  1. What does Charlie Brown the president of the World Alliance for Mercury-Free Dentistry say about Amalgam fillings:

“Amalgam is a primitive, polluting, 19th century product that began when physicians were sawing off legs. Medicine has since moved forward.”

  1. What is an Amalgam filling?
    • An Amalgam fillings is a dental filling material.


  1. What is an Amalgam filling made of?
    • Dental Amalgam consists of a mixture of metals which include mercury, silver, tin and copper.


  1. Which component in Amalgam fillings is of concern?
    • The mercury component is of concern


  1. What is Mercury?
    • Mercury is a heavy metal that can be found in the earth’s crust.
    • Mercury is one of the most toxic substances known to humans


  1. Why are Amalgam fillings toxic?
    • Amalgamfillings contain at least 50% Mercury which is a known neuro toxin


  1. Are Amalgam fillings safe once they are in your mouth?
    • Amalgam fillings release mercury 24/7. This can be proven with a mercury vapour test.
    • If other metals are in your mouth even more mercury is released due to galvanic action.


  1. How much Mercury is released from Amalgam fillings?
    • A single dental amalgam filling releases up to 15 micrograms of mercury per day. This increases while chewing, especially chewing gum, drinking hot drinks or clentching and grinding your teeth. AND
    • If you have dissimilar metals in your mouth e.g a gold crown the release can be up to 10 times higher.


  1. How much mercury should we have in our body?
    • In an ideal world we would all have zero mercury in our body. However, due to diet, environmental exposure, dental treatment and other reasons, almost every person has at least trace amounts of mercury in his or her body.


  1. How toxic are amalgam fillings?
    • That depends on your susceptibility, your genetic disposition and the amount of mercury that is in the fillings and leaches out of them.


  1. What are the three forms of Mercury?
    • Metallic mercury also called Elemental mercury = Hg° = liquid mercury
    • Organic mercury = Hg+ = methylmercury = can pass through placenta
    • Inorganic mercury = Hg++ = formed when mercury combines with other elements such as sulfur or oxygen to form compounds or salts


  1. What are the sources of mercury?
    • Metallic mercury or elemental mercury is the mercury used in amalgam fillings and thermometers
    • Organic mercury is the mercury found in fish or used in vaccination as a preservative called Thiomersal
    • Inorganic mercury appears naturally in the environment including volcanoes, forest fires and fossil fuels such as coal and petroleum. It is used for example in cosmetic skin creams



  1. How do I know which kind of ApoE I’m having?
    • This can be tested in a Lab


  1. Why are amalgam fillings a problem for the brain?
    • Mercury affects autoimmune activation,  oxidative stress levels, neuroinflammation, causes neuronal damage and loss of connectivity


  1. Can mercury amalgam fillings make antibiotics resistant?
    • The genes for mercury resistance are carried on bacterial plasmids which also carry the antibiotic resistance gene.


  1. Why do dentists still use Amalgam fillings?
    • Some dentists still don’t see anything wrong with using amalgam fillings for their patients. Some even have amalgam fillings in their own mouth


  1. What are the benefits of Amalgam fillings?
    • They are cheap, easy to use, strong and long lasting


  1. What is the GDC’s (General Dental Council) opinion on Amalgam?
    • whilst some patients may choose to opt for mercury-free dentistry, patients should not be led to believe that the use of dental amalgam is unsafe.


  1. What is the BDA’s (British Dental Association) stand on Amalgam
    • The BDA has worked hard to avoid a full ban of dental amalgam for the Minimata Treaty of 2013


  1. What is the WHO’s (World Health Organisation) opinion on Mercury
    • Mercury is highly toxic to human health, posing a particular threat to the development of the (unborn) child and early in life.
    • The inhalation of mercury vapour can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal.
    • The inorganic salts of mercury are corrosive to the skin, eyes and gastrointestinal tract, and may induce kidney toxicity if ingested.


  1. What happened in Minamata?
    • The impact of mercury pollution was famously seen in Japan during the 1950s and 60s. Following mercury waste pollution in the waters, residents near the city of Minamata bay developed nerve disorders, resulting in more than 900 deaths.




  1. What does the WHO say about mercury, including its inhaled form (mercury vapour from amalgam fillings)?
    • “Mercury is highly toxic and harmful to health.
    • Approximately 80% of inhaled mercury vapor is absorbed in the blood through the lungs, causing damages to lungs, kidneys and the nervous, digestive, respiratory and immune systems.
    • Health effects from excessive mercury exposure include tremors, impaired vision and hearing, paralysis, insomnia, emotional instability, developmental deficits during fetal development, and attention deficit and developmental delays during childhood.”


  1. If I eat a lot of fish can I get mercury poisoning?
    • If you consume lots of fish high in mercury like Farmed Salmon, Atlantic Cod, Eel, Farmed Shrimp or King Crab, King Mackerel or Atlantic Bluefin Tuna it can take up to a year for your mercury levels to go down after you stop eating the mercury-rich fish.
    • When you eat seafood containing methylmercury, over 95 percent of the mercury can be absorbed into your bloodstream.
    • Methylmercury can travel throughout your body and penetrate the cells of various tissues and organs where it can remain stored up for years, which can cause symptoms that you may or may not realize are the result of mercury poisoning.


  1. What sort of fish are safer options in regards to Mercury?
    • Better options are Wild-caught Atlantic Salmon, Pacific Sardines, Atlantic Mackarel or Black Cod


  1. What are Mercury Poisoning Symptoms?
    • Symptoms of mercury poisoning can be numerous and may occur either rapidly or over long periods of time.
    • In general, symptoms occur and progress more rapidly the higher the dose of mercury encountered.
    • Exposure to the various forms of mercury can result in some similar and some different symptoms.
    • Symptoms can be grouped into three categories based on the form of mercury toxicity:
      • 1) elemental and vapourized mercury,
      • 2) organic mercury, and
      • 3) inorganic mercury


  1. What are Elemental and Vapourised Mercury Poisoning Symptoms?
    • Mood swings, Nervousness, Irritability and other emotional changes
    • Insomnia
    • Headache
    • abnormal sensations,
    • muscle twitching,
    • tremors,
    • weakness,
    • muscle atrophy,
    • decreased cognitive functions
    • High exposure to elemental mercury can cause
      • Kidney malfunction
      • Respiratory failure and
      • Death


  1. What are Organic Mercury Poisoning Symptoms?
    • Organic mercury toxicity (most frequently in the methylmercury form from ingestion), causes neurological malfunctions, and especially in a fetus, impaired neurological development.
    • Other symptoms include:
    • peripheral vision impairment,
    • stinging or needle-like sensations in the extremities and mouth,
    • loss of coordination
    • muscle weakness, and
    • other impairments of speech and hearing.


  1. What are Inorganic Mercury Poisoning Symptoms?
    • Inorganic mercury toxicity often causes
    • If ingested, it can dissolve tissues and some may be absorbed by the intestinal tissue.
    • Large amounts of ingested inorganic mercury may cause bloody diarrhea.
    • Absorbed mercury can spread to other organ systems resulting in mental changes including mood swings and memory loss or renal damage.
    • Muscle weakness may also occur.


  1. Is Mercury a problem when you are pregnant?
    • Many pregnantwomen have had methylmercury toxicity which effects their children.
    • The fetal brain is very sensitive to methylmercury;
    • developmental impairments such as reduced ability in thinking, attention span, memory, and most motor skills occur in various degrees, often severe, even if the mother developed few if any symptoms.


  1. What neurological problems can Mercury cause?
    • Tremor
    • Muscle weakness
    • Partial or complete paralysis
    • Partial or complete loss of sensation
    • Seizures
    • Difficulty reading and writing
    • Poor cognitive abilities
    • Unexplained pain
    • Decreased alertness.


  1. How can your dentist remove Amalgam fillings safely?
    • He can use the protocol from the International Academy of Oral Medicine and Toxicology (IAOMT) which explains exactly how mercury fillings can be removed in a save way.


  1. What is the IAOMT Protocol for safe Amalgam removal?
    • The full protocol can be found here




  1. Is there a connection between Mercury and Alzheimers
    • If you have specific genes, namely two ApoE4 (Apolipoprotein E) genes you are more likely to get Alzheimers
    • If you have the ApoE2 gene do not get Alzheimer’s
    • The difference between these two genotypes is that the ApoE4 gene has two arginine aminoacids and the ApoE2 has two cysteine aminoacids.
    • Cysteine gives you protection from mercury, whereas arginine does not.


  1. Are the Symptoms of Mercury Intoxication and Alzheimers disease similar??
    • Both have:
      • Neurofibillary tangles in the brain
      • Amyloid plaque formation by secretion of beta-amyloid
      • Abnormal tubulin GTP binding
      • Increased tau phosphorylation
      • Inhibited creatine kinase
      • Inhibition of glutamine synthetase


  1. Is there a connection between Mercury and Parkinson’s
    • Studies have found that some people with specific genetic mutations are more susceptible to environmental toxins, such as mercury.
    • The early in life exposure to these environmental toxins makes them more susceptible to Parkinson’s disease.
    • Mercury exposure also lowers the cell’s levels of Glutathione, Dopamine and NAD.
    • These cellular changes specifically target the portion of the midbrain that controls movement. The mercury sensitive patient then shows symptoms of Parkinson’s disease when they reach the age of about 60 years old.


  1. Is there a connection between Mercury and MS?
    • There are patents who after receiving amalgam fillings developed MS-like symptoms and were thereafter diagnosed with MS. Once the amalgam fillings were safely removed the symptoms subsided and the patients got their health back


  1. Is there a connection between Mercury and Cavitations?
    • Research from Germany has indicated that cavitations may hold a reservoir for heavy metals and other chemical toxins especially in the wisdom teeth areas.


  1. Is there a connection between Mercury, Alcohol consumption and pregnant women?
    • Alcohol increases the absorption of mercury vapour, therefor depositing the mercury in the mother’s thyroid and in the thyroid and liver of the foetus.
    • Mothers who drink alcohol during pregnancy increase the amount of mercury deposited in the unborn child from their own amalgam fillings


  1. Is there a connection between Mercury and ADHD?
    • A study presented in 2012 identified an association between prenatal MeHg (Methyl Mercury) and ADHD symptomatology in childhood in a population exposed to Mercury primarily from dietary sources
    • Researchers found that the child’s risk of developing ADHD increased to 40-70% at a certain threshold of mercury and that children were more likely to exhibit signs and symptoms of ADHD when 8 years old.
    • The study also showed that there was a greater association of ADHD symptoms with boys than girls.


  1. Is there a connection between Mercury and Autism?
    • The Autism Research Institute (ARI) is convinced that mercury is the primary cause of autism and related syndromes.
    • ARI has published a 70-page web document called Autism: A Unique Type of Mercury Poisoning.
    • They state: ‘The similarities between the symptoms of mercury toxicity and autism, considering the exposure to mercury of the foetus and child, suggest that autism is a form of mercury poisoning.’


  1. Is there still mercury in vaccines (Thiomersal)?
    • It is still used as a preservative for flu vaccines in multi-dose vials, to keep the vaccinefree from contamination.
    • Thimerosal is also used during the manufacturing process for some vaccines to prevent the growth of microbes.


  1. Why do they put mercury (Thiomersal) in vaccines?
    • Thimerosal is a mercury-containing organic compound (an organomercurial).
    • Since the 1930s it has been widely used as a preservative in a number of biological and drug products including many vaccines to help prevent potentially life threatening contamination with harmful microbes


  1. Where can I get more scientific evidence about the dangers of mercury?
    • here
    • WHO
    • Study “Toxic Effects of Mercury on the Cardiovascular and Central Nervous Systems”
    • Study “Mercury Exposure and Children’s Health”
    • EcoWatch


  1. How can I find out if my symptoms are caused by my amalgam fillings?
    • The range of possible mercury toxicity symptoms is quite large.
    • Symptoms differ depending on
      • the form of mercury,
      • the dose, and
      • the time period over which the mercury poisoning occurred
    • Exposure to a large amount of mercury in a short period of time can quickly lead to severe symptoms.
    • Low-grade, chronic exposure to mercury from dental amalgams generally causes more subtle and nonspecific symptoms


  1. What can you do if you think you have mercury poisoning from your amalgam fillings?
    • First, find a physician experienced in heavy metal testing and get an actual lab test measuring your mercury levels.
    • Quicksilver Scientific in the US have developed a Tri-Mercury test which is relevant also to your ability to detox.
    • Find a dentist experienced in safe Amalgam removal


  1. What can the dentist do to protect me when removing my amalgam fillings?


  1. Is mercury leaking out of my fillings?
    • Yes


  1. Is there a safe level that can leak out of my Amalgam fillings
    • No, there is no such thing as a safe level


  1. How can the mercury vapour leaking out of my fillings be measured?
    • With a Mercury Vapour Meter


  1. Is it dangerous if mercury leaks out of my amalgam filling?
    • This depends on your susceptibility
    • It is definitely not healthy


  1. Where does the mercury that is leaking out of my fillings store?
    • When Mercury enters the body, it is stored in the kidneys, blood, spleen, brain, liver, bones and fatty tissues


  1. Can mercury cause damage to kidneys?
    • Yes
    • According to research the kidneys are one of the most targeted organs of mercury


  1. Can mercury cause damage to my intestines?
    • Yes


  1. Can mercury cause damage to the brain?
    • Yes
    • Mercury can easily cross the Blood-Brain-Barrier


  1. Can mercury cause damage to the skin?
    • Yes
    • I once had a patient whos skin problems entirely disappeared after removing all her Amalgam Fillings


  1. Can mercury cause damage to the spine?
    • Yes


  1. Can mercury cause damage in my mouth?
    • Yes


  1. I have mercury fillings and gold crowns – is this a problem?
    • It most likely causes a galvanic action which means you have a battery effect in your mouth.
    • Parts of the mercury go into solution (in your saliva) and move to the more precious metal.
    • Sometimes you can see a blue tatoo around a metal crown. This is a mercury tatoo


  1. I have a mercury filling and a root filling – is this a problem?
    • The combination of decomposing products from a dead or root canal tooth, namely sulphurs and mercury can produce highly toxic compounds


  1. I am pregnant and have Amalgam fillings shall I have them removed?
    • This is a bit of a tricky one
    • Recommendation is to have all your and your partner’s Amalgam Fillings removed before you aim for offspring and also have the Mercury detoxed from your body
    • Once pregnant I would only embark on having Amalgam Fillings removed if a tooth needs treatment or you have a diagnosed problem with Mercury


  1. How is it possible that my child has no Amalgam Fillings but a lot of Mercury in their body?
    • A mother while pregnant or breast feeding will pass on between 40% up to 80% of her toxic load such as Mercury to the unborn or baby.


  1. Does it make a difference to the child if the father has also got some Mercury Fillings?
    • Yes it does


  1. What influence do parents have on their child`s mercury level?
    • According to research by Prof. Boyd Haley if both parents have Amalgam Fillings the capability of the child to eliminate the toxic load can be impaired.


  1. I have many amalgam fillings. Should they be removed in one session?
    • I recommend to discuss this with your dentist
    • Using IAOMT’s S.M.A.R.T. – like Protocol and VitaminC Infusion during the process I can’t see any reason why not.


  1. When should Amalgam fillings NOT be removed in one session?
    • If your dentist does not use IAOMT’s S.M.A.R.T. Protocol, but why would you go to a dentist who doesn’t


  1. Why am I more susceptible to mercury than other people?
    • This could be due to your genetics


  1. What do my genes have to do with my mercury problems?
    • If you have specific genes, namely two ApoE4 (Apolipoprotein E) genes you are more likely to be affected by Mercury
    • If you have the ApoE2 gene you are less likely to be affected
    • The difference between these two genes is that the ApoE4 gene has two arginine aminoacids and the ApoE2 has two cysteine aminoacids.
    • Cysteine gives you protection from mercury, whereas arginine does not


  1. When is the best time to have mercury fillings removed?
    • As soon as you become aware of them


  1. Why are boys more susceptible to mercury?
    • According to Prof. Boyd Haley, ethylmercury (the mercury from vaccines) has a particular affinity for testosterone, becoming increasingly more toxic in its presence compared to when it encounters estrogen.
    • This seems to explain why boys are about five times more likely to develop autism than girls
    • This further validates the connection between exposure to mercury and an increased risk of neurological disease.


  1. Candida and mercury fillings?
    • Mark Sircus, Brazil, says:
      • “Mercury vapors from dental fillings play havoc on the body through a host of means, the least of which is to feed the bacteria, fungi, and yeasts that thrive on mercury.
      • Mercury will promote the growth of Candida, though as it absorbs the mercury, it thereby protects the system to a certain extent from its toxicity – until they are saturated then they begin to re-release the mercury in organic form.”
    • Once your mercury fillings are removed and the a proper detox is completed, Candida overgrowth most likely resolves itself with little or no effort.




  1. What is a Root Canal?
    • A Root Canal Treatment is a dental treatment to avoid extracting a tooth


  1. How is a Root Canal Treatment done?
    • The pulp (nerve, blood vessels, lymph vessels) is removed leaving back a dead tooth


  1. What materials are used to fill the root?
    • The most common method of root canal treatment is to put a paste inside the canal and place a point of gutta-percha into the canal. The paste sets and the canal is sealed – that´s the theory
    • Commonly used is as paste is:
      • AH26 which contains formaldehyde, ammonia, silver


  1. What about the bacteria in the Root Canal tooth?
    • Bacteria from the main Channel are removed BUT
    • Bacteria hide in the microscopic small side tubuli
    • A tooth has up to three miles of these small channels


  1. Can there be problems with Root Canal?
    • It is impossible to remove all the nerve tissue from these small side canals.
    • Inside these canals, the nerve tissue rots away
    • This rotting tissue becomes infected
    • no antibiotic or chemical can reach these bacteria
    • There is no blood supply, so the immune system cannot reach this area and the bacteria which are or become anaerobic (living without oxygen) and live unhindered.


  1. Are Root Canal teeth toxic?
    • The bacteria produce wast.
    • This waste consists of complex protein toxins.
    • These toxins enter the body and can end up anywhere.


  1. How can you test for toxicity?
    • The toxins from a root-filled tooth can be measured using a OROTOX-Test
    • Fluid is collected from around the neck of the tooth and analysed.
    • The complexity of the proteins is in proportion to their toxicity.


  1. Why leave a piece of dead and rotting tissue in the body?
    • If your toe would die zour GP would tell you have a gagraene and recommend to have the toe cut off.
    • He would certainly not recommend to leave it. Because he knows this will within a short period of time poison the body.


  1. When is a Root Canal Treatment ok?
    • As an emergency treatment to reduce pain
    • If you are healthy person and understand the risks involved with a root canal treated tooth


  1. What is the alternative to Root Canal?
    • The only alternative to a Root canla Treatment is to have the tooth extracted


  1. What did Dr. Weston Price’s experiments show?
    • Price implanted root canal treated teeth from chronic ill patients under the skin of rabbits. Within days the rabbits developed the exact same chronic disease
    • If he implanted healthy teeth from these patients the rabbits would stay healthy


  1. Can Root Canal treated teeth affect other parts of the body?
    • Yes it can


  1. What is important when a Root Canal tooth is extracted?
    • Like with every extraction, the periodontal ligament has to be removed and the socket cleaned and scraped out thoroughly
    • Best practice is to also rinse with Ozone gas to kill remaining bacteria in the socket


  1. Can Ozone sterilize the dead tooth?
    • Unfortunately no treatment is capable of sterilizing a tooth


  1. What is the difference between a gangraene and a dead tooth?
    • Actually there isn´t any


  1. Can x-rays detect if a Root Canal tooth has a problem?
    • A lot of the times x-rays can show if there is a problem
    • Sometimes it is necessary to do more tests like the OROTOX


  1. What to do if a Root Canal gets infected
    • Mainstream opinion is to re-root treat the tooth
    • The alternative is extraction




  1. What is a Focal Infection?
    • The theory assumed that an infection in one part of the body could cause symptoms in another part of the body
    • The way this was supposed to work was that the organisms from the infection site would break away into the blood stream and be carried around in the blood vessels
    • This theory has been extended in recent years to include the release of toxins from organisms which they give off as waste products.


  1. When was the theory of Focal Infection first introduced?
    • Focal infection was a widely respected theory during the first half of the 20th century.
    • it was already mentioned in Dr. Thomas Bond Book “Dental Treaties” in 1848


  1. What are common Dental Sources of Focal Infections?
    • There are four main sources:
      • Cavitation or NICO infections in the jaw bone;
      • Root fillings;
      • Dead and infected teeth
      • Gum disease


  1. What is a Dental Cavitation?
    • Simply said, a dental cavitation is a hole in the jaw bone, often where a tooth has been previously extracted and the bone hasn´t healed properly
    • The cavitation itself forms a slimy mucilaginous membrane to protect themselves from the immune system


  1. How do cavitations develop?
    • Cavitations develop when the blood supply to the bone is disrupted


  1. How can a Dental Cavitation be diagnosed?
    • They can sometimes be detected on a x-ray but are not easily seen and are mostly overlooked
    • They can be detected by their smell (like stale smoke or a strong sour smell)
    • The most reliable diagnostic is by means of a Cavitat Scan.
    • The Cavitat scan shows the extent of a cavitation infection in 3D


  1. What is the most common reason for developing a cavitation?
    • The most common causes of cavitation infections are extractions.
    • Injuries such as whiplash, falling of a bike or horse are also common reasons for a cavitation infection to develop


  1. Why do dental Cavitations develop?
    • Cavitations occur when the blood supply to or in the bone is disrupted


  1. How can the blood supply in the bone be disrupted?
    • The blood supply can be interrupted by the trauma causing the bone to die which lets bacteria become established in the dead area.
    • Dental injections, overenthusiastic orthodontic treatment, impacted teeth, infected or dead teeth and root fillings are other causes.


  1. How long does it take for a cavitation to develop?
    • This can take years
    • it usually develops painless
    • no markers of an acute infection such as inflammation, redness or swelling


  1. Are there other ways to detect a cavitation?
    • Sometimes smell is a way of detecting a cavitation infection. This can happen if a fistula has formed from the cavitation into the mouth.


  1. Does it smell once a cavitation is opened for cleaning out?
    • Not all the times do we find a smell involved
    • If there is smell, there are two characteristic smells.
      • The most frequently encountered is the smell similar to stale smoke
      • The other smell is a pungent sour smell.
    • These smells are sometimes also present when a tooth is extracted or when cleaning out gum infections


  1. What is a NICO?
    • NICO is the abbreviation for Neuralgia-Inducing Cavitational Osteonecrosis)
    • This is when a cavitation is causing pain
    • This pain is often mistaken for toothache
