Quick answer
Many root canal appointments take about 60 to 90 minutes, though timing depends on the tooth, the infection, and your treatment needs.
What you'll learn
Most appointments are completed in one visit
For many teeth, root canal treatment can be completed in a single appointment lasting roughly one to one-and-a-half hours. Front teeth often have fewer canals, while molars can take longer because their anatomy is more complex.
Why treatment time varies
The number and shape of canals, the level of infection, symptoms, and whether a tooth needs additional restoration all affect the timeline. In some cases, your dentist may recommend more than one visit to achieve the best outcome.
Plan for the restoration
After treatment, a tooth often needs a permanent filling or crown to protect its remaining structure. Your dentist will explain the treatment sequence and what is appropriate for your specific tooth.
