Cerec is not metal but zirconium or perhaps some vanadium mixed in. It is a ceramic and it would be an effort on the part of anyone to add lead to it.

Problem with some of the gold from China is radioactivity. Some gold is unusable due to being found close to uranium. Unless you check it with a dosimeter you never know!!

Thanx for the info.

If you click the link in OP, you will see that crowns from China may contain lead and a woman had an adverse reaction.

I don’t really want anything in my mouth made in China, anyway. I don’t trust them.
