My mother has a lot of those and they keep crumbling and she has to have them changed. She swallowed a few of them. She also suffer from neurological diseases and fibromyalgia.
That those are in fact made of mercury is blowing my mind right now.
I'll advise her to get her mercury levels checked out.
Quoting:
> The debate over the safety and efficacy of amalgam has raged since time immemorial. In recent times, it has reached such a feverish pitch that it seems to drown out all sounds of reason. Amalgam has served the dental profession for more than 165 years. Incidents of true allergy to mercury have been rare and attempts to link its usage with diseases like multiple sclerosis and Alzheimer’s disease have not been significantly proven, although there may be some association between amalgam restorations and oral lichenoid lesions.
> Marshall, in his review on dental amalgam, summed it up appropriately: “if some reported values of Hg release are extrapolated to clinical life times, the entire restoration could lose its Hg in short time. For example, a 500 mg amalgam restoration contains approximately 200–250 mg of Hg, and the entire quantity of Hg would be lost in 10,000 days if the Hg was released at the rate of 25 ?g/day. This estimate of release is of the order of magnitude reported in some studies of vapour release”.
The real crux of the issue is that there are safer effective alternatives. So even if we call the risk "low," it is a needless risk. It only a matter of "when" not "if" these filings are against safety regulations.
The anti-dentites won.
edit: internet searching about on this apparently shows that the price difference should not be that much??? Two different dentists want me to pay about $250+ more per tooth for non-amalgam fillings. Madness!
How do I know it was the amalgam fillings? Because that was my only exposure, and because it turned out my jaw bones were very damaged - exactly were there had been amalgam fillings. It was discovered not by x-ray, several OPGs never showed anything. But when I was to get an injection into the buccal mucosa the needle went right into the bone (that's really not supposed to happen, you can't penetrate bone with a small needle used for a mucosa injection). The doctor checked and this happened in all the places where I had had amalgam fillings. He then injected DMPS in those places. A year later, and after the jaw bones had been very active (but in a positive way) the needle didn't go in anywhere any more. To this day there is (decreasing) activity in my jaw bones, and I still take chelators that have an effect right there (jaw bone).
But please, go ahead and downvote anyone who says something about amalgam fillings. I actually have a background in medical topics, from anatomy, physiology to (of course) bio chemistry, and I read quite a few studies. The lead situation was so bad that politicians actually went to action to do something about it, worldwide. Mercury is far more toxic than lead (and, according to some LD study I once found on PubMed, together about a thousand times more toxic than either lead or mercury alone). Yes, pieces of amalgam are not the problem, they go right through. And as others have said, insertion and even more so removal - with a drill creating heat which creates vapor (no matter how much you cool with water, by then the vapor already exists) - are the worst parts. I had had a few fillings removed while I was a student. Only recently, two decades later, did I connect the dots, why back then I had a huge "almost asthma" allergy almost overnight, as well as huge problems finding sleep, strange thoughts, and big problems with some joints that didn't seem to have any observable reason. The removal was without protection, the removal of the last fillings a few years ago, when I hoped I had found the problem (I did not know, amalgam removal and chelation was an experiment because I could not find anything else, and boy was I proven correct), was with good protective measures that I think worked (I didn't get worse then I already was at the time).
Here is something to consider: What happened when I started DMPS chelation was something that according to doctors doing that kind of treatment is not uncommon, so much so that I was told that might happen before it happened. The initial values went down quickly and linearly - but after a few DMPS treatments my symptoms suddenly jumped. Turned out that the amount of excreted mercury had also jumped (tripled). From then on my body became "active". All kinds of crazy stuff happened, for a long time (it's still not quite over in the jaw area). It seems that the body is overwhelmed at some point and is no longer able to excrete everything. Maybe the spikes of insertion and/or removal of amalgam fillings contribute, too much at once. After the first year I took chelators because it still helped, but it was no longer necessary for excretion, my body had become pretty active. Maybe somebody whose body can deal with the spikes, or who never experiences them, has less trouble continuously getting rid of the mercury that is released from the fillings.
Sooo many questions, and I made soooo many interesting observations. Too bad it's impossible to talk about it, even anonymously on the Internet, because for some reason this topic raises the emotions of sooo many people. That the subject is present on so many websites of the esoteric kind is because it's next to impossible to talk about it in normal circles. My insurance always paid every little thing, even the most stupid and ridiculous and useless stuff - but when I finally send them a bill that mentioned "mercury" and "DMPS" (chelator) they suddenly refused. IT was a trigger word. They had paid for dozens of doctors (that one year when everything escalated, I went to many doctors with the many issues I had, from gastroenterologist to psychologist), now, the one thing that actually worked, and which was very cheap(!), they refused. It's insane. Same here - somebody mentions the trigger words (mercury, amalgam), the comment is voted down immediately. By whom actually? Are there so many prominent toxicologists reading this?
I don't think so. Even a normal MD would not know much about it. I've actually seen this: When I go to a talk from a doctor specialized in lung disease and someone in the audience asks about something not the lung the doctor is very careful not to say anything, because it's not their specialty. Strange, everybody (including non-doctors) has a strong opinion when it comes to the subject of chronic mercury poisoning through amalgam fillings.
