A toothache, sensitivity to hot or cold, or a lingering discomfort that won’t go away can lead to one of the most common dental procedures: a root canal. Many people’s first concern isn’t pain or cost, it’s time. How long does a root canal take? Will you be in the dentist’s chair for a quick half-hour, or does it stretch into an all-day ordeal? Understanding what to expect can ease your anxiety and help you plan your visit effectively.
The answer isn’t one-size-fits-all. Root canal duration depends on several factors, including the type of tooth, the complexity of the canals, whether the tooth is infected, and whether a general dentist or endodontist is performing the procedure. Let’s break down everything you need to know about root canal timing, from start to finish.
How Long Does a Root Canal Take
The duration of a root canal varies widely, but most single-root teeth, like front teeth, typically take 30 to 60 minutes, while multi-rooted teeth, like molars, can take 60 to 120 minutes or even require two visits. If you’re wondering how long does a root canal procedure take, it’s helpful to think in terms of the tooth type, number of canals, and whether there’s any infection.
For many patients, a root canal isn’t just a single procedure. Dentists often schedule multiple appointments for complex or infected teeth, which is why searches like how long does a root canal appointment take or how long does a root canal take start to finish are so common.
- Average root canal time: 60–90 minutes per tooth
- How long is a root canal appointment: usually one hour for simple teeth, longer for molars
- How long does a single root canal take: depends on the tooth and complexity
How Long Does a Root Canal Take on Different Teeth
Front Tooth Root Canal
Front teeth usually have a single canal, making them the quickest to treat. A root canal front tooth time often falls between 30 and 60 minutes. Because of the simpler anatomy, local anesthesia works efficiently, and the procedure is generally less uncomfortable.
Molar Root Canal
Molars are more complex due to multiple canals. A molar root canal time can range from 60 minutes to over two hours, depending on the tooth’s anatomy and whether infection is present. These cases sometimes require a second appointment. Patients often search how long does a root canal take on a molar or how long does a complicated root canal take because molars are more time-consuming.
Premolars
Premolars usually have one or two canals. The root canal duration for these teeth is typically 45–90 minutes.

Step-by-Step Root Canal Procedure Time
Understanding each stage of a root canal can help you visualize the time commitment and ease anxiety.
- Numbing the Tooth: Local anesthesia usually takes 5–10 minutes to fully take effect.
- Cleaning and Shaping the Canals: This is the most time-consuming part. Dentists remove infected tissue and shape the canals for filling. Time varies by complexity—typically 20–60 minutes.
- Filling and Sealing: Once cleaned, the canals are filled with gutta-percha and sealed, which usually takes 10–20 minutes.
- Temporary or Permanent Crown Prep: If a crown is needed, preparation and placement add another 20–30 minutes, often scheduled for a separate visit.
Searches like root canal procedure steps, root canal process time, cleaning root canal time, and filling root canal time all relate to these individual stages.
Factors That Affect How Long a Root Canal Takes
Complexity and Infection
Not all root canals are straightforward. Infection or complicated canal anatomy increases the procedure time significantly. An infected tooth may require additional cleaning, irrigation, or even multiple appointments. Searches like how long does an infected root canal take or root canal with infection time reflect patient concerns about extended duration.
Dentist vs Endodontist
Endodontists specialize in root canal treatment, often completing procedures faster than a general dentist. While a general dentist may take longer on molars or complex teeth, endodontists can streamline the process using advanced tools.

Single vs Multiple Appointments
While many root canals are completed in a single visit, some require two visits, especially if there’s extensive infection or multiple canals. Patients often search one visit root canal or two visit root canal to understand scheduling. Complex cases may involve multiple appointment root canal treatment, particularly with molars.
Pain, Comfort, and Anxiety During a Root Canal
Root canal procedures have a reputation for pain, but modern dentistry and anesthesia make them much more manageable than people fear.
- Does a root canal hurt? Pain during the procedure is minimal due to local anesthesia.
- How painful is a root canal on a scale of 1–10? Most patients rate pain between 2 and 4, and discomfort afterward is usually mild.
- Pain after root canal can last 1–3 days, typically managed with over-the-counter pain relievers.
For anxious patients, knowing the exact root canal time can reduce stress. Techniques such as deep breathing, sedation options, and explaining the steps help minimize root canal anxiety.
Recovery Time After a Root Canal
After a root canal, understanding recovery is key for comfort and planning:
- Numbness: Local anesthesia wears off in 2–4 hours. (how long does numbness last after root canal)
- Eating: Avoid chewing on the treated tooth until numbness is gone. Soft foods are recommended initially (eating after root canal timing).
- Full Recovery: Mild sensitivity may last 1–3 days, but most patients return to normal function quickly. (root canal recovery time)
Comparing Root Canal Duration with Other Procedures
Many patients wonder how a root canal stacks up against other dental procedures in terms of time.
Root Canal vs Tooth Extraction
A tooth extraction is generally faster, often completed in 15–30 minutes for a simple extraction. However, while extraction is quicker, it removes the natural tooth entirely. Root canals preserve the tooth and maintain your bite alignment, though the procedure takes longer. This is why searches like how long does a root canal take compared to extraction are common.
Root Canal vs Filling
A standard filling is quicker, usually 20–40 minutes, because it doesn’t involve cleaning the tooth’s inner canals. Root canals take longer, typically 30–120 minutes depending on tooth type and complexity, but they treat infection and prevent further decay.
Root Canal Including Crown
Many teeth that have undergone root canal treatment require a crown for long-term protection. A root canal including crown may take an additional 20–30 minutes for preparation and fitting during a separate visit. For some patients, the total time from start to finish may stretch across multiple appointments.

Root Canal with Anesthesia
Another consideration for timing is anesthesia. While local anesthesia is standard, some patients require sedation, which adds 5–15 minutes for preparation. Procedures with sedation or anesthesia can take slightly longer, but they make the process more comfortable for anxious patients.

How Long Does a Root Canal Take if It’s Infected?
An infection in the pulp of the tooth can complicate a root canal. Infected canals may require:
- Extra cleaning and irrigation
- Application of antibacterial medication
- Sometimes a temporary filling and follow-up appointment
For these cases, how long does an infected root canal take often extends to 90–120 minutes or more. Severe infections sometimes necessitate a second visit to ensure the canals are fully disinfected before final filling.

How Many Visits Are Usually Needed?
The number of appointments can affect total treatment time:
- One visit root canal: Possible for uncomplicated front teeth or premolars
- Two visit root canal: Often needed for molars or infected teeth
- Multiple appointment root canal: Required when retreatment or infection control is needed
Patients also search root canal same day treatment, which is usually feasible for simple, single-root teeth.

Dentist vs Endodontist Timing
Who performs the root canal can influence the duration:
- General Dentist: Experienced dentists can complete most root canals in one appointment, but complex molars may take longer.
- Endodontist: Specialists often perform root canals faster and more efficiently due to advanced tools and expertise, particularly for multi-rooted or complicated teeth.
This is why many patients search root canal at dentist vs endodontist time or specialist root canal appointment length.

Post-Procedure Considerations
After the root canal, understanding what to expect is key to comfort and proper recovery.
- Recovery Time: Most patients fully recover in a few days. (root canal recovery time)
- Numbness Duration: Typically 2–4 hours after anesthesia. (how long does numbness last after root canal)
- Pain After Root Canal: Mild tenderness can last 1–3 days; OTC painkillers are often sufficient. (how long does pain last after root canal)
- Eating After Root Canal: Avoid chewing until numbness wears off; start with soft foods. (eating after root canal timing)
Cost and Time Considerations
While the primary focus is duration, many patients also think about the cost:
- Root Canal Cost vs Time: Longer, more complex procedures often cost more.
- Insurance Coverage: Some plans cover the procedure fully, while others may require partial payment.
- How Long and How Much Is a Root Canal: Patients want to know the total commitment, both in time and money.
Planning for both factors ensures the experience is less stressful.
