How Long Does a Root Canal Take?

If your dentist recommends a root canal, your first question is usually “How long will this procedure take.”

Most root canals take between 60 to 90 minutes, depending on the type of tooth, the severity of infection, and whether a crown is placed during the same appointment.

Average Root Canal Duration

Tooth Type Average Duration
Front teeth 30 to 60 minutes
Premolars 60 to 75 minutes
Molars 90 minutes or more

Molars contain multiple canals, making treatment longer than front teeth which typically have only one canal.

Step-by-Step Root Canal Timeline

Step Description Estimated Time
Examination and X-rays Evaluation and imaging to determine infection severity 15 to 30 minutes
Local anesthesia Ensuring comfort throughout the procedure 5 to 10 minutes
Tooth preparation Accessing the pulp and placing isolation 10 to 15 minutes
Cleaning and shaping Removing infected tissue and disinfecting canals 30 to 60 minutes
Filling and sealing Sealing canals with permanent material 20 to 40 minutes
Final restoration Temporary filling or permanent crown placement 10 to 20 minutes

Average chair time ranges from one to one and a half hours.

One Visit vs Two Visit Root Canal
