Unfortunately, I bet they wouldn't state that amalgam is unsafe, at least publicly. They would be bashed by the ADA and other dentists if they did.
I looked up the ADA statement on amalgam, and it contains obvious and gross distortions. Remember that amalgam consist dominantly of mercury, then read this from the wonderful ADA:
"Dental amalgam (silver filling) is considered a safe, affordable and durable material that has been used to restore the teeth of more than 100 million Americans. It contains a mixture of metals such as silver, copper and tin, in addition to mercury, which chemically binds these components into a hard, stable and safe substance." Who would ever guess from that statement that amalgam is actually 50% mercury?
Consider these weasel words: ""the small amount of mercury released from amalgam restorations, especially during placement and removal, has NOT BEEN SHOWN to cause any adverse health effects."
"Not been shown" is a long way from "proven safe," especially when we are talking about low-level toxic exposure. Especially when you consider that we can't ethically or legally do real controlled tests on people. Our wonderful professional medical associations and FDA bureaucrats also told us non-steroidal anti-inflammatory drugs were safe, and Drs. still Rx tons of them as the primary weapon against arthritis, even though they quite often cause intestinal bleeding, sometimes of catastrophic degree. They also have other significant risks.
I think it was our new dentist that did say the amalgams weren't safe. I was going to raise questions about the years of lies but thought better of it.
My complaint about all this is that yes we were lied to about this, and, when they started using the white filling, our dental insurance didn't cover the white fillings, calling them 'cosmetic', and saying they didn't last as long as the amalgam. I don't know if dental insurance now covers the white filling or not since we no longer have dental insurance.
