Mercury in fillings — can amalgam in the mouth be harmful?

Sources: 10 · Article: 11 056 characters

Piotr Witczak believes that amalgam can be harmful because he lists it as a source of mercury and links mercury to disorders and diseases.

  • Piotr Witczak cites studies indicating a link between having amalgam fillings and multiple sclerosis, and also describes similar reports concerning ALS.
  • Piotr Witczak recommends avoiding sources of mercury and removing amalgam fillings, but only with appropriate safeguards.
  • The cited reports describe associations and possible risks; they do not prove that every filling causes disease.

What the authors write

Piotr Witczak

Amalgam fillings are listed as one source of mercury in the body.

„Examples of significant sources of mercury include amalgam fillings, some vaccines, broken mercury thermometers and CFL light bulbs, as well as prenatal exposure (the transfer of heavy metals from the mother's body to the fetus) and less significant sources such as fish and seafood (especially large predatory fish), tattoos, and many others.”Przykładowe, istotne źródła rtęci to wypełnienia amalgamatowe, niektóre szczepionki, rozbite termometry rtęciowe i żarówki typu CFL, a także ekspozycja prenatalna (transfer metali ciężkich z organizmu matki do płodu) oraz mniej znaczące źródła, takie jak ryby i owoce morza (w szczególności duże ryby drapieżne), tatuaże i wiele innych.

Andrzej Frydrychowski identifies amalgam fillings as a source of mercury and links long-term exposure to low doses of heavy metals with possible adverse effects.

„Amalgam fillings are a source of mercury in our bodies. Vaccines are another source of mercury in the body, causing an increase in autism cases. Heavy metals are added to vaccines as adjuvants to strengthen the immune response to the administered antigen.”Źródłem rtęci w naszym organizmie są plomby amalgamatowe. Szczepionki to jedno z kolejnych źródeł rtęci w organizmie, wywołujące wzrost zachorowania na autyzm. Metale ciężkie są dodawane do szczepionek jako adjuwanty, celem wzmocnienia poszczepiennej odpowiedzi odpornościowej na podany antygen.

Piotr Witczak cites publications indicating a link between having amalgam fillings and multiple sclerosis.

„There are currently at least several dozen scientific publications indicating a link between multiple sclerosis and having amalgam fillings. A similar situation applies to amyotrophic lateral sclerosis (ALS, Lou Gehrig's disease).”Aktualnie w literaturze naukowej mamy co najmniej kilkadziesiąt publikacji naukowych, które wskazują na związek między stwardnieniem rozsianym a posiadaniem amalgamatu. Podobna sytuacja ma miejsce w przypadku stwardnienia zanikowego bocznego (ALS, choroba Lou Gehriga).

Piotr Witczak describes reports of a link between mercury and ALS, but does not present them as proof that amalgam itself causes the disease.

„In the most recent review of studies (Newell et al., 2022), mercury ranked high among environmental factors associated with ALS. Earlier studies found that high mercury levels in fingernails are associated with an increased risk of ALS. Standard medical textbooks mention that both mercury and lead poisoning can easily be mistaken for Lou Gehrig's disease.”W najnowszym przeglądzie badań (Newell i in., 2022) rtęć była wysoko w rankingu czynników środowiskowych związanych z ALS. Wcześniej badania wykazały, że wysokie poziomy rtęci w paznokciach są związane z podwyższonym ryzykiem ALS. Standardowe podręczniki medyczne wspominają, że zarówno zatrucie rtęcią, jak i ołowiem, można łatwo pomylić z chorobą Lou Gheriga.

Piotr Witczak gives an example of an anecdotal story about a person whose health allegedly worsened after fillings were removed unsafely and new mercury fillings were placed.

„One example is the story of American investigative journalist Stacy Case, who was diagnosed with multiple sclerosis soon after her mercury fillings were removed unsafely and then replaced with four new mercury fillings.”Jednym z przykładów jest historia amerykańskiej dziennikarki śledczej Stacy Case, u której zdiagnozowano stwardnienie rozsiane wkrótce po tym, jak jej plomby rtęciowe zostały w niebezpieczny sposób usunięte, a następnie zastąpione czterema nowymi plombami z rtęcią.

Piotr Witczak recommends removing amalgam fillings safely, using appropriate procedures and safeguards.

„To do this, amalgam fillings should be removed, but always safely and with appropriate procedures in place. The Safe Mercury Amalgam Removal Technique (SMART) was developed by the International Academy of Oral Medicine and Toxicology (https://iaomt.org/).”W tym celu należy usunąć plomby amalgamatowe, ale koniecznie w sposób bezpieczny, z zachowaniem odpowiednich procedur. Procedura bezpiecznego usuwania wypełnień rtęciowych (SMART) została opracowana przez Międzynarodową Akademię Medycyny Jamy Ustnej i Toksykologii (https://iaomt.org/).

Piotr Witczak notes that chronic mercury poisoning can be difficult to identify.

„Chronic mercury poisoning is difficult to diagnose, especially if the exposure occurred many years ago and the person is not currently exposed. Elevated mercury levels may not show up in urine, blood, or even hair. Paradoxically, because of impaired detoxification mechanisms, people with a higher toxic burden may have even lower levels of toxic heavy metals in their hair or nails than people with a lower burden.”Przewlekłe zatrucie rtęcią jest trudne do zdiagnozowania, zwłaszcza jeśli do ekspozycji doszło wiele lat temu, a dana osoba nie ma bieżącej ekspozycji. Podwyższony poziom rtęci może nie ujawniać się w moczu, krwi, a nawet we włosach. Paradoksalnie, ze względu na upośledzone mechanizmy detoksykacji, osoby bardziej obciążone mogą mieć nawet mniej toksycznych metali ciężkich we włosach/paznokciach niż osoby mniej obciążone.

The review estimated that the dose of mercury from amalgam is low and that there is little evidence linking fillings to the health problems listed.

Aim of the study: Over the past 150 years, silver-tin-copper amalgam has been the most frequently used dental restorative material. Amalgam may be the single most frequently used implant material.

Results: As expected from the low daily dose, few adverse neurological symptoms have been reported. There is also little evidence of an association of amalgam restorations with neurodegenerative diseases, altered renal function, adverse pregnancy outcomes, or autoimmune diseases. There is a lack of data on neurobiological and neurodevelopmental effects on children who may be exposed to mercury from maternal amalgam restorations during gestation. Additional data on the role of amalgam, if any, in Alzheimer's disease and multiple sclerosis are needed.

The review concluded that the available evidence does not indicate that amalgam poses a health risk to patients.

Aim of the study: The use of dental amalgam as a restorative material has long been a contentious issue because of its elemental mercury component. While microleakage of mercury from amalgam has been conclusively confirmed over the past 30 years, intensive research has failed to identify deleterious health outcomes.

Results: On current evidence, international consensus heavily supports the statement that amalgam does not constitute a health risk to patients. However, exposure to volatile free mercury in dental clinics should be controlled to eliminate occupational risk. This paper provides a general review of the current situation and issues. It offers a consensus viewpoint for practitioners and lay people in reaching an informed decision on dental amalgam restorations.

The study found no link between amalgam fillings and Alzheimer's disease or higher levels of mercury in the brain.

Aim of the study: Mercury, or Hg, is a neurotoxin that has been speculated to play a role in the pathogenesis of Alzheimer's disease, or AD. Dental amalgam releases low levels of Hg vapor and is a potential source of Hg for a large segment of the adult population.

Results: The authors found no significant association of AD with the number, surface area or history of having dental amalgam restorations. They also found no statistically significant differences in brain Hg level between subjects with AD and control subjects. Hg in dental amalgam restorations does not appear to be a neurotoxic factor in the pathogenesis of AD. The authors found that brain Hg levels are not associated with dental amalgam, either from existing amalgam restorations or according to subjects' dental amalgam restoration history.

The risk assessment found that the combined intake of mercury from food and fillings is within the acceptable level.

Aim of the study: Next to nutrition, amalgam fillings represent the main source for exposure of the general population to mercury. Toxicological considerations focus on the dose of mercury resulting from such exposure.

Results: Introducing the dose into the known toxicokinetic model for mercury, tissue and blood and urine concentrations related to mercury release from the fillings can be predicted. These agree well with autopsy and in vivo observations. An assessment of the health hazard for individuals with amalgam fillings shows that the combined mercury intake from food and amalgam does not exceed the acceptable daily intake. In addition, blood and urine mercury concentrations of amalgam bearers are below one tenth of the critical values associated with the onset of early symptoms or of subclinical effects attributable to mercury.
