Root Canal Retreatment

Cost of Root Canal Treatment

Root Canal Treatment is a procedure to save teeth by removing the nerve space inside a tooth and replacing it with a filling material (gutta percha). Root canals are charged based on the number of canals (ranging from 1 to 4 or more), as well as other complicating factors (such as difficult access, exceptional anatomy, calcified canals or retreatment). Therefore, the cost of root canal treatment can range from $713 to 1593. The codes relevant to root canal treatment in the Ontario Dental Association’s Suggested Fee Guide appear as follows:
