Can a root canal be done in single sitting?
The last thing you want to hear is that you need a root canal. And the idea of scheduling several visits with your dentist just adds insult to injury. So you’re wondering: is it possible to do a root canal in one visit?
Yes! While some root canals do require more than one visit, many can be done in one. The condition of your tooth, extent of infection, and other factors your dentist will assess before determining whether single sitting root canal treatment is right for you. Read on to learn how root canals in a single visit are done, who qualifies for single visit treatment, and why your dentist may advise you to stretch your root canal out over two appointments.
Like many procedures, root canal treatment has an unfair reputation. While they may have been lengthy and unpleasant decades ago, modern technology has allowed dentists to treat more patients in one visit than ever before. Single visit root canals are possible for the majority of cases thanks to rotary instruments, advanced imaging, and effective disinfection protocols. Learn where you stand ahead of time so you can go into your appointment with accurate expectations instead of outdated horror stories.
Quick Answer
A root canal can be completed in one visit provided that the infection is not extensive and the canal system of the tooth is easily cleaned and sealed during one appointment. This type of treatment is referred to as single sitting or single visit root canal treatment. There have been studies comparing single visit RCT to multiple visit RCT and concluded that pain relief and healing were essentially the same between single and multiple visits although healing was slightly better in the studies that used single visit treatment at both 6 months and 12 months.
What Happens During a Single Sitting Root Canal
A single sitting root canal covers the same core steps as a multi-visit one, just completed back to back in one appointment:
Local anaesthesia: The tooth and surrounding area are numbed completely before any work begins
Access opening: The dentist creates a small opening in the tooth to reach the infected pulp
Cleaning and shaping: Infected tissue is removed and the canal is cleaned and shaped using rotary files
Disinfection: The canal is irrigated with an antibacterial solution to clear out remaining bacteria
Obturation: The cleaned canal is filled and sealed with a biocompatible material, usually gutta-percha
Sealing the tooth: A filling or temporary crown closes the access opening, with a permanent crown often placed at a later visit if needed
With modern rotary instruments and reliable apex locators, this entire sequence often takes 45 to 90 minutes for a single tooth, depending on how many canals it has.
Who Is a Good Candidate for Single Sitting RCT
Your dentist will usually recommend single sitting treatment if:
The tooth has limited or no active infection at the time of treatment
The canal anatomy is straightforward, without unusual curves or extra canals
There's no heavy swelling or pus discharge from the tooth
You don't have a medical condition that limits how long you can keep your mouth open
You're not dealing with acute pain from a flare-up that needs to settle first
When Multiple Visits Are Needed Instead
A single visit isn't right for every case. Your dentist may recommend spreading treatment across two or more appointments if:
The tooth has a persistent infection with pus or drainage that needs time to clear
The canal system is complex, such as in molars with curved or extra canals
You have a history of trauma to the tooth with an unclear infection pattern
You have TMJ issues that make it hard to keep your mouth open for an extended procedure
You're highly anxious about treatment and would benefit from a shorter, less intense visit
Neither approach is objectively better for every patient. Your dentist decides based on what they find during the initial examination and X-rays, not a fixed rule.
Single Visit vs Multiple Visit RCT: What Research Shows
One study that compared post-operative pain and healing rates between single-visit and multiple-visit root canal therapy found no significant difference in pain at 24, 48, and 72 hours following treatment. However, it did find greater incidence of complete healing in the single visit group at both 6 and 12 months. Another study concluded there is a practical benefit to doing everything in one visit: it eliminates the possibility of bacteria re-entering the canal between appointments because the tooth is disinfected and sealed on the same day instead of being temporarily filled and left for a week or two.
Is Single Sitting RCT Painful?
You should feel no pain while the procedure is being done, as local anaesthetic is used to numb the area throughout. You may experience some slight soreness afterwards for a day or two which should be relieved by taking an over-the-counter painkiller recommended by your dentist. Some have complained of similar soreness following multiple appointments for RCT, so having your treatment completed in one visit will not leave you with more pain.
Like any dental work, there are certain precautions you can take to allow for quick recovery regardless of treatment approach. Don't chew on the tooth being worked on until you are certain that any temporary filling or crown has hardened. Avoid anything too hard for the first day or two of recovery. Maintain your normal dental hygiene regimen and continue to brush and floss around the treated area rather than avoiding it. Pain that worsens instead of subsiding over the course of a few days, or any swelling should prompt a return visit to your dentist.
Benefits of Single Sitting Root Canal Treatment
Fewer appointments: One visit instead of two or three saves time off work or other commitments
Lower risk of recontamination: The canal is sealed the same day, reducing the chance of bacteria getting back in between visits
Faster relief: You leave with the infection addressed rather than waiting on a temporary filling
Comparable or better healing: Studies show outcomes at least as good as multi-visit treatment, sometimes better

Frequently Asked Questions
1. How long does a single sitting root canal take?
Most single-visit procedures take 45 to 90 minutes per tooth, depending on the number of canals and how complex the anatomy is. Molars generally take longer than front teeth.
2. Is single sitting root canal treatment safe?
Yes, it's a well-established approach used widely today. Research comparing it to multi-visit treatment has found similar or better healing outcomes, provided the case is suited to a single visit.
3. Can all teeth be treated with a single sitting root canal?
No. Teeth with active infection, complex canal anatomy, or a history of trauma often need multiple visits so the dentist can monitor healing before sealing the canal permanently.
4. Will I need a crown after a single sitting root canal?
Often, yes, particularly for back teeth that handle heavy chewing pressure. Your dentist will usually place a filling immediately and discuss a crown at a follow-up visit if the tooth needs extra reinforcement.
5. Does a single visit root canal hurt more than a multi-visit one?
No, studies comparing the two approaches have found similar levels of post-treatment discomfort. Mild soreness for a day or two is normal with either method.
