US dentists have used fillings containing mercury.
Not that it’s the same thing, but it might raise a few eyebrows if the public were educated.

Mercury (Amalgam) were usually in a tooth. A crown goes over the whole tooth and contacts the gums, therefore in contact with blood/tissue. I wouldn’t lower your eyebrows, and when you do, it won’t matter anyways.
Fear sells very well, scary movies, big foot, UFOs and Nessy.
For a reality check go to FDA.gov and read about the types of filling material available including silver amalgam and you will not be so afraid. Sorry, can not help you with the other scary items.

Who uses leaded gasoline any more?
A buddy of mine is a partner at a dental lab in KC. I’ll have to ask him about this.

American dentists have been using mercury tainted fillings for generations. I think that’s why I’m getting a root canal job every 6 months now.
Yep, blame the dentist. This is joke, right?
I have had so many fillings in my mouth since I was 6 (1957)....I should be dead, if mercury is a problem....(seems I have problem teeth.)
What proportion of that is lead?
Shouldn't be too hard.
The other question is, once the metal core is exposed, what substances which you eat will increase the solubility of the lead? Lead will generally form insoluble precipitates, but that didn't save the Romans.

They could be. My boyfriend’s dentist talked him into choosing porcelain bonded to gold, saying that the regular metals aren’t good for teeth! I have to investigate this claim. I just laughed at him when he told me.
If you ever need a crown go to a dentist who makes his own. You get your crown the same day. It is wonderful. They also look and fit better.
You would think someone would have come up with a titanium crown by now. Coat it with titanium dioxide and it stays white forever ... and it will never get sunburned, either.
Quarter ounce max - 7 grams?
What proportion of that is lead?
210 ppm = .21mg/g x 7 = 1.47mg, assuming you can leach all of it out before it gets replace once the core is exposed.
Allowed occupational exposure = 40ug/dl.
Average adult blood volume = 6L (600dl)x40ug/dl = 24000ug/1000 = 2.4mg.
Let's think about that. How long will it take that crown to "leach" that 210 parts per million? How long does it take a crown to dissolve in your mouth? Is this really a lead poisoning hazard, or just a lot of innuendo that creates the perception. Public service, or fearmongering sensationalism?
What happened ot Rome after they built lead lined aqaducts? They went crazy, having sex orgies, going on eating binges, and they fell. They fell. Lead makes one crazy.
