The Truth About Root Canals: A Calgary NW Dentist Separates Myth from Fact

Root Canals Are Not What Most People Think

Root canals are one of the most misunderstood dental procedures — and that misunderstanding keeps many patients in unnecessary pain. The truth is that a root canal does not cause pain; it relieves it, often providing relief from the intense, throbbing discomfort caused by an infected or severely damaged tooth. With modern anaesthesia and technique, most patients are genuinely surprised at how comfortable the procedure really is.

What Actually Happens During a Root Canal?

Understanding the procedure takes away most of the fear. A root canal — formally called endodontic treatment — treats the soft tissue inside your tooth called the pulp. The pulp contains nerves, blood vessels, and connective tissue. When it becomes infected or inflamed (due to deep decay, a cracked tooth, or repeated dental trauma), it must be removed to save the tooth and eliminate infection.

Here is what to expect, step by step:

• Local anaesthesia is applied so you feel no pain during the procedure.
• Your dentist creates a small access opening in the crown of the tooth.
• The infected or damaged pulp is carefully removed using fine instruments called endodontic files.
• The root canals (the narrow channels inside the tooth roots) are cleaned, shaped, and disinfected.
• The canals are filled with a biocompatible material called gutta-percha to seal them.
• A dental crown is typically placed over the tooth afterward to restore its strength and function.

The entire process usually takes one to two appointments, depending on the complexity of the case.

Common Root Canal Myths — Debunked

Myth 1: “Root canals are extremely painful.”

This is the biggest myth of all. Root canals are performed under local anaesthetic, meaning the tooth and surrounding tissue are completely numb throughout the procedure. Most patients report that the discomfort is no worse than having a filling placed. The real pain comes from the infection itself — the root canal is what ends it.

Myth 2: “It is better to just pull the tooth.”

Saving a natural tooth is almost always the preferred option. Tooth extraction leads to a gap in your smile that, if left unfilled, causes neighbouring teeth to shift, affects your bite, and can lead to bone loss in the jaw. Replacing a missing tooth with an implant or bridge is also significantly more expensive than root canal treatment. Whenever possible, keeping your natural tooth is the better long-term choice for your oral health and your wallet.

Myth 3: “Root canals cause illness.”

This claim originates from thoroughly debunked research from the early 1900s and has no basis in modern dental science. Major health organisations — including the Canadian Dental Association — confirm that root canal treatment is safe. In fact, leaving an untreated dental infection is the real health risk, as oral bacteria can spread to other parts of the body if the infection is not addressed.

Myth 4: “Root canals kill your tooth.”

Technically, removing the pulp means the tooth no longer has its nerve supply, but the tooth remains very much alive in your mouth. It stays anchored in the jaw by the surrounding periodontal ligament and continues to function normally. With a proper crown and good oral hygiene, a root canal-treated tooth can last a lifetime.

Myth 5: “You only need a root canal if you are in pain.”

Not necessarily. Some cases of pulp necrosis (death of the pulp tissue) cause no obvious pain at all, particularly in the early stages. This is why regular dental examinations and dental X-rays are so important — your dentist can detect infection or damage before it becomes a dental emergency.

What If You Are Anxious About the Procedure?

Dental anxiety is completely understandable, and it should never stop you from getting the care you need. Options like IV sedation dentistry can make any procedure — including a root canal — feel effortless. You will be in a deeply relaxed, comfortable state throughout, with little to no memory of the appointment afterward. Ask your dentist whether sedation is right for you.
