How Long Does A Root Canal Take?

Mar 30, 2026

Many people experience anxiety when they are told that they need a root canal. One of the most common questions that patients ask is how long the procedure will take. The good news is that contemporary dental practices have made root canal procedures shorter, more comfortable, and highly effective. In most cases, the procedure can be completed in one visit.

What Is a Root Canal Procedure?

A root canal is a dental procedure that is used to treat an infection in a tooth. When there is an infection or inflammation in the pulp of a tooth due to decay, cracks, or trauma, a dentist removes the infected pulp from inside the tooth. This way, instead of extracting the tooth, it is saved from being removed.

Average Time for a Root Canal Treatment

Generally, a root canal treatment may take anywhere from 60 to 90 minutes to complete. However, for some teeth, especially those that are more complex, it may be necessary to make two separate visits. Teeth at the front of the mouth tend to take less time because they have fewer roots, whereas teeth at the back of the mouth, such as molars, may take a bit longer because of their complexity. Your dentist will assess your tooth and advise you accordingly.

Factors That Can Affect Root Canal Duration

Several factors can influence how long a root canal procedure takes. Each patient’s situation is unique, and the tooth’s complexity significantly affects treatment time.

Tooth Location

Front teeth usually have one root canal, which means that treatment is quicker. Molars have many canals, which means more time is required.

Severity of Infection

If the infection is severe or has spread to surrounding tissues, it may take additional time for the dentist to properly clean and disinfect the tooth.

Need for Multiple Appointments

Some teeth can be treated in a single visit, while others require two visits. If the infection is severe, medication may be placed in the tooth before the next visit to help eliminate the infection.

Dental Restoration After Treatment

Once the root canal is complete, many teeth, particularly molar teeth, will need a crown to protect them. This appointment may take an additional visit.

How Long Does Numbness Last After a Root Canal?

Numbness from local anesthesia typically lasts 2–4 hours after the treatment. During this time, it is best not to eat to avoid the possibility of biting your cheek or tongue. Some discomfort or sensitivity may occur, but it will soon disappear. Over-the-counter pain relievers can ease the discomfort.

Final Thoughts

The procedure for a root canal is quite routine and only takes an hour to an hour and a half to complete. Although it does depend on the tooth and how infected it is, most people find it is much easier than they thought it would be.
