I had a crown put on a tooth.  After several days part of the crown came apart and I had to go back to the dentist.  He drilled on the crown part of the tooth and filled it.  I asked if that was a crown and he said "technically, it was a double-up".  He did not charge me any money because I had paid for a crown originally.  What is a "double up"?  thank you.

Dear Richard:
I am sorry, but I have never heard of such a thing as a "double up", there is no such dental term or procedure.  If your crown was just inserted several days ago and a piece of the porcelain broke, most dentists would replace the crown right away.  If the crown is repaired with a filling material, chances are that the material will break off in the future.
You must call your dentist and understand what exactly happened.
Best of luck,
Dr. Zev Kaufman.
