According to my dentist, materials in "Noble Cast 60" a gold crown material:
56% Gold 25% Silver 4% Palladium 13+% Copper .2+% Iridium .99% Zirconium .01% Iridium Interesting, Dan - what do we know about these materials in the body? Zirconium - don't they make artificial diamonds out of that? Add a sparkle to your smile. Iridium sounds scary - and copper? Well, maybe good for your arthritis? I imagine any metal in the mouth is rather near the brain and could set up electrolytic or is it galvanic reactions? Rowena Not refusing to smile so much now! And not experiencing electric-shock teeth, either.
