Tooth has gone completely black under crown, after root canal a few years ago. Is this normal?

MR1
I had a root canal a few years ago and the crown never felt like it fitted properly. I went to have it removed and replaced last year, and the dentist found that the tooth underneath had gone completely black. He said this is nothing to worry about, but I have read it can mean the tooth is infected. My new crown covers my tooth well, but I worry about the black tooth underneath. Is this normal?
