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.
