If your dentist has just told you that you need a root canal treatment, you might feel anxious. But here is the truth: The World Health Organization’s 2026 guideline on oral health care confirms that minimally invasive treatments are now the global standard, making procedures like root canals more predictable and comfortable than ever before. A root canal treatment is simply a way to remove infected pulp from inside your tooth, clean the space, and seal it to prevent reinfection. Without it, a deep cavity or crack can lead to abscess, bone loss, and even systemic illness. Galerie Dentaire Soleil offers this procedure with digital microscopes and pain‑free protocols at their Montreal dental center.
When Do You Actually Need a Root Canal?
Not every toothache requires a root canal. You may need one if you experience:
- Spontaneous throbbing pain that wakes you up at night.
- Prolonged sensitivity to hot or cold (lingering for more than 30 seconds after the stimulus is removed).
- Swelling or a pimple‑like bump on your gum near the sore tooth.
- Tooth discolouration (grey or dark yellow) indicating nerve death.
- A cracked or chipped tooth that exposes the inner pulp.
The symptoms indicate that the bacteria have entered the pulp chamber, which is the living tissue that houses blood vessels and nerves. If left untreated, the infection can go to the jawbone, and you stand a chance of losing the tooth altogether. A root canal treatment removes only the diseased tissue, leaving the outer shell intact.
Why Choose a Root Canal Over Extraction?
Most patients are usually quick to say, “Just pull the tooth!” They think that an extraction is cheaper and faster, but it actually causes problems that last for a long time:
- Missing teeth cause adjacent teeth to shift, leading to bite collapse, difficulty chewing, and even headaches.
- Additionally, the replacement of an extracted tooth with an implant or bridge costs 3 to 5 times more expensive than the root canal and crown.
- Natural tooth roots stimulate your jawbone, preventing bone resorption. Once a tooth is pulled, you lose that stimulation.
A root canal treatment saves your original tooth, so you avoid dentures, implants, or bridges. At Galerie Dentaire Soleil, a trusted dentist montreal residents rely on, the entire procedure is completed in one or two visits, followed by a permanent crown. Our Montreal dental clinic uses 3D imaging to map every tiny canal even those that are unusually shaped.
What Happens During the Procedure? (Step by Step)
- Diagnosis and anaesthesia – Your dentist takes X‑rays or a CBCT scan. Local anaesthetic numbs the tooth and the surrounding gum completely.
- Isolation – A rubber dam (a small sheet) isolates the tooth to keep it saliva‑free and sterile.
- Access and cleaning – A tiny opening is made through the chewing surface. Ultrasonic files clean the canals and remove bacteria.
- Medication and filling – An antibacterial solution is placed, then the canals are filled with a biocompatible material called gutta‑percha.
- Temporary restoration – A temporary filling seals the opening until a permanent crown is made.
Afterwards, you may have mild soreness for 2–3 days – similar to a deep muscle bruise. Over‑the‑counter ibuprofen usually resolves it. Most people return to work or school the next day.
The Global Context: Why Root Canals Remain Essential
According to the Journal of Endodontics (January 2026 issue), a study of 263 cracked teeth treated with root canal therapy reported an overall success rate of 82.9% and a survival rate of 89.7% with a mean follow-up of 40.3 months. The estimated 2-year survival rate reached 99.2% . For teeth with favourable crack patterns (stages I–III), success rates ranged from 78.9% to 98.3% . These findings demonstrate that when performed early, root canal treatment has an excellent prognosis.
Why Delaying Treatment Is Dangerous
Some people wait months because they “don’t feel pain anymore”. That’s a red flag it often means the nerve has died completely, but the infection is still active. Without treatment, the bacteria can:
- Form a dental abscess (a pocket of pus) that erodes bone.
- Spread to your sinuses (sinusitis of dental origin) or, in rare cases, to the heart or brain.
- Causes a life‑threatening condition called Ludwig’s angina (swelling of the floor of the mouth that blocks the airway).
At the first sign of persistent tooth pain or gum swelling, visit a Montreal dental clinic like Galerie Dentaire Soleil. They offer same‑day emergency exams and can often start the root canal treatment immediately if needed.

Frequently Asked Questions
Ques1. Does a root canal treatment hurt more than a filling?
Ans: No. With modern local anaesthetics, the procedure feels identical to getting a deep filling. The old reputation for pain came from techniques used 30+ years ago.
Ques2. How long does a root canal take from start to finish?
Ans: A front tooth or premolar often takes 30–60 minutes. A molar with three or four canals may take 90 minutes. If you need a crown afterwards, add a second appointment of about one hour, two weeks later.
Ques3. Can I drive myself home after a root canal?
Ans: Yes, because only local anaesthesia is used (no general anaesthesia or sedation that impairs driving). You may feel a bit of numbness in your lip or cheek for 2–3 hours, but your reflexes and judgment are completely normal.
Ques4. What happens if I never get a root canal on an infected tooth?
Ans: The infection will not go away on its own. It will either (a) form a painful abscess, (b) silently destroy bone around the root tip (seen on X‑ray), or (c) spread to other parts of your body, requiring emergency hospitalisation and IV antibiotics.
Ques5. Is a root canal covered by Quebec’s RAMQ dental insurance?
Ans: RAMQ only covers root canals for children under 10 or adults on social assistance. Most private workplace plans cover 50–80% of the procedure. Galerie Dentaire Soleil provides a clear cost estimate before starting, and they accept most major insurance plans.
