Few dental procedures have sparked more fear than the root canal - but the reputation is outdated. At Invisalign Smile Centre, root canal treatment is designed to save your natural tooth with precision and comfort, using advanced rotary technology and digital imaging to clean and restore infected tooth roots in a painless, single or multi-visit procedure.
Signs you might need a root canal
A root canal is usually needed when the soft tissue (pulp) inside a tooth becomes infected or inflamed - commonly from deep decay, a crack, or trauma to the tooth. Common signs include a persistent toothache, sensitivity to hot or cold that lingers, pain when chewing or biting, or swelling and tenderness in the surrounding gum. If any of these sound familiar, it's worth getting the tooth examined rather than waiting.
Why it doesn't have to be the ordeal people expect
Two things make the difference: advanced rotary technology, which allows for more precise, efficient cleaning of the root canal system, and digital imaging, which lets us see exactly what we're treating before and during the procedure. Together, this is what allows the treatment to be painless rather than the outdated experience most people picture - and it's why it's one of the procedures we point to most often when patients tell us they're anxious about treatment.
[PENDING YOUR CONFIRMATION - see note below]: Local anesthesia is used to numb the area completely before treatment begins, so you shouldn't feel the procedure itself.
What actually happens during treatment
While every case is a little different, root canal treatment generally follows the same path: an initial evaluation (often with imaging) to confirm the tooth needs treatment, numbing the area, creating a small access point in the tooth, cleaning out the infected or damaged tissue from inside the root canal, and sealing the space before placing a filling - or, in some cases, a crown to protect the tooth long-term.
Why save the tooth instead of removing it?
Removing an infected tooth might sound simpler, but it isn't the better option in most cases. A missing tooth can lead to shifting of the surrounding teeth, bite problems, and bone loss in the jaw over time - and replacing it later, with an implant or bridge, is typically more involved and more costly than treating and keeping the natural tooth now. A root canal exists specifically to avoid that chain of events.
One visit or several - planned around your case
Root canal treatment here is done as a single or multi-visit procedure, depending on what your specific case needs. There's no one-size-fits-all timeline - it's planned around your tooth, not a fixed script.
What to expect afterwards
It's common to have some mild soreness or sensitivity in the treated tooth for a day or two afterwards - this is generally manageable and improves quickly. As with most dental procedures, it's a good idea to avoid chewing on the treated side with very hard or sticky foods until you've healed and any recommended filling or crown is in place.
Part of a complete approach to your smile
Root canal treatment is one piece of the broader range of services available at Invisalign Smile Centre - alongside general dentistry, cosmetic treatments, and Invisalign. If a root canal is recommended during a routine check-up, you're treated by the same team, in the same clinic, rather than being referred elsewhere.
Frequently Asked Questions
Is root canal treatment really painless? Yes - advanced rotary technology and digital imaging are used specifically to keep the procedure painless, whether it takes one visit or several.
How do I know if I need a root canal? Common signs include a persistent toothache, lingering sensitivity to hot or cold, pain when chewing, or swelling near the tooth - if you notice these, it's worth getting examined.
Will a root canal save my natural tooth, or will I still need an extraction? The goal of root canal treatment is to save your natural tooth - cleaning and restoring the infected root rather than removing the tooth.
Why not just remove the tooth instead? Removing a tooth can lead to shifting teeth, bite problems, and bone loss over time, and replacing it later is usually more involved than saving it now.
How many visits does a root canal take? It depends on your case - root canal treatment here is done as either a single-visit or multi-visit procedure.
What happens to the tooth after treatment? Root canal treatment is designed to preserve the tooth's strength and appearance, not just remove the source of pain.
Can I have a root canal if I'm anxious about dental visits? Yes - this is one of the treatments we most often recommend for anxious patients, since the painless technique addresses the fear directly.
