Thanks for your kind reply.
So probably the white I see is cement rather than dentin? Is there an
easy way for me to tell?

Okay, just worried that it meant he couldn't get the temp to fit (due to
not removing enough dentin), so they wouldn't be able to make the
permanent crown thin enough.

Probably I misused the term "plastic". Now that you mention it, I think
it was silicone. It was blue and soft ("rubbery") and semi-opaque like
silicone automotive sealant. It had a slight bitter taste.
