4. Crown or bridge abutment teeth may require root canal treatment
After being crowned, teeth may develop a condition known as pulpitis or pulpal degeneration. The tooth or teeth may have been traumatized from an accident, deep decay, extensive preparation for the crown or bridge, or from other causes. It may be necessary to do root canal treatments on the affected teeth. If teeth remain sensitive for long periods of time following crowning, root canal treatment may be necessary. Infrequently, the tooth or teeth may abscess or otherwise not heal, which may require root canal treatment, root surgery or possibly extraction.
