Root Canal Treatment after Crowns
Any time tooth structure is removed; root canal treatment is a possibility. Generally, if your tooth had an existing filling or crown, or if decay is deep, then the odds increase. Some studies have shown that between 6% and 25% of all teeth need root canals before or after crown prep or cementation. There is always a separate fee for root canal treatment.
If you need a root canal treatment before or after the crown is delivered, it may or may not be possible to remove if. If removal cannot be done, an access hole is drilled in the top of the crown through which the root canal treatment is preformed. The access hole typically will not ruin the crown and it later can be filled with tooth- colored dental material, although the filling may be visible. Sometimes the entire crown must be replaced.
