The article states: Conventional amalgam alloy commonly consists of silver (~65% ), tin (~29%), copper (~8%) and other trace metals; current amalgam alloy consists of silver (40%), tin (32%), copper (30%) and other metals.[12]
However both of these alloys must be incorrect as the total content of silver tin and copper is over 100 %. In addition there must also be some mercury, which is not even mentioned. EV1TE ( talk) 08:38, 8 April 2020 (UTC)
They're several health professionals out there who believe dental amalgam restoration is regarded as a host to many dental diseases. Acncedotal cases report hugely influence some individuals. Steve Jeckson performs and in-depth investigation upon this element and analyses the data supporting and condemning the use of amalgam restoration. He reviewed articles from both peer-reviewed and non-peered review [1] sources and evaluated their significant relevance. Many experts, however, some has pointed out a range of logical and methodological errors in the anti-amalgam literature, in fact, the author has even concluded that evidence supporting the safety of amalgam restoration is quite compelling. Currently, amalgam restoration procedures are recognized by many institutions as safe and effective, however ethically, dentist still should educate their patients about the dangers of amalgam before allowing their patients to undergo surgery.
In the "Dental amalgam toxicity controversy" section, the text to external link 1 is inaccurate and lacks neutrality. The link is described as "University of Calgary video on Brain Degeneration caused by Mercury Fillings." But the actual UC video is titled, "How Mercury Causes Brain Neuron Degeneration [emphasis ours]." It is not titled, How Mercury Fillings Cause Brain Neuron Degeneration, because no part of it shows fillings causing brain neuron degeneration.
The video shows the use of a pipette to deliver drops of mercury to neurons growing in a petri dish. About 1/5 of the way through (no minutes:seconds are given), animation shows a pipette in the upper right, then zooms in to the petri dish containing purple growth media. Slightly past the 1/2 way point, following the time-lapse video of the actual mercury and neurons, the animation again shows the pipette in the upper right. Then the pipette dispenses drops of mercury onto the neuron. Nowhere does the video show mercury being dispensed or otherwise released from a dental filling. A dental filling is not used.
In the introduction, the narrator notes, "Over the past fifteen years, medical research laboratories have established that dental amalgam tooth fillings are a major contributor to mercury body burden." Certainly, from this video one may *infer* that mercury vapor from amalgam may degenerate neurons just like the mercury drops from the pipette; indeed, UC's narrative suggests that this inference be made. However, UC is careful to describe the experiment accurately, as it was actually done.
The "Dental amalgam toxicity controversy" is a section in an encyclopedia, so its purpose is not to debate, but to describe elements of the existing debate in accurate, neutral terms. Describing the video as depicting how mercury from fillings causes brain neuron degeneration is inaccurate, somewhat overreaching, and lacks neutrality. So we suggest that the video be described precisely as UC describes it. The link should read, "University of Calgary video on 'How Mercury Causes Brain Neuron Degeneration.'"

I checked one source. I marked what seemed to be the corresponding texts in bold, and underlined the possible conflicts: mercury from amalgam vs. health care facilities; total mercury emissions vs. releases in wastewater; 53% of total emissions is about the UK only; one-third seems to be specific for Canada.
The Dental amalgam controversy article also presents the 53% and one third as global figures ... DS Belgium ( talk) 02:17, 17 October 2011 (UTC)
It may be worth noting (if reliable sources can be identified) that while many dentists now prefer to use only composite materials, many dental insurance plans will only pay for amalgam (because it is cheaper). Perhaps the "controversy" article says this, but it does seem to be relevant to this article as well. A source that indicated exactly how much cheaper would be useful, as would recent data on the relative use of amalgam and composite fillings in some large English-speaking country. 121a0012 ( talk) 07:55, 18 December 2011 (UTC)
I removed a paragraph from the controversy section stating that Norway, Denmark and Sweden have banned silver amalgam. This was an unsourced statement that cited a Long Island dental office in the business of removing these fillings. The domain name was laserfillings dot com. The controversy section is much better put together without it. Bananabananabanana ( talk) 09:26, 31 December 2011 (UTC)

Hi. Im Danish and last week I had an amalgam filling done here in Denmark. The Reuters article referred to as stating that amalgam filling is illegal/banned in Denmark (and Scandinavia) is wrong and superficial at best. If anyone want to inform on the laws about amalgam filling in Scandinavia, please refer to these specific laws. It should be easy if they exists. RhinoMind ( talk) 13:05, 11 October 2013 (UTC)
PS. In my case, a large (and old) amalgam filling in my
Mandibular first molar broke and it was repaired with amalgam. I was not too happy about refilling with amalgam, because of the health issues, but rethinking the situation I feel ok about it, for these reasons:
RhinoMind ( talk) 13:05, 11 October 2013 (UTC)
Studies have shown that the amount of mercury released during normal chewing is extremely low. A tuna fish sandwich releases the same amount of mercury as 3-5 amalgam fillings.
There is an article for Dental amalgam controversy, then Amalgam (dentistry) and Mercury poisoning.
Wikipedia tries not to repeat the development of content. Persons wishes to write about the dental amalgam controversy should do so at the article for that, and not at the articles for amalgam or mercury poisoning. Those articles should link to the "dental amalgam controversy" article, so that discussion can be centralized. I am looking at these articles now and intend to merge all content from amalgam and mercury poisoning to the controversy article, then make sections in each of those articles based on the lede of the controversy article.
My intent is to direct people to the controversy article if they want to read about the controversy. Please discuss my doing this only at Talk:Dental_amalgam_controversy, not on the talk pages of the other articles, to the extent that it is reasonable to have this conversation in one place. Blue Rasberry (talk) 19:58, 15 July 2014 (UTC)
There doesn't seem to be anything on this page about what amalgam does that makes it useful to dentists other than a passing reference to its durability. I wonder if someone could see their way to adding a bit near the top for laymen to get an introduction to how amalgam works in dentistry, from a top down view. I only learnt that it sets for example from a heading; the contents of that heading are incomprehensible or at least irrelevant to the "pub quiz" level of knowledge I was hoping for (in addition to the detail, which I'm sure useful for those with a greater understanding of the topic). — Preceding unsigned comment added by 2.99.123.42 ( talk) 20:50, 31 March 2015 (UTC)
As far as talking about setting reaction ,it might took more than 6years to understand that too for some well experienced person in dentistry.Even though I am a dentist,it took me 6yrs to understand it properly...What I thought was it should not take more than 15 minutes to understand ,thats why I explained only setting reaction in lay man language which will help other dentists to understand and thus they can easily explain to their collegues.The hardest and confusing part of amalgam is to understand setting reaction.And talking about basic functions,then why dont you attempt to edit by taking complete review from internet.? sidsandyy ( talk) 07:35, 11 May 2015 (UTC)

This is my first venture into a dentistry related article on Wikipedia, and I am surprised how poorly written it is. I mean, take just the opening lines:
An amalgam is an alloy composed of mercury and other metals.[1] Dental amalgam is produced by mixing liquid mercury with an alloy made of silver, tin, and copper solid particles.[1] Small quantities of zinc, mercury and other metals may be present in some alloys.[1] This combination of solid particles is known as amalgam alloy.[1]
which contains multiple contradictions and inconsistencies. An amalgam is an alloy that includes mercury, so it is misleading to state that "mercury ... may be present". Then, it is redundant (and wrong) to define something as an "amalgam alloy", which is redundant (and wrong)! If I knew something about this topic, I would be prompted to completely rewrite it, but at this point I just find it completely untrustworthy - and I especially distrust anything in the sections about controversy over toxicity.

Several years ago, a dentist in Switzerland told me that the technique of using amalgam for fillings was no longer even taught in Swiss dental schools. The only procedure concerning amalgam fillings still taught is how to remove them safely and replace them with something else. It is not correct, however, that dentists switched entirely to resin ("plastic") fillings. Metal inlays (mainly gold) are still used because they have better wear characteristics than other materials. Ceramic jacket crowns are also used. Longitude2 ( talk) 09:21, 25 March 2020 (UTC)
"current amalgam alloy consists of silver (40%), tin (32%), copper (30%) and other metals.[11]" Sum (40+32+30) exceeds 100%; please resolve.
