i cannot tell by reading their site. usually germany is a good place to get products from because they are strict on what they allow. i would have to know if there are any aluminum-type fibers in it. i would be curious to know what type of metals are in it since they say it is ceramic-based (i think that is what they are saying). many metals used in making composites are mostly burnt off in the final processing. i would at least need to see an MSDS on it. your dentist has one and by law has to let you see it. if you get a copy, send it to me and i can tell you better.
yes, absolutely, you should not go to a dentist who has amalgams in his mouth.
