How long does it take to get the actual crown delivered and put in?

It comes down to the lab. If the lab is local it may have a faster turnaround, but the average is 2 weeks. If planned in advance, this can be less than a week, but unless there is CAD CAM milling in office, that is about as fast as one can expect. 

Placing the new crown should not be more than 10 days max. In some cases we had to deliver the final permanent crown the next day, which is very possible. Of course the ceramists usually charge an extra rush charge depending on the complexity of fabricating the permanent crown! Usually less than 10 days there is extra charges that may apply.

In my office we use CEREC to make crowns in a single visit.  Since your dentist does not have this technology, it is necessary to take a mold, place a temporary crown, and have a dental lab make the crown.  The process usually takes 2-4 weeks.  Your dentist should be able to tell you.  Anything longer than 4 weeks is too long.
