Thanks for everyone's responses so far.


There are quite a few sources on the internet that say that nickel is still used:

"Nickel is added to the metal in braces (and crowns) so they don't rust. Here we call it stainless steel.":

"More than 75% of the crowns placed today are nickel":

"Typically, what dental labs use to make crowns and bridges is nickel":

http://www.newlifejournal.com/10-02/askpatton_10_02.htm

"Crowns can be all metal, porcelain fused to metal (PFM), or all ceramic. Metals include gold alloy, other alloys (palladium) or a base-metal alloy (nickel or chromium). The all-metal or PFM crowns are stronger and are better choices for back teeth."

Since most of my crowns and bridges date back to the 70's and 80's, I'm thinking it's even more likely they used metal back then.
