If you’re scheduled for dental treatment, it’s normal to ask how long does a root canal take. Many people imagine it taking hours or being extremely painful, but modern dentistry has made root canals much faster and more comfortable. This article explains the average time a root canal takes, what affects the duration, and what you can expect during each stage of the procedure.
Average Time for a Root Canal
In most cases, a root canal takes 60 to 90 minutes.
Some simple root canals can be completed in 30–45 minutes, while more complex cases may require two appointments.
The exact time depends on several factors, including the tooth type and the level of infection.
How Long Does a Root Canal Take Per Tooth?
Front Teeth (Incisors and Canines)
-
Usually take 30–60 minutes
-
Have one root, which makes treatment faster
-
Often completed in one visit
Premolars
-
Typically take 60–90 minutes
-
May have one or two roots
-
Often completed in one visit
Molars (Back Teeth)
-
Can take 90 minutes or longer
-
Have multiple roots and canals
-
May require two visits
Molars take longer because they are harder to access and more complex.
What Affects How Long a Root Canal Takes?
Several factors influence treatment time:
-
Number of roots and canals
-
Severity of infection
-
Whether it’s a first-time or repeat root canal
-
Dentist’s experience and equipment
-
Patient comfort and cooperation
If the tooth is severely infected, your dentist may place medication inside and schedule a second visit.
Step-by-Step: What Happens During a Root Canal
1. Examination and X-rays (10–15 minutes)
The dentist examines the tooth and takes X-rays to assess damage and infection.
2. Numbing the Area (5–10 minutes)
Local anesthesia is applied to prevent pain. You may feel pressure, but not discomfort.
3. Cleaning the Tooth (30–60 minutes)
-
The dentist removes infected pulp
-
Cleans and shapes the root canals
-
Disinfects the inside of the tooth
This is the longest part of the procedure.
4. Filling and Sealing (10–20 minutes)
The cleaned canals are filled and sealed to prevent reinfection.
5. Temporary or Permanent Filling
A temporary filling is placed if a crown is needed later. Some cases receive a permanent filling the same day.
Does a Root Canal Take More Than One Visit?
Sometimes, yes.
You may need two visits if:
-
The infection is severe
-
The tooth has multiple canals
-
Additional treatment is required
Each visit usually lasts 45–90 minutes.
Is a Root Canal Painful or Long?
Thanks to modern anesthesia, most patients say a root canal feels similar to getting a filling. The procedure is not painful, and the time passes more quickly than expected.
Mild soreness afterward is normal and usually fades in a few days.
Recovery Time After a Root Canal
-
You can return to normal activities the same day
-
Numbness wears off in a few hours
-
Avoid chewing on the treated tooth until fully restored
Pain relief medication usually manages any discomfort.
Conclusion
So, how long does a root canal take?
For most people, it takes about 60 to 90 minutes, often completed in a single visit. More complex teeth may require two appointments, but modern dental techniques make the process efficient and comfortable. Understanding the timeline can help reduce anxiety and make you feel more prepared.
