A standard root canal procedure typically takes between 60 and 90 minutes for a front tooth and up to two hours for a molar. Some complex cases may require two separate appointments to complete treatment. Any mild tenderness afterward is common, temporary, and easily managed. If you need gentle, efficient care, our team provides advanced root canal treatment in a calming environment designed to ease dental anxiety.

Finding the Best Dentist for a root canal makes a significant difference in both comfort and long-term outcome. Our dentists are licensed by the Royal College of Dental Surgeons of Ontario (RCDSO) and use modern tools to complete root canal therapy efficiently while keeping you completely numb. Whether you arrived with a sudden toothache or a referral from your family dentist, you will receive a thorough assessment and clear explanation of the time required for your specific tooth.
To make scheduling even easier, you can reserve your appointment through our Online Booking portal. We keep response times fast and always accommodate emergencies when possible. Our practice is equipped with CEREC same-day crown technology, so if your root canal tooth needs a permanent crown, you can often have the entire treatment completed in a single visit.
What Is a Root Canal?
A root canal, clinically called endodontic treatment, removes infected or inflamed pulp tissue from the inside of a tooth. The pulp contains nerves and blood vessels that can become damaged due to deep decay, cracks, repeated dental procedures, or trauma. When bacteria invade the pulp chamber, it can cause a periapical abscess and significant pain. The root canal procedure cleans, shapes, and seals the root canal system, saving the natural tooth and preventing extraction.
This treatment is routine, predictable, and no more uncomfortable than getting a filling when performed by a skilled Dentist in Woodbridge. Modern local anesthetics ensure the tooth and surrounding area are completely numb before any work begins.
How Long Does a Root Canal Take by Tooth Type?
Treatment length varies primarily by tooth location and complexity. Below is a typical breakdown:
- Front teeth (incisors and canines): 60–90 minutes
These teeth usually have a single straight canal with easy access. - Premolars (bicuspids): 70–90 minutes
Premolars often have one or two canals and moderately complex anatomy. - Molars: 90–120 minutes or more
Molars have two to four canals, often curved or narrow, and are located farther back in the mouth, requiring more precise instrumentation.
A molar root canal may sometimes be divided into two appointments if extensive infection or calcified canals are present. At Columbus Dental Centre, we maximize the work completed in each visit so you spend less time in the dental chair without compromising quality.
Factors That Influence Root Canal Duration
Beyond tooth type, several clinical factors can affect how long your appointment will last:
- Severity of infection: An abscess or large area of periapical radiolucency may require a medicated interim dressing and a second visit to ensure complete healing before sealing the canals.
- Number and curvature of canals: Extra canals, sharp curves, or calcified (narrowed) canals make mechanical cleaning and shaping more time-consuming.
- Retreatment: Removing old root canal filling material and posts, and addressing missed canals, adds significant time. Retreatment cases are often completed over two appointments.
- Same-day restoration: If you are receiving a CEREC same-day crown immediately after the root canal, total in-office time will be longer because the tooth is prepared, scanned, and restored in one session.
- Patient cooperation and comfort: Taking short breaks or needing extra anesthesia for a highly anxious patient can slightly extend the appointment.
At our office, every case begins with a digital radiograph and a discussion of the expected timeline, so there are no surprises.
Step-by-Step Root Canal Procedure
Understanding what happens during a root canal helps set realistic time expectations. Here is the typical sequence:
- Examination and imaging
A periapical X-ray or cone-beam CT scan assesses the root anatomy and infection. The dentist reviews findings with you and answers any questions. - Local anesthesia
A profound numbing agent is administered. You should feel pressure but no sharp pain. Additional anesthetic techniques are used if the tooth is “hot” with pulpitis. - Rubber dam isolation
A thin sheet of latex or non-latex material isolates the tooth, keeping it dry and free from saliva bacteria. - Access opening
A small opening is created through the chewing surface of a posterior tooth or the back of an anterior tooth to reach the pulp chamber. - Cleaning and shaping
Tiny flexible instruments (endodontic files) remove diseased pulp tissue, bacteria, and debris. The canals are simultaneously irrigated with antimicrobial solutions. - Obturation (filling the canals)
Once the canals are clean and dry, they are sealed with a biocompatible material called gutta-percha and a sealer to prevent reinfection. - Temporary or permanent restoration
A temporary filling is placed if a future crown appointment is needed, or a permanent filling/core buildup is completed if a CEREC crown is delivered the same day.
Does a Root Canal Hurt?
The fear of root canal pain is one of the most persistent myths in dentistry. In reality, the procedure relieves the severe pain caused by pulp inflammation. With modern local anesthesia, patients typically feel no more discomfort than during a routine filling. Our team serves as a Top Dentist in Woodbridge by ensuring you are comfortable from the moment you sit in the chair.
After the numbness wears off, the tooth may be slightly tender to biting for a few days. This is due to inflammation in the surrounding tissues and is managed with over-the-counter analgesics. Any lingering discomfort should be reported to your dental office for evaluation.
Recovery and Aftercare
Post-treatment instructions are simple but important:
- Avoid chewing on the treated side until the permanent restoration is placed.
- Maintain excellent oral hygiene, brushing and flossing normally but gently around the area.
- Take any prescribed or recommended pain relievers as directed.
- Attend your follow-up appointment for a permanent crown or filling without delay.
A restored, infection-free tooth can function normally for decades with proper care and regular checkups.
Restoring Your Tooth After a Root Canal
A tooth that has undergone root canal treatment often needs a full-coverage crown to protect it from fracture. Because the tooth is no longer vital, it can become brittle over time. Our clinic offers CEREC Same Day Crowns Woodbridge using digital scanning and in-house milling. This means you can have the root canal and final ceramic crown completed in one extended visit—no messy impressions, no temporary crown, and no second appointment.
For patients who value a natural-looking smile, our team also includes a skilled Cosmetic Dentist in Woodbridge who ensures that crowns and restorations blend seamlessly with your existing teeth. If your root canal is on a front tooth, a customized tooth-colored crown or veneer can restore full aesthetics and strength.
When a Root Canal Becomes an Emergency
Severe throbbing pain, swelling, a pimple-like bump on the gum, or sensitivity to hot that lingers can all signal an abscess requiring urgent treatment. As a reliable Emergency Dental Clinic in Woodbridge, Columbus Dental Centre reserves daily emergency slots so you are not left waiting in discomfort. Prompt intervention can often prevent the infection from spreading and may reduce overall treatment time.

Frequently Asked Questions
Can I eat after a root canal?
Wait until the numbness completely wears off—usually two to three hours—to avoid accidentally biting your cheek or tongue. Stick to soft foods for the first day and avoid chewing on the treated tooth until your permanent restoration is in place.
How many visits are required for a root canal?
Most front teeth and premolars are completed in one visit. Molars or severely infected teeth sometimes require two visits to allow medicated dressings to work. Your dentist will let you know the anticipated number of appointments after examining your tooth.
Is a crown always necessary after a root canal?
Not always, but it is strongly recommended for posterior teeth. Molars and premolars endure heavy chewing forces and are prone to fracture after root canal treatment. Front teeth with minimal structural loss may only need a permanent filling.
How long does a root canal last?
With proper oral hygiene and regular dental checkups, a successfully treated root canal tooth can last a lifetime. The key is prompt placement of a quality final restoration and good home care.
What happens if I delay root canal treatment?
Delaying treatment allows infection to spread, which can lead to increased pain, abscess formation, bone loss, and eventual tooth loss. Timely intervention saves the tooth and typically involves a shorter, more straightforward procedure.
Conclusion
A root canal generally takes between one and two hours, depending on the tooth and complexity, and restores your oral health without extraction. Choosing an experienced, technology-forward team ensures the procedure is comfortable, efficient, and long-lasting. If you are experiencing tooth pain or have been told you need a root canal, trust a clinic with over 26 years of dedicated family and cosmetic care in the Vaughan community to guide you through every step.
