is composite generally a safe bonding material?

[Guest guest]

I've gotten half my fillings out and am being fitted for porcelain inlays,

onlays and crowns. The dentist uses composite as the bonding adhesive. Is

there a better, ie more neutral bond than this? Too late to do the CC testing.

Also, is it possible that the " tattoos " on my gums could be silver nitrate?

There are flecks, not blobs, on the xray, the dentist said mercury would show in

a different shape than flecks, these fillings are 35 years old, could it be

silver nitrate? Should I get bone and tissue incision to get this material out

before chelation? The dentist recommended against trying. Thnx, Helen
