Root canal therapy is a dental treatment that saves teeth that are severely decayed, infected, or damaged. When the tooth pulp — the innermost layer containing nerves, blood vessels, and connective tissues — becomes infected due to bacteria or trauma, it can lead to intense pain and even tooth loss if left untreated.
Looking for relief from tooth pain or infection? At North York Smile Centre, we specialize in Root Canal Treatment in North York, offering expert endodontic treatment to restore your smile, comfort, and oral health. Our team is dedicated to providing advanced, patient-centred care in a relaxing environment, ensuring that even the most anxious patients feel at ease.
The purpose of a root canal is to remove the infected or inflamed pulp, relieve pain, and prevent the infection from spreading. It’s often the best way to save a natural tooth rather than opting for extraction and replacement options like bridges or implants. Infected pulp left untreated can cause abscesses, bone loss, and systemic issues.
The inner pulp chamber and root canals are cleaned, shaped, and filled using biocompatible materials to seal off any pathways that bacteria could use to re-enter. By sealing the tooth, root canal therapy preserves the tooth’s outer structure, allowing it to function normally.
Identifying early signs of tooth infection is crucial for avoiding severe complications. Here are the most common root canal symptoms to watch for:
Persistent toothache: Pain that lingers or intensifies, especially when chewing, is a major red flag.
Swelling or tenderness: Inflammation in the gums surrounding a specific tooth can indicate underlying infection.
Darkening or discolouration: A tooth turning grey or dark brown could signal pulp death due to trauma or infection.
Lingering sensitivity: If sensitivity to hot or cold doesn't fade quickly after the source is removed, the pulp may be inflamed or dying.
Fear of the unknown is a common reason people delay getting root canals. Here's a detailed look at what happens during a root canal procedure at Smile By Design:
We begin with digital X-rays or 3D scans to get a clear picture of the tooth’s internal structure. This helps locate the infection and assess how many canals are involved — some teeth have up to four.
A local anesthetic is administered around the tooth and surrounding tissue. You’ll remain awake but pain-free. Sedation options are available for those who need extra comfort or deal with dental anxiety.
Once the tooth is numb, we create a small opening in the crown to access the pulp chamber. The infected or damaged pulp tissue is removed using tiny, precise instruments.
The empty canals are thoroughly cleaned using antimicrobial solutions. They are then shaped with fine tools to ensure they’re ready for filling. This step is vital for removing all bacteria and preventing reinfection.
Once cleaned, the canals are filled with a rubber-like material called gutta-percha. This seals the canals, and a temporary or permanent filling is placed to close the opening.
In most cases, especially if the tooth is a molar or has lost significant structure, we recommend placing a dental crown. The crown restores strength, function, and appearance, making the tooth look and feel completely natural.
It’s one of the most common questions we hear, and the answer is reassuring: root canals aren't painful — they relieve pain.
The discomfort people associate with root canals usually comes from the infection itself — not the treatment. After your visit, mild soreness may last a couple of days but is typically managed with over-the-counter medications.
Choosing root canal therapy over extraction offers a range of long-term benefits for your oral and overall health. It’s not just about saving a tooth — it’s about maintaining your quality of life.
Keeping your tooth is always preferable to a prosthetic, both functionally and aesthetically.
Removing the infected pulp prevents the bacteria from damaging the surrounding bone or adjacent teeth.
Extracted teeth can lead to shifting, bone loss, and a misaligned bite over time.
Eliminating infection means you can eat, speak, and smile without pain.
Knowing how to care for your tooth after treatment ensures faster healing and long-term success.
You may experience mild discomfort for a few days post-treatment. This is normal and part of the healing process.
Understanding the cost of a root canal in North York helps you make an informed decision.
Most dental insurance plans cover part of the cost. Our clinic offers flexible payment plans and direct insurance billing to make affordable dental care accessible to all our patients.
When you need a root canal, you want to trust your smile to the best. Here’s what makes us a top choice for root canals in North York:
A root canal procedure usually takes 60–90 minutes. Some complex cases or molars with multiple canals may require two visits to ensure thorough cleaning and sealing.
Not always. While front teeth can sometimes function well with just a filling, a crown is strongly recommended for back teeth. These teeth handle more pressure from chewing and are more prone to cracking without additional protection.
With proper oral hygiene and regular dental check-ups, a root canal-treated tooth can last decades, often a lifetime. The key is to get a permanent restoration, like a crown, soon after the procedure.
Yes. The main alternative is tooth extraction, followed by options such as a dental implant, a bridge, or a partial denture. However, these solutions can be more invasive and expensive in the long term. Root canal therapy preserves your natural tooth and is usually the preferred option.
Risks are minimal but can include:
That’s why choosing a skilled provider, like the team at Smile By Design, significantly reduces these risks and ensures the best outcome.
Humanizing the dental chair experience, Dr.Robert Eisen, and his right hand gal Bessie were extremely professional, considerate, and reassuring. I am in awe of the care and warmth these two delivered during my quick one hour dental surgery. Cool, Calm, and service with a Smile!
