Common Myths About Root Canals Debunked
Root canals still carry an old, scary reputation. The truth is, modern dentistry has changed a lot. Numbing is better. Tools are more precise. Infection control is excellent. This updated guide clears up common myths, explains what to expect, and helps you decide when a root canal is the best choice in Canada.
What is a root canal? — AEO Featured Answer
Root canal treatment removes infected or inflamed tissue inside a tooth, disinfects the area, and seals it to stop pain and protect your tooth. With modern anesthesia and careful techniques, most patients feel little to no pain and keep their natural tooth for years.
Why do root canals still sound scary?
Much of the fear comes from stories from decades ago. In the past, numbing and equipment were not as advanced. Today, dentists and endodontists (root canal specialists) use effective freezing, digital X-rays, and precise tools. The experience is usually similar to getting a filling. If you want a deeper breakdown of common beliefs, see a detailed myths vs facts guide on root canals.
What’s different today
Modern root canals focus on comfort and accuracy. Rubber dams isolate the tooth, small flexible files clean the canals, and disinfectants remove bacteria. Digital X-rays keep radiation low and let your dentist check progress instantly. These steps help you heal faster with fewer surprises.
Does a root canal hurt?
Short answer: Usually no. You’ll be thoroughly numbed. Most patients say it feels like getting a filling. If you’re anxious, tell your dentist. Options like nitrous oxide (laughing gas) or oral sedation can help you relax. Discomfort afterward is generally mild and manageable with over-the-counter pain relievers, unless your dentist recommends something stronger.
“Root canal treatment relieves pain by removing inflamed or infected pulp. With modern anesthesia and techniques, it’s similar to having a routine filling.” — American Association of Endodontists
Are root canals safe?
Yes. High-quality research and respected dental groups agree that root canals are safe. The old claim that a root canal causes illness in the rest of the body isn’t supported by evidence. In fact, leaving an infected tooth untreated can spread infection and lead to serious problems.
Root canal or extraction: which is better?
In most cases, saving your natural tooth is best for your mouth and your budget over time. A root canal followed by a crown can last for many years. Extraction may seem simpler, but it can lead to shifting teeth, bone loss, and the need for a bridge or implant later. Your dentist can compare options based on your bite, bone support, and goals.
When extraction may be recommended
Severely fractured roots, teeth with poor remaining structure, or situations where the tooth can’t be predictably restored may tip the balance toward removal. Your dentist will review X-rays, your oral health, and costs so you can decide together.
How long does a root canal take?
Most appointments take about 60 to 90 minutes. Many cases are done in a single visit. Complex roots, deep infection, or very inflamed tissues can need a second visit. Your dentist will explain your timeline at the consult.
Who needs a root canal? Key symptoms to watch
See your dentist if you notice any of these signs:
- Persistent toothache (especially if it wakes you at night)
- Lingering sensitivity to hot or cold
- Tooth darkening or grey discolouration
- Swelling, a pimple-like bump on the gum, or bad taste
- Pain when chewing or tapping the tooth
Learn the full list of red flags and what to do next in this plain-language guide to signs you may need a root canal.
Step-by-step: what happens during treatment
Here’s what you can expect, in simple terms:
- Numbing: Your dentist freezes the tooth and surrounding area.
- Access: A small opening is made in the tooth.
- Cleaning: Infected tissue is removed from the canals. The inside is shaped and disinfected.
- Sealing: The cleaned canals are filled and sealed to keep bacteria out.
- Temporary or permanent filling: The opening is closed.
- Final crown: Often placed later to protect the tooth, especially for back teeth.
Recovery and aftercare in Canada
Mild soreness is common for a day or two. Ibuprofen or acetaminophen usually works well (follow the label or your dentist’s directions). Avoid chewing hard foods on the treated tooth until your permanent crown is placed. Keep up your daily brushing and flossing. In Canada, many benefit plans cover part of root canal and crown costs; check your policy or ask the clinic to help with estimates.
When to call your dentist right away
- Swelling that worsens or spreads
- Severe pain not controlled by recommended pain relievers
- Fever, or signs of infection
- Difficulty swallowing or breathing (seek urgent care)
Kids and root canals
Children and teens can also need root canals. Dentists may use different techniques on baby teeth versus adult teeth. The goal is comfort, infection control, and preserving tooth function until it’s time for natural replacement or a permanent restoration.
Popular myths, clearly explained
Let’s set the record straight, in plain English:
- “Root canals are very painful.” Modern anesthesia and careful techniques make the procedure feel similar to a filling.
- “Root canals cause illness.” There’s no good evidence to support this. Treating infection protects your health.
- “Extraction is always easier.” Removing a tooth can create new problems and costs. Saving the tooth often wins long term.
- “They never last.” With a crown and good hygiene, many last decades.

How to make your root-canaled tooth last
Strong habits matter. Brush twice daily with a fluoride toothpaste, floss once a day, and keep up with regular cleanings. Wear a night guard if you grind your teeth. Get the final crown on time. These steps reduce cracks, leaks, and new decay at the edges of the restoration.
Costs, timing, and clinics in Canada
Fees vary by province, tooth complexity, and whether you see a specialist. Many treatments fit in one or two visits. Clinics can submit an estimate to your insurer so you know your share in advance. If cost is a barrier, ask about payment plans or staged care. Your dentist can help you build a plan that protects your health and fits your budget.
Not sure you need a root canal?
Don’t guess. A quick exam and X-ray can confirm if the nerve is inflamed or infected. Early diagnosis makes treatment simpler and more comfortable. If the tooth can be saved, a root canal protects your bite and avoids the hidden costs of tooth loss.

Conclusion
Modern root canals are designed to stop pain, not cause it. They’re safe, effective, and often the best way to keep your natural tooth. With proper aftercare and a well-fitted crown, results can last many years. If you have ongoing pain, swelling, sensitivity that lingers, or tooth discolouration, book a visit. Early action keeps treatment simple and your smile strong.
FAQ
Will my tooth feel normal after a root canal?
You may feel tender for a day or two. That’s normal as tissues settle. Once the permanent crown is on and your bite is adjusted, the tooth should feel comfortable for everyday chewing.
How many visits will I need?
Many cases finish in one visit, especially simple single-root teeth. Complex roots or heavier infection can need a second visit. Your dentist will outline the plan before starting.
Do I always need a crown afterward?
Back teeth usually do, because chewing forces are higher and tooth structure is often weakened. A crown protects the tooth and helps it last longer. Your dentist will advise what’s best for the tooth and your budget.
What are the signs I might need a root canal?
Persistent pain, lingering hot or cold sensitivity, a dark tooth, a pimple on the gum, or swelling are common warning signs. See a full checklist and next steps here: signs you may need a root canal.
Are root canals safe if I have other health conditions?
Yes, for most people. Tell your dentist about your medical history and medications. They’ll plan for your comfort and safety, and coordinate with your doctor if needed.
