If your dentist has advised you of a root canal, one of the first questions you may ask is: how long does a root canal take? Dental procedures can be daunting, and if you don't know what to expect, it may overwhelm you. Fortunately, root canals nowadays are much quicker and more comfortable than most would imagine.
This guide explains the average timeframe of a root canal procedure, what happens at each stage, and how much time you’ll need from start to finish.
What Is a Root Canal?
A root canal is a dental treatment that addresses an infection or inflammation within the pulp of the tooth, which is the part with nerves and blood vessels. Rather than extracting the entire tooth, your dentist extracts the infected tissue, disinfects the canals, and fills the tooth to preserve it.
Root canals are routine, very successful, and usually the best method for alleviating pain while preserving your natural tooth.
How Long Does a Root Canal Take on Average?
On average, a root canal is approximately 60 to 90 minutes.
- Straightforward cases (front teeth): 30–60 minutes
- More complicated cases (molars with multiple canals): 90 minutes or longer
- One visit vs. two visits: Most root canals take place in one visit, but some take two visits, depending on the infection and restoration involved.
So, when you ask "how long do root canal take?" the truth is: it varies depending on the tooth, the infection, and your dentist's style.
Root Canal Timeline: Step by Step
Here's what to expect with the procedure and how long each step typically takes:
Consultation & Diagnosis (30–60 minutes)
- Exam and X-rays
- Discussion of treatment options
Anesthesia (15–30 minutes)
- Local anesthetic numbs tooth and area around it
Isolation of Tooth (5–10 minutes)
- A dental dam protects the tooth from drying out and getting dirty
Opening the Tooth (10–20 minutes)
- Dentist makes a small opening to access the pulp
Cleaning & Shaping Canals (30–60 minutes)
- Infected tissue is cleaned out, and canals are sterilized
Filling the Canals (20–40 minutes)
- Canals are filled with a biocompatible substance
Temporary or Permanent Filling (5–15 minutes)
- Temporary filling might be used if future visit will be necessary
Final Restoration (30–60 minutes, if not done previously)
- A crown or permanent filling covers and strengthens the tooth
Recovery Time Following a Root Canal
- Same day: You're normally back to your regular activities.
- Mild discomfort: Possible for a few days, treatable with over-the-counter pain medication.
- Long-term success: Root canal-treated teeth can last a lifetime if proper oral hygiene and follow-up care are practiced.
Key Takeaway
So how long is a root canal? Generally, budget around one to two hours in the dentist chair. Front teeth are faster, and back teeth take longer since they have more canals.
Knowing the time frame should make you feel better and prepare you for the procedure. Keep in mind, a root canal does not just get rid of the pain but also saves your own tooth—an investment in your future oral well-being.
