Typically a same day procedure.
Cost is based on for a root canal without an abscess.

WHAT TO DO:
ROOT CANAL THROUGH AN EXISTING CROWN:
If the dentist determines that the crown won't come off (or at least not easily or predictably), then they'll have to drill the hole (access cavity) right through it to perform the treatment.
There are several types of crown construction, and the strength characteristics of each kind will be affected differently when it is drilled through.
Drilling a hole through an all-metal (gold) crown probably won't significantly affect its overall strength characteristics.
Creating an access cavity through a PFM restoration likely won't significantly affect its overall strength either.
But doing so may affect the integrity of it's porcelain covering (outer shell), possibly resulting in chipping or fracture especially in the region immediately around the access cavity. (This chipping effect could compromise the integrity of a restoration placed later as a repair for the hole, see "filling placement" below.)
More extensive porcelain fracture is possible too. In some cases this may only be of cosmetic concern. But if the loss is large enough it may present a functional problem too.
In comparison to types of crowns that contain metal, the process of creating an access cavity through an all-ceramic ("porcelain") one presents the least predictable outcome. Doing so can result in serious concern about restoration strength or damage (such as microcrack formation) that may ultimately lead to failure.
Just as with PFM crowns, ceramic chipping immediately around the access cavity itself is commonplace
