The time a root canal requires is usually 30 to 90 minutes per appointment, and most patients require one or two sessions. Teeth that have one canal, such as front teeth (canines and incisors), may take approximately 30 minutes. Premolars typically require 30-60 minutes. More canals are found in molars, and usually require 60-90 minutes and sometimes a second appointment.
Most people who delay a root canal aren’t afraid of the pain anymore; that’s taken care of by modern anesthesia. They’re unsure of how long does root canal take and scared of losing half a workday to it. For most teeth, that fear is bigger than the real time commitment. The American Association of Endodontists also states that most root canals can be completed in one to two appointments, with each appointment lasting roughly 90 minutes.
The time yours will take will depend largely on the tooth and the amount of infection. Here’s the real breakdown, tooth by tooth, plus what actually stretches a routine appointment into a longer one.
How Long Does Root Canal Take by Tooth Type?
The time needed for a root canal depends partly on which tooth needs treatment. Different teeth have different numbers, shapes, and positions of canals. Front teeth usually have fewer and easier-to-reach canals, while back teeth have more complex anatomy.
Canines and Incisors
The front teeth typically have one canal that is fairly straight, making them the fastest root canals to finish. It will take approximately 30 minutes in total for a canine or incisor.
Premolars
Premolars are located between front teeth and molars, and may have one or two canals. They usually last 30-60 minutes, depending on the shape of the canals.
Molars
Molars are the workhorses of chewing and usually have three or four canals, sometimes more. That extra anatomy means more time cleaning and shaping each one, typically 60 to 90 minutes, and molars are the tooth type most likely to need a second appointment if the infection is severe or the canals are hard to reach.
| Tooth type | Typical canals | Typical chair time |
|---|---|---|
| Canines and incisors | 1 | About 30 minutes |
| Premolars | 1-2 | 30-60 minutes |
| Molars | 3-4+ | 60-90 minutes |
So, How Long Do Root Canals Take, Start to Finish?
This is where a lot of guides get vague. The appointment itself is only part of the timeline. Most root canals will complete the treatment of the infected part of the tooth in one appointment, but most require a permanent crown following the procedure, which will be scheduled a few weeks later. So the straight answer is two times in total; once to treat the infection (sometimes twice) and then again further down the road to cap the tooth. The treatment itself typically takes an hour or so of the total time, which is usually 2 to 6 weeks from first appointment to finished tooth.
What Happens During a Root Canal Appointment
The typical root canal appointment has several key steps. This will depend on the tooth and the complexity of the case.
| Treatment stage | Approximate time |
|---|---|
| Examination and X-rays | 10–20 minutes |
| Numbing and preparation | 10–15 minutes |
| Accessing the tooth | 10–20 minutes |
| Cleaning and shaping | 30–60 minutes |
| Filling and sealing | 20–40 minutes |
| Temporary restoration | 5–10 minutes |
An appointment is typically 30-90 minutes. Molars may take longer due to the fact that they have more canals to clean and treat.
What Makes a Root Canal Procedure Take Longer Than Expected?
There are a number of factors that can cause a root canal to be longer than anticipated, particularly for more challenging teeth.
- If the infection or abscess is severe, a second visit may be needed.
- The longer it takes to clean the narrower, curved or calcified canals.
- Retreatment requires additional time to remove the old filling material.
- More breaks may be needed during treatment if the dental anxiety is high.
These factors can make the appointment last longer than the typical 30-90 minutes.
General Dentist or Specialist: Does It Change the Timeline?
Root canals can be performed by a general dentist or an endodontist, a specialist who only performs root canals. Most root canals performed at Glow Up Dentistry are performed in-house, especially on front teeth and premolars.
In some cases, such as more complicated cases, serious infections, unusual canal anatomy or retreatments, the case is referred to a specialist.
The difference in how long it takes to do a root canal does not have to do with skill; it has to do with scheduling. An in-house appointment with your regular dentist may also result in a quicker time between diagnosis and treatment, as you don’t have to wait for a referral and a new-patient appointment somewhere else.
Why Waiting Makes It Take Longer
It is generally easier and quicker to get a root canal when symptoms begin the week you schedule it than when symptoms start months later. The infection spreads if it is not treated, and the larger the infection, the longer it takes to clean, the greater the likelihood that it requires more than one visit, and the greater the risk that it will become an emergency rather than a scheduled appointment. If you are in pain now and not waiting to see, then you are in a same-day situation, not a wait-and-see situation.
After the Root Canal: Recovery and Your Permanent Crown
A root canal is used to treat the infection, but treatment is not complete once you leave the dental office. The tooth and adjacent tissue must heal, and in most instances, the tooth will need to be crowned with a permanent restoration.
Recovery Time
The mild soreness or sensitivity that most people experience after treatment lasts 2-5 days and can be treated with an over-the-counter pain reliever. It is not the same pain that got you in here to be treated in the first place, but it is more like the tenderness that you would have after any dental work.
Getting Your Permanent Crown
The temporary filling placed at the end of your root canal appointment isn’t meant to last. Most dentists will wait 2-4 weeks after the swelling has gone down and the tooth has stabilized before placing the permanent crown. This is important to do, or it can cause the tooth to crack or the temporary filling to fail.
How to Help Your Root Canal Appointment Go Faster
There are a few simple steps you can take to make your root canal appointment as smooth and efficient as possible:
- Check in early: Allows sufficient time for check-in and anesthesia.
- Talk about anxiety: Your dentist can schedule additional time or sedation, if necessary.
- Eat before: Makes you feel better after treatment.
- Please inquire about same day care: Early intervention can help avoid further complications.
These will help to minimize delays and make your appointment more comfortable.
Root Canal vs. Tooth Extraction: Which Takes Longer?
A simple tooth extraction is typically performed in the chair in 20-40 minutes, while a root canal takes 30-90 minutes.
- Extraction: 20–40 minutes
- Root canal: 30–90 minutes
- Tooth replacement: May need an implant, bridge or partial denture
The overall time of extraction may be longer, however, due to the extra procedures and healing time required to replace the missing tooth. A root canal saves your natural tooth which may be the easier choice in the long run.

Conclusion
A common question patients ask is, “How long is a root canal procedure?” Most treatments take about 30 to 90 minutes per appointment. The procedure typically lasts from 30 to 90 minutes and is usually finished in one or two appointments. This will depend on the tooth, number of canals, infection and the complexity of the case. More severe infections may require more time or a second appointment; molars may be required.
Don’t postpone an evaluation if you are having tooth pain, swelling, or sensitivity. Early treatment helps to prevent the infection from becoming more complicated and may make the treatment process easier.
Frequently Asked Questions (FAQs)
Yes, in most front teeth and for the premolars. More canals to clean means more infected teeth are more likely to require two visits, as well as more molars, because sometimes the dentist wants the infection to settle before sealing the tooth.
Yes. More severe infections will require more tissue to be removed, and sometimes a waiting period between visits for the infection to settle before the tooth is sealed. Early diagnosis will typically result in treatment in one visit.
Most people don’t. An appointment lasts about 30 to 90 minutes, and the local anesthetic effects are not felt for days, but rather within a few hours. Most patients can return to work the same day, but it is advisable to schedule this time for the afternoon to allow time to buffer the chewing on that side afterwards.
It is typically faster to extract in the chair, but a root canal preserves the natural tooth in one. Removing a tooth, rather, results in a second procedure later to replace it, which will take more total time than a root canal will.
Most dentists recommend waiting 2-4 weeks after the root canal for the tooth to settle before placing the permanent crown. The longer the delay, the greater the possibility of the tooth cracking or the temporary filling coming out.
The mild soreness usually goes away within 2-5 days. Over the next few months, the tooth and area around it continue to heal without any symptoms, but should not restrict normal activity after the first few days.
Yes, usually. There are three or four canals in molars, and only one in a front tooth, so there’s more to clean and shape. It will take about 60-90 minutes for a molar compared to about 30 minutes for a canine or incisor.
Treatment for the infected tooth typically requires one or two visits in a week or two. The permanent crown appointment (two to four weeks later) and the whole process takes approximately two to six weeks.
