2025 research has shown clearly that the more amalgam filling you have, and the greater the surface area of those fillings, the higher the concentration of mercury in your urine. But is it dangerous?
According to the research (1), the reason is that the fillings release mercury vapour that finds its way into the bloodstream.
Dental Amalgam contains 50% of Mercury by weight; other elements used include silver, tin, copper, and zinc.
The research studied 180,811,187 Americans between the ages of 18–70 years-old, all with known dental amalgam fillings. The more fillings you had, and the greater the surface area, the higher the concentration of mercury in your urine. Chewing helps release the mercury vavour. And Chewing gum is certainly not helpful.
Amalgam fillings and the USA?
The key questions include ‘Do higher concentrations link to increased health and cancer risks?'
In America, the FDA: considers amalgam safe for adults and children over 6 but acknowledges potential risks for high-risk groups (pregnant women, children under 6, individuals with kidney impairment, or specific genetic sensitivities like ApoE4).
Approximately two thirds of adults have amalgam fillings. They have been a standard practice in dentistry for 150 years, where people have cavities.
Amalgam fillings and the EU
In contrast, the European Union: Implemented a comprehensive ban on mercury dental amalgam from January 1, 2025, aligning with the Minamata Convention to phase out mercury due to environmental toxicity and precautionary health concerns.
The UK is not in the EU, and so has not made a decision yet.
IARC, the International Agency for cancer research considers elemental mercury and inorganic mercury compounds as Group 3 (not classifiable as to carcinogenicity), reflecting inadequate evidence in humans.
Is Mercury safe?
Mercury is a potent neurotoxin that readily crosses the blood-brain barrier and placental barrier, accumulating in brain tissue due to its lipid solubility and affinity for fatty tissues, which comprise approximately 60% of the brain (2).
Mercury is highly nephrotoxic, with the kidneys serving as the primary site for the accumulation and retention of inorganic mercury compounds (3). Chronic or acute exposure can result in severe renal pathologies, including acute tubular necrosis, proteinuria, nephrotic syndrome, and chronic kidney disease.
Can mercury cause cancer? Research indicates that while epidemiological data is contradictory, mercury may promote carcinogenesis through oxidative DNA damage, genotoxicity, and epigenetic effects. Some studies have observed associations between high mercury levels and increased risks of skin cancer, breast cancer, and other malignancies, potentially via interference with oestrogen receptors and DNA repair mechanisms.
In summary - Mercury and its forms, even in the smallest doses, cause numerous disorders to the body, including to the nervous system, the respiratory system, and the cardiovascular system. It can cause disorders such as various cancers; endothelial dysfunction; gastric and vascular disorders; liver, kidney, and brain damage; hormonal imbalances, miscarriages, and reproductive disorders; skin lesions; vision damage; and even death.

How can you expel Mercury from your system?
Organic green juices including broccoli, wheatgrass, coriander (cilantro) and chlorella can help reduce mercury, especially if you add agents such as zeolite. Selenium 200 mcg a day can also bind to and neutralise mercury.
There are reports that Intravenous vitamin C can also remove mercury from the body.
If you are really concerned, you can visit an Holistic dentist to have the amalgam fillings replaced. I will be asking Elmar Jung a top holistic Dentist in the UK about this in my forthcoming Sunday Show.
I had mine completely replaced 25 years ago.
