A root canal procedure typically takes between 30 minutes and 2 hours, depending on the complexity of the case and the tooth involved. Here is a breakdown by tooth type:

• Canine and incisor teeth (front teeth with one root): Usually take about 30 to 60 minutes.
• Premolars (teeth between canines and molars with one or two roots): Typically require 60 to 90 minutes.
• Molars (back teeth with up to four roots): Are the most complex and time-consuming, often taking 90 minutes or more

Most root canals are completed in one or two visits. If a dental crown is needed after the root canal, that usually requires an additional appointment lasting about 60 minutes

. The procedure includes numbing the area with local anesthesia, removing infected tissue, cleaning and disinfecting the canals, and sealing the tooth. Despite common fears, the procedure itself should not be painful due to effective anesthesia, and any discomfort is usually from the infection before treatment

. In summary, expect a root canal appointment to last from half an hour to up to two hours, with molars on the longer end due to their complexity.
