I kept putting off the dentist visit, hoping the pain would go away. But when it started hurting just to chew toast, I knew something was wrong. The dentist told me I needed a root canaland honestly, my first thought wasn’t about the pain, it was how long does a root canal take? I just wanted to know if I’d be stuck in that chair for hours or if I could get back to work the same day.
If this question has been on your mind, you’re in the right place. This post breaks down exactly how long a root canal takes from start to finish, whether it’s your first visit, second appointment, or full recovery. We’ll explain factors that influence the timing, what to expect during the procedure, and tips for organizing your day. Let’s make it simple so you can feel more prepared and less stressed.
What Is a Root Canal?
A root canal is a dental procedure used to treat infection or inflammation inside a tooth’s pulp to the soft tissue which contains nerves and blood vessels. If not treated, this condition may cause intense pain, the formation of abscesses, or tooth loss. A root canal saves the tooth by removing the damaging pulp, cleaning the inside, and sealing it.
So, How Long Does a Root Canal Take?
General Answer
Root canal procedures typically last from 30 to 90 minutes.
One Appointment or Two?
- Simple root canal: Often completed in one visit, 30 to 60 minutes.
- Complex cases: May require two visits, each lasting 60 to 90 minutes.
Time Breakdown
| Step | Average Time |
| Exam & X-rays | 10 to 15 minutes |
| Anesthesia & Isolation | 5 to 10 minutes |
| Pulp Removal & Cleaning | 20 to 40 minutes |
| Shaping & Disinfection | 10 to 20 minutes |
| Filling the Canals | 10 to 15 minutes |
| Temporary or Permanent Filling | 5 to 10 minutes |
Total Estimated Time: 30 to 90 minutes, which varies based on the tooth and procedure complexity.
Factors That Affect Root Canal Duration
Every root canal is unique, and several variables can impact how long the procedure takes:
Tooth Type
- Front teeth (incisors, canines): 30 to 45 minutes
- Premolars: 45 to 60 minutes
- Molars: 60 to 90 minutes
(more roots = more time)
Severity of Infection
Severe infections, abscesses, or inflammation may require extra cleaning or medication, often extending the treatment or requiring a second appointment.
Number of Root Canals
Molars can have up to four canals, while front teeth usually have one. More canals = longer cleaning and shaping.
Dentist vs Endodontist
General dentists may take longer than endodontists, who specialize in root canals and often complete them faster.
Your Medical History
Patients with dental anxiety, limited mouth opening, or pre-existing health conditions may need extra time or care.

What is the Recovery Time After a Root Canal?
- Numbness lasts 2 to 4 hours.
- Most people return to work the same day.
Full Recovery
- Mild soreness may last (1 to 3 days).
- Do not chew on that side until your crown has been fitted.
Final Restoration
If a crown is required, plan for a follow-up appointment one to two weeks afterward. Placing the crown takes about 30 to 60 minutes.
Bonus: How Long Does a Root Canal Cost?
While not directly related to time, many people ask this together:
- Front teeth: $300 to $900
- Molars: $700 to $1,500
- With crown: Add $500 to $1,500
Dental insurance often covers (50 to 80%) of the cost.
Final Thoughts
A root canal usually takes 1 to 2 hours, depending on the tooth and how complex the infection is. Molars often take longer because they have more canals, while front teeth are usually quicker. The procedure is far less painful than most people expect, thanks to modern anesthesia. If your dentist recommends one, remember that the short time spent in the chair can save your tooth and prevent much bigger problems later.
