I have a zirconium porcelain crown on one of my front teeth. It's newly placed, only a few days. The area where the crown meets the gum is dark. The dentist said it is because my underlying tooth is dark. I had a root canal 10 years ago on that tooth, so it is dark. However, when he had created the temporary crown, I did not that issue. There was no darkening. I think the permanent crown may be shorter that the temporary crown. Please help me understand what the problem is, thank you
