This Amalgam-Related Illness, Frequently Asked Questions (FAQ) was
compiled by Leif Hedegard. This is version 2.9.1.
This FAQ is copyrighted: Leif Hedegard 1994-1997.
We know that: |
| - dental amalgam fillings consist of 50% mercury - mercury leaks from the fillings - mercury is highly toxic and - low grade chronic mercury intoxication can give rise to symptoms as; anxiety, irritability, fatigue, outbursts of temper, stress intolerance, decreased simultaneous capacity, loss of self-confidence, indecision, headache, depression, metallic taste etc... |
We do not know: |
| - if the amount of mercury released from dental amalgam is enough to cause illness, even in the most exposed or the most sensitive minority of the amalgam-bearing population. |
Please double-check everything in this FAQ before you
let it influence your thinking, there is a possibility that I have got
something wrong - please inform me
if so is suspected (be specific). If you are ill - you should see
a physician, this FAQ is not intended to replace a physician.
However you can read about symptoms / possible diseases, as a complement.
Abbreviations:
Hg = Mercury.
CNS = Central Nervous System.
1. Introduction- There has been concern and debate about potential / possible (non-allergic-) negative health effects from dental amalgam-fillings. At least several thousand scientific reports and discussion articles ...
2. Symptoms- 2.1 Symptoms in chronic inorganic Hg-intoxication. The heavy, mostly occupational, chronic inorganic mercury intoxication has been described as having a triad of symptoms: 1) Tremor (or more wi...
3. Is It Possible That Dental Amalgam Can Cause These Symptoms?- 3.1 Are we exposed to toxic levels of mercury from our amalgam fillings? Dental amalgam consists of approximately 50% (inorganic) mercury (by weight) ( DHHS 1993 page I - 2). Besides mercury the am...
3.2.3 Did These Individuals Get A Symptom Reduction After Amalgam Removal? - Reports stating that groups of people, suspecting that they have a (non-allergic-) amalgam-related illness, have reduced their symptoms, by up to 80%, after removing their amalgam-fillings have been p...
4. Do I Have A (Non-Allergic-) Amalgam-Related Illness?- 4.1 No approved diagnostic tests exists. As stated above (see sections 3.1-3.2.1): if there is a (non-allergic-) amalgam-related illness, it seems, at least on a group level in people who suspect t...
5. I Believe I Have A (Non-Allergic-) Amalgam-Related Illness - What Do I Do?- 5.1 Read. As long as (non-allergic-) amalgam-related illness is not an accepted diagnosis, very few dentists will minimise your mercury exposure during amalgam removal more than what standard proced...
5. I Believe I Have A (Non-Allergic-) Amalgam-Related Illness - What Do I Do? P2- 5.3.2 As long as there are amalgam fillings in your mouth. These are some of the factors that has been proposed to raise the mercury efflux from amalgam fillings in amalgam-bearers over the base-li...

5. I Believe I Have A (Non-Allergic-) Amalgam-Related Illness - What Do I Do? Concluded- 5.9 Chelators, for example DMSA and DMPS. A mercury antidote. Captures mercury and forces the captured mercury to be excreted, thereby lowering the body burden of mercury. Can cause unwanted side-...
6. Alternative Restorative Materials- Neither amalgam nor alternative filling materials has been biocompatibility tested or side effect reported in the same way as pharmaceutics has been for a long time. Although it is unusual, people can...
7. Mercury Sources. Is Amalgam Really The Biggest Mercury-Source?- 7.1 Mercury sources, overview. According to WHO (WHO 1991) these are the general sources of mercury in the body (ug / day): Air: 0.040 Fish 2.34 Non-fish food 0.25 Drinking-water 0.0035 Merc...
7. Mercury Sources. Continued- 7.3 Mercury dose/day from amalgam vs. toxic dose. The WHO Study Group writes about occupational exposure to mercury vapour in the air: Exposure in the range of 25 to 80 ug/m3... increases the inc...
8.1 Amalgam And Women In And Before Childbearing Age- At present, there is not scientific support for saying if amalgam is or isn't safe. A continued use of amalgam (as well as other materials) must be based on a calculation of risks and here a special c...
