There's a lot of talk on the internet that mercury amalgam fillings are toxic and should not be done. In the 20 years since my first cavity I've only received metals-free composite fillings. My current dentist informs me that composite fillings are qualitatively better, while disregarding the health concerns with amalgams. This has made me wonder, what percentage of fillings performed today are done with mercury amalgam? In other words, I have a suspicion that it is an increasingly irrelevant problem.
I've tried the basic Google searching for an answer, but results on the topic are obfuscated by reports concerning the percentage of mercury in fillings, rather than percentage amalgam fillings administered.
I did find:
According to the American Dental Association (ADA), more than 100 million silver-amalgam fillings are placed in American mouths each year.
...
As a sign of the times, in 1999, around 86 million composite restorations were placed in the United States, as against 71 million amalgam restorations.

I'd like something more current though. Plus, I don't know if the sum of those figures represents the total.

Some recent estimated numbers recently were:
45% of all dental restorations world wide (Heintze 2012),
50% of all American fillings
But
Many developed nations have virtually eliminated dental amalgam. Dental amalgam use is banned in Sweden and Norway; only used in 3% of all dental restorations in Japan and Finland; 5% in Denmark; 10% in the Netherlands, Switzerland, and Germany; and 20% in Singapore.

So if the usa tends towards the way Sweden, Japan, and others have moved, my suspicion that it's an increasingly irrelevant problem is correct. I guess I need to see if there's a downward trend in amalgam use. My 1999 data point from a comment above may indicate it's been a steady half-and-half for 20 years.

@fredsbend If amalgam is a problem (FDA says no, I say yes), then you also have to look at a lot of older teeth, or remnants of those. You might say it is decreasing as a problem, but quoting Angus Young in reverse, "it's a long way from the top, if you wanna irrelevancy" (have to improve the metrics for these lyrics, though)

Well, replacement is different than installing, and comes with unique risks. Without widespread replacement, decreases in installs will result in decreases in prevalence, albeit slowly. Health concerns aside, filling longevity seems the biggest argument among dentists now, with many suggesting that composites and resins simply don't last as long. Personally, I don't mind having to replace a few fillings every 10 years, instead of every 30.

@fredsbend "Longer lasting" is against resin-based, and pales a bit against gold or ceramics. The kickers are cost and tradition, ease-of-use. And I haven't seen a global (re-)view on resin vs amalgam that takes tooth survival longer term into account (amalgam needs more removal of healthy enamel). What I have seen is the hazmat gear dentists wear when removing amalgam in a living patient…

Removal often requires vaporizing the amalgam. I'd wear a hazmat too. That's the main reason I'd think twice before removing my own (I fortunately have none anyway).

@fredsbend If amalgam is a problem (FDA says no, I say yes), then you also have to look at a lot of older teeth, or remnants of those. You might say it is decreasing as a problem, but quoting Angus Young in reverse, "it's a long way from the top, if you wanna irrelevancy" (have to improve the metrics for these lyrics, though)

Well, replacement is different than installing, and comes with unique risks. Without widespread replacement, decreases in installs will result in decreases in prevalence, albeit slowly. Health concerns aside, filling longevity seems the biggest argument among dentists now, with many suggesting that composites and resins simply don't last as long. Personally, I don't mind having to replace a few fillings every 10 years, instead of every 30.

@fredsbend "Longer lasting" is against resin-based, and pales a bit against gold or ceramics. The kickers are cost and tradition, ease-of-use. And I haven't seen a global (re-)view on resin vs amalgam that takes tooth survival longer term into account (amalgam needs more removal of healthy enamel). What I have seen is the hazmat gear dentists wear when removing amalgam in a living patient…

Removal often requires vaporizing the amalgam. I'd wear a hazmat too. That's the main reason I'd think twice before removing my own (I fortunately have none anyway).
