Not bad for a cheap costume prop. All it is is a folded piece of metal painted gold, but it's a decent quality material and it didn't make my fillings ache when I wore it (big plus!).
I shaved it down to fit the tooth that I needed it for and filled it with denture cream...didn't have any problems!
It's a pretty decent costume piece as long as you're okay with doing a little bit of modification to it yourself.
