Hello, I am planning on getting two crowns on teeth 2 and 3. After the dentist finish the core build-up, I notice that there was a black line between the filling and the teeth. Should I be worry about it?

Black stains

It's not usually an issue. Stained dentin can be sound and strong. Your dentist tests it before completing the work.
