Few dental procedures have a worse reputation than the root canal — but the reality is far less scary than the myths suggest. Root canal therapy is one of the most common and effective treatments in dentistry, saving millions of teeth every year. If your dentist has recommended a root canal, here’s what you actually need to know.
What Exactly Is a Root Canal?
A root canal is a treatment used to repair and save a tooth that is badly decayed or infected. Inside every tooth, beneath the hard enamel and dentin, is soft tissue called the pulp. The pulp contains nerves, blood vessels, and connective tissue that helped the tooth grow during development. When this pulp becomes inflamed or infected — due to deep decay, repeated dental procedures, cracks, or trauma — a root canal removes the damaged tissue, cleans the interior of the tooth, and seals it to prevent further infection.
Signs You Might Need One
Common symptoms that may indicate you need root canal therapy include severe toothache that worsens when chewing or applying pressure, prolonged sensitivity to hot or cold temperatures that lingers after the source is removed, darkening or discolouration of the tooth, swelling and tenderness in nearby gums, and a persistent pimple-like bump on the gums. However, some teeth needing root canals show no symptoms at all, which is why regular dental checkups with X-rays are so important.
The Root Canal Procedure Step by Step
Modern root canal treatment is typically completed in one or two visits. Your dentist or endodontist begins by administering local anaesthesia to numb the area completely. A small protective sheet called a dental dam isolates the tooth and keeps it dry. A tiny opening is made in the crown of the tooth to access the pulp chamber. Using specialized instruments, the infected pulp is carefully removed, and the canals are cleaned, shaped, and disinfected. The cleaned canals are then filled with a biocompatible material and sealed. In most cases, a crown is placed on the tooth afterward to restore its full strength and function.
Does It Hurt?
This is the question everyone asks — and the answer may surprise you. With modern anaesthesia and techniques, most patients report that a root canal feels no different from getting a regular filling. The procedure actually relieves pain rather than causing it, since the source of your toothache — the infected pulp — is being removed. You may experience mild soreness for a few days afterward, which is typically managed with over-the-counter pain relievers.
Cost of Root Canals in Canada
The cost of a root canal in Canada varies depending on which tooth is affected and the complexity of the case. Front teeth with a single canal typically cost between $500 and $1,000, while molars with multiple canals can range from $800 to $1,500 or more. The crown that usually follows adds another $800 to $1,500. Most dental insurance plans in Canada cover a significant portion of root canal treatment, and the CDCP also includes coverage for eligible patients. Always request an estimate from your dentist before proceeding.
Root Canal vs. Extraction
When faced with a severely damaged tooth, some patients wonder whether extraction might be simpler. While pulling a tooth is sometimes necessary, saving your natural tooth through root canal therapy is almost always the preferred option. Natural teeth function better than replacements, extraction leads to bone loss over time, and replacing a missing tooth with an implant or bridge often costs more than the root canal and crown combined. Your dentist will help you weigh the options based on your specific situation.
Recovery and Aftercare
Recovery from a root canal is straightforward. Avoid chewing on the treated tooth until your permanent crown is placed, take prescribed or over-the-counter pain medication as needed, and maintain your regular brushing and flossing routine. Most patients return to normal activities the same day. Contact your dentist if you experience severe pain lasting more than a few days, visible swelling, or if your bite feels uneven after the crown is placed.
