Filling materials & ingredients

[Cwodavids]

Hi,

I have quite a few amalgams and a gold crown that need replaced and was wondering about the different materials and what they contain. I am considering the following in my research:

-Resin
-Zirconium
-Porcelain
-Glass ionomer

Is there somewhere that I can find a list of the ingredients and/or the safety data sheets for them please (I am USA based)?

Any help is greatly appreciated as I have found limited info online and my dentist is not particularly helpful unfortunately.
