I just had a root canal/crown put in next to an old crown (#2 new & #3 old.) I seem to have the feeling you get when foil touches your fillings. It's between the two teeth. Can there be some sort of a metal reaction between the two? The old crown is pretty old. Idk what they used on that. I was told the #2 new crown is titanium.
