys, liver, and immune system. Simply breathing mercury vapors during the drilling can harm the nervous system, lungs, and kidneys of the patient, the dentist, and the dental assistant.

Removing amalgam fillings without taking precautions, can release mercury vapor into the air which is then either inhaled, absorbed through the skin, or swallowed. This is dangerous for both the patient, and the dentist, as well as other people within proximity. Multiple studies in several countries have demonstrated that people working in dental offices that remove amalgams have developed impaired color vision, dementia, weakness, impaired hearing, impaired taste, memory loss, blurred vision, loss of motor skills with walking (cerebellar ataxia), spasticity, rigidity, numbness, impaired voluntary movements (akinesia), difficulty speaking (dysarthria), impaired smell, tremors, and depression. Studies in Scandinavia have documented that dentists chronically exposed to mercury were found to have an increase of amyloid protein in the brain associated with Alzheimer’s, deterioration of microtubules within nerve cells (neurons), and an increase or inhibition of neurotransmitter release from motor nerve nerves that control movement. Therefore, there has not only been an increase in Alzheimer’s, but also multiple sclerosis, and mood disorders, yet the link between an increase of suicide in the dental profession to mercury exposure has been a matter of considerable debate.

On July 1, 2016, the IAOMT protocol for safe mercury amalgam removal was renamed the Safe Mercury Amalgam Removal Technique (SMART) and has been providing a training course for dentists and their staff who intend to remove these types of amalgams.

Clinical Nutrition and Heavy Metal Detoxification for Biological Dentistry

Unfortunately, only some biological dentists have regular programs of heavy metal detoxification with chemical chelating agents such as DMPS and DMSA, as well as nutritionally based chelators including both spirulina and chlorella. Numerous studies in both the U.S. and Europe have found chlorella is also able to break down hydrocarbon (oil) and metallic toxins such as mercury, cadmium, and lead, as well as organic toxins DDT and PCB (Polychlorinated biphenyl).

Chlorella is a single-cell green alga, in the phylum Chlorophyta and contains a very high content of chlorophyll and is an effective metal, including mercury chelator. Spirulina is a microscopic and filamentous cyanobacterium algae, with much the same chelating properties as chlorella, while it serves as a complete protein food source. 

Biocompatibility and Oral Galvanism

In addition to using dental materials that are seemingly less toxic, people who are extremely sensitive can have an allergic reaction (immunological intolerance) to almost any material, therefore, biocompatibility testing is required before placing any material in a person’s mouth. The more a patient suffers from allergies, environmental sensitivities, or autoimmune conditions, the more relevant this service becomes.  In addition to provoking an immune response, as stated previously, metals are electrically active. Oral galvanism, as previously discussed, has been understood for over 100 years, however, regular dentists ignore it and its complications.

Several companies test patient’s blood against over 2,000 dental materials to ascertain whether the product is “safe” or “not safe” to be placed in any particular individual’s mouth. Hence biocompatibility testing allows the dentist to select the dental material that is most compatible for each person. It must be kept in mind that not one single dental material is “safe” (non-reactive) for all patients. Making this service available to all patients should be the standard of care.


In the 1920s, aluminium manufacturing for the canning industry was robust. However, the process of producing the aluminium cans resulted in a toxic waste product called sodium fluoride. Since the processing was expensive, they sold the waste sodium fluoride as an insecticide and rat poison. 

On October 1, 1944, the Journal of the American Dental Association (ADA), warned that “the potentialities for harm (from fluoridation) far outweigh those for the good.” Andrew Mellon, the founder and major stockholder of ALCO, became Secretary of the Treasury in charge of the US Public Health Services (PHS). Then, in 1947, he appointed Oscar R. Ewing as head of the Federal Security Agency to begin a campaign to fluoridate the water system of the United States. Although there were no studies to show any benefit, they used advertising slogans, “Numerous studies have shown…” and “Research has proven….”, “Scientific investigators have found…” but they did not actually cite any articles. He arranged for ALCOA (aluminium company) to fund Gerald J. Cox, a scientist who in turn publicly stated that fluoride was necessary for healthy teeth in order to fight cavities, and then went on to propose that the USA should fluoridate its water reservoirs in 1939.

Then in 1955, the New England Journal of Medicine published a study showing a 400% increase in the incidence of thyroid cancer in the years after water began to be fluoridated in San Francisco. 

What the studies actually show is that fluoride doesn’t stop tooth decay at all, but instead proves that fluoride is neurotoxic and causes birth defects, and osteoporosis. As much as 50% by volume and 70% by weight of bone is a modified form of hydroxyapatite, known as bone mineral. Hydroxyapatite is the hydroxyl (OH−) component and apatite is the other component that constitutes this molecule. The OH− ion is often replaced by fluoride or chloride, producing fluorapatite or chlorapatite. This is a different molecule and does not have the same activity and children can develop brown, yellow, or green colorations, known as dental fluorosis.

Fluoride also damages the immune, digestive, and respiratory systems as well as the kidneys, liver, and brain and can lead to learning disabilities, including dyslexia, ADHD, autism, and CFCs of the bones (osteosarcoma) and bladder CFCs.  “Fluoride causes more human cancer, and causes it faster, than any other chemical . . . more people have died in the last 30 years from cancer connected with fluoridation than all the military deaths in the entire history of the United States.” This is a quote in 1977 by Dr. Dean Burk, epidemiologist, and former head of the US National Cancer Institute’s cell chemistry division.  It can be found in the Congressional Record, 21 July 1976.

The Food & Drug Administration (FDA) in the USA now requires that all fluoride toothpaste sold in the United States put the following poison warning outside and visible:

“WARNING: Keep out of reach of children under 6 years of age. If you accidentally swallow more than used for brushing, seek professional help or contact a poison control center immediately.”

This is because small doses of fluoride can produce symptoms of acute fluoride toxicity (i.e., poisoning). Early symptoms of fluoride poisoning include abdominal pain, nausea, vomiting, and headaches. The minimum dose that produces these symptoms is 0.1 to 0.3 mg/kg per body weight. So, A child weighing 10 kilograms will have symptoms of acute toxicity just 1 to 3 milligrams of fluoride in a single sitting.

There are 1 to 3 mg of fluoride in only 1 to 3 grams of toothpaste (less than 3% of the tube), including the bubble-gum and fruit flavor toothpaste marketed to children.

In the South Asia Journal of Cancer, a study in India found a link between fluoridated water and osteosarcoma in males 10-24 years of age. When compared to a control group of 10 people who did not drink fluoridated water, there were significantly higher serum fluoride levels in osteosarcoma patients as compared to healthy controls. Fluoride was found to have a mitogenic effect on osteoblasts (bone stem cells), which causes genetic damage. 

A national case-control study published in 2006 by Harvard scientists found that boys exposed to fluoridated water during their 6th, 7th, and 8th years of life had a significantly elevated risk of developing osteosarcoma during adolescence, whereas this association was not found for females.

In a 1987 Swedish Dental Association publication, mercury concentrations were determined in the brain and the kidneys in people who had mercury amalgams. The authors, M Nylander, L Friberg, and B Lind, found both brain and kidneys that were biopsied and tested at autopsy from 34 individuals showed a statistically significant relationship between the number of tooth surfaces containing amalgam and the concentration of mercury in the occipital lobe cortex. 

In the same study, looking at the kidney cortex of 7 cadavers who had amalgams, it was found that on average a significantly higher mercury level in those with amalgams than those of 5 amalgam-free individuals.

Finally, in this same study, in 6 cases where the analysis of both inorganic and total mercury was carried out a high proportion (mean 77% SD 17%) of inorganic mercury was found. It was therefore concluded that the cause of the association between amalgam load and mercury in brain and kidney tissues was due to the release of mercury vapor from amalgam fillings.

In the Environmental Research Journal published in 2018, looking at the health impacts on dental personnel regarding mercury exposure found weakness, fatigue, and anorexia along with central nervous system (brain) health problems. The article therefore concluded that the “use of dental amalgam in industrial countries is about to be phased out. In Norway and Sweden, the use of the filling material is banned.”

Only a few countries fluoridate their water, such as Australia, Ireland, Singapore, and Brazil, as well as the United States. Western Europe has rejected fluoridated water for their people, yet dental decay is increasing in both Western Europe and the United States at the same rate, in spite of the many decades of fluoride use. 

Root Canals

When it is clear that a tooth has too much decay to be saved, a root canal procedure is usually performed by an endodontist or general dentist. The entire pulp along with the blood vessels, the nerves, and lymphatic vessels are removed and irrigated. Then the empty tooth is filled with a rubber-like material called gutta-percha along with an adhesive cement to ensure complete sealing of the root canal. Because the tooth is now dead, having no blood supply, nerves, or lymphatic drainage, the natural physiology of the body is designed to reject the dead tooth just the same as it would reject any dead organ or tissue. Hence, every tooth with a root canal develops a low-grade focal infection. Since there are no nerves and no access by immune cells, an inflammatory response cannot occur, and the microorganisms will multiply and mutate with the person remaining completely unaware of the infection and having any symptoms for years and decades.

The billions or trillions of anaerobic bacteria that were never removed and those that colonized the remaining roots of the teeth, continue to live and feed off the dead material. The infection can and does spread from its focal origin to other adjacent areas of the jawbone, hence affecting other meridian systems.

All of the biotoxic metabolic byproducts enter the bone of the jaw causing infection and then move through the blood and lymph vessels that supply the bone where they are circulated around the body.

Jawbone Osteonecrosis (Cavitations)

During a standard dental extraction, the periodontal ligament is left attached to the bone of the jaw teaming with microorganisms, and then the area is irrigated, and the patient is given gauze and some pain medicine.  As the gums close over the wound and it heals, the microorganisms find their way into the jawbone away from a strong blood supply where they cause bone destruction and “build a cave”. This area of osteonecrosis (dead bone) serves to protect the microorganisms and they are free to flourish with no immune surveillance. Whichever meridian this cavitation covers will be affected and all of the connected organs. 

Root Canal and Oral Dysbiosis and Cancer

The presence of certain bacteria in the oral cavity have been found to be closely associated with pancreatic cancer as well as many other cancers. There are four mechanisms discovered that demonstrate the role of oral microorganisms in CFC development and progression and ultimately metastases. 

  1. Chronic inflammation is caused by the microbes that activate both oncogenes and mutations.
  2. Preparing the TME so that it is suitable for CFC stem cell growth and proliferation
  3. The production of carcinogenic substances, free radicals, and organic acids, that are necessary for CFC development.
  4. Bacteria in the infected root canals cause “epithelial to mesenchymal transition”, necessary for mature CFCs to behave like stem cells and take root.

Thus far, Streptococcus sp., Porphyromonas gingivalis, Fusobacterium nucleatum, and Actinomyces sp., have been found to be involved in the development of oral squamous cell carcinomas and oesophageal CFCs, as well as colorectal and pancreatic CFCs.   

The mechanisms that link root canal infections to distant organs include: 

  1. Metastatic infection due to bacterial seeding the blood since there were no immune cells present to eliminate them
  2. Next, the bacteria produce exotoxins and proteins that damage the cells. 
  3. Finally, inflammation is due to bacterial antigens, activating antibodies once they enter the bloodstream resulting in both acute and chronic inflammatory states in their new homes.

Whole Body Dentistry

Whole Body Dentistry also includes working with the cranial bones to bring them into alignment, which is necessary for the TMJ joint to be aligned, and that influences the bite, which as stated serves as the 1st cervical vertebra (top of the spine).  Most biodentists work closely with a cranial osteopath, who is trained to bring people’s cranial bones back into alignment. 

Furthermore, biodentists find that far more people than one would imagine are “tongue-tied” (ankyloglossia) meaning that their tongue is not able to move as high as it should or could due to its connection to the lingual frenulum that attaches the tongue to the floor of the mouth. Releasing it brings those who have lived with that condition their whole lives extreme relief and improves everything from eating to talking to smiling. 

And, as discussed previously, assessing and improving the airway increases the oxygenation of the body and allows people to sleep a full night and feel restored and refreshed, which they may not have experienced in many years.
