Mercury Amalgams


Overview: The following is intended to provide you with the basics of the Informed Consent that should precede any decision to replace these fillings.

Exposure to Mercury

Clinical research has shown that the inorganic mercury which binds these amalgam restorations together undergoes slow vapour release on a daily basis – [with removal and replacement creating very high acute doses].

Vaporisation is the most toxic form of mercury which gets absorbed into the system through inhalation and gut absorption. It then gets absorbed into the blood stream which disperses it throughout the body and deposits it in the cellular tissue where it becomes locked and can interfere with the natural organic functioning.

The web site below will present you with some pretty irrefutable evidence of this which would indicate that they are not safe – just tolerated [i.e. without any apparent symptoms]  by some individuals better than others.

Intake / Body Burden

This same web site will also present you with the evidence which, despite other claims to the contrary, definitively indicates that the mercury vapour released not only interferes with the functioning of the gut bacteria [with can lead to Gluten intolerance but also becomes lodged in, and interferes with, the natural & healthy functioning of the brain cells & body organs/ tissues .

Personal Assessment & Treatment

This falls into 3 Categories:

  1. Diagnosis /Assessment
  1. Mercury Sensitivity : Laboratory Test which indicates individual sensitivity.
  1. Urine Challenge Test : Simple Laboratory home kit test to assess your body burden
  1. Replacement Materials: Laboratory Test for their individual sensitivity.

Clinical Assessment

In my Clinic, this assessment takes 1 hour starting with a symptomatic assessment from the results of 3 completed pre consultation questionnaires related to possible mercury toxicity / intolerance.

The middle section of this consultation involves examining the current condition of your teeth, taking appropriate x-rays during which I would assess what nature intended, deviations from this intention followed by devising a personalised Treatment Plan categorised into short, medium and long term restoration solutions.

With suspect mercury toxicity, the emphasis will be on the materials / techniques required for amalgam replacement – within the context of the above overview.

From the results of these questionnaires and clinical assessment, we would then complete this consultation by designing a Treatment Plan which is compatible with your clinical requirements together with your health, personal and financial circumstances.

  1. Primary Symptomatic Mercury Sensitivity Assessment
  1. Replacement Materials:  assess the suitability as a Clinical Material [i.e. that it will satisfy the clinical restoration requirements of tooth / restoration seal, durability, function, tooth cusp protection etc.]
  1. Electrical Activity : all metallic restorations tend to produce an electrical charge which can help guide the optimal order of restoration replacement order. However, this electric charge may also be the main source of systemic dysfunction with the body’s natural electrical and within the oral cavity [both from amalgams and other metallic restorations]
  1. Full Regular Dental Assessment / necessary x-rays etc. with special emphasis on the clinical issues involved in this replacement.
  1. Informed Consent: given the very diffuse nature of mercury vapour and the multitudinous variations in human genetic, hereditary and life style attitudes, physical health, pre disposing factors, the effect [or apparent non effect] of this toxin will vary enormously – as will the speed and percentage improvement that may be experienced after the mercury filling replacement and its detoxification / cleanse up within the system.



  1. All amalgam metals are positive ions which means that, in combination they produce a  weak repulsion which results in a sustained release of mercury and other metals from the amalgam into the body.

Researchers have measured a daily release of mercury on the order of 10 micrograms from the amalgam into the body. Mercury is a toxic metal; the most minute amount damages cells.

  • every amalgam daily releases on the order of 10 micrograms of mercury into the body (i.e. 3,000,000,000,000,000 mercury atoms per day),
  1. There are five dissimilar metals in the amalgam which, as dissimilar metals form a battery,  produces an inevitable Galvanic action between these metals.
  1. Galvanism produces electricity that flows through the body. The electric currents produced by the amalgam typically are between 0.1 and 10 microamps, compared to the body’s natural electric current of 3
  1. Body ‘Implants’

Amalgam is the dental term for the ‘amalgamation’ [mixture] of the silver coloured fillings used to fill teeth. At the present time, based on 1992 dental manufacturer specifications, (at mixing) these typically contain approximately 50% metallic Hg, 35% silver, 9% tin, 6% copper, and a trace of zinc.

For more than 160 years dentistry has used silver amalgam, which contains approximately 50% Hg metal, as the preferred tooth filling material. During the past decade medical research has demonstrated that this Hg is continuously released as vapor into mouth air; then it is inhaled, absorbed into body tissues, oxidized to ionic Hg, and finally covalently bound to cell proteins. Animal and human experiments demonstrate that the uptake, tissue distribution, and excretion of amalgam Hg is significant, and that dental amalgam is the major contributing source to Hg body burden in humans. Current research on the pathophysiological effects of amalgam Hg has focused upon the immune system, renal system, oral and intestinal bacteria, reproductive system, and the central nervous system. Research evidence does not support the notion of amalgam safety.

Gram-negative fecal bacterial from three longitudinal Hg exposure experiments and from two independent survey collections were examined for their carriage of the mercury resistance (mer) locus. The occurrence of antibiotic resistance was also assessed in both mercury- resistant (Hgr) and mercury-susceptible (Hgs) isolates from the same collections. The longitudinal studies involved exposure of the intestinal flora to Hg released from amalgam “silver”

Dental restorations in six monkeys.

Hgr strains were recovered before the installation of amalgams, and frequently these became the dominant strains while amalgams were installed.

Such persistent mercury strains always carried the same mer locus throughout the experiments.

In both the longitudinal and survey collections, certain merloci were preferentially associated with one genus, whereas other mer lociwere recovered from many genera. In general, strains with any mer locuswere more likely to be multiresistant than were strains without mer loci;this clustering tendency was also seen for antibiotic resistance genes.

However, the association of antibiotic multi-resistance with mer loci was not random; regardless of source, certain mer loci occurred in highly multi resistant strains (with as many as seven antibiotic resistances), whereas other mer loci were found in strains without any antibiotic resistance.

The majority of highly multiresistant mercury strains also carried genes characteristic of an integron, a novel genetic element which enables the formation of tandem arrays of antibiotic resistance genes. Glutocorticoid Receptors strains lacking antibiotic resistance showed no evidence of integron components.

  1. Hi, I just stopped by to visit your blog and thought I’d say I enjoyed myself.

    I had mine removed and reodne. I told the denist I was nervous and ask him, if he would give me the liquid valium in the top of my hand. Done! I woke up. No big dealMy husband is right now opting to have a tooth pulled. He doesn’t want to go through the process.(removing crown, drilling etc. ) After we have taken such good care of our teeth. Not me. I want a beautiful smile forever. Hope you do too?

    I’m confused. Is it a good thing to replace an amalgam filling or not? I mean if disrupting it is so dangerous and releases toxins isn’t better to leave it as it is?
