While most general dentists are trained to perform root canals, they may refer patients to endodontists because the procedures are time-consuming and require precision. Endodontists specialize exclusively in root canals and have advanced equipment allowing them to complete the procedure faster with less discomfort for the patient. It is ultimately up to the patient whether to see their general dentist for a potentially less expensive root canal or an endodontist for quicker treatment using specialized tools, though cost is often the primary factor in the decision.
