What's that in my pasta?

I was eating a nice tuna roe pasta in Genoa when I felt something like a pistachio shell in my mouth. It was one of the gold crowns on my molar that had popped off.

I just got done with the dentist this morning. He had to replace the filling that the crown was sitting on top of and then re-glue the crown back on. My tongue still feels like a potato.
