Root Canals: Myths vs. Reality

Root canal therapy has one of the worst reputations in dentistry. But the truth is, a modern root canal is a routine, relatively comfortable procedure that saves teeth and relieves pain - often dramatically. Let's look at the most common myths and what actually happens.

Myth #1: Root Canals Are Extremely Painful

This is the most widespread myth, rooted in outdated experiences from decades past. Today, root canals are performed under effective local anaesthesia, making the procedure no more uncomfortable than getting a cavity filled. In fact, because the procedure removes infected nerve tissue, most patients feel significant relief from toothache after treatment - not more pain.

Myth #2: It's Better to Extract the Tooth

Keeping your natural tooth is almost always the better option. Extraction leads to bone loss in the jaw, shifting of surrounding teeth, and the need for an implant or bridge to fill the gap - which is more invasive and expensive than a root canal. Natural teeth function better than any replacement, and root canal therapy lets you keep yours for many more years.

Myth #3: Root Canals Cause Illness

This myth originated from century-old, debunked research. Multiple large-scale scientific studies have found no causal link between root canal treatment and systemic disease. In reality, leaving an infected tooth untreated poses far greater health risks: oral bacteria can enter the bloodstream and contribute to heart disease and other complications.

What Actually Happens During a Root Canal

Your dentist begins by numbing the area with a local anaesthetic. A small opening is made in the tooth to access the pulp chamber, where infected nerve tissue is carefully removed. The canals are cleaned, shaped, and disinfected, then filled with a biocompatible material. The tooth is sealed and, in most cases, topped with a crown to restore its strength and appearance. The entire process typically takes one to two appointments.

Recovery and Aftercare

Mild soreness for a few days after the procedure is normal and manageable with over-the-counter pain relievers. Avoid chewing on the treated side until your crown is placed, eat soft foods, and maintain your normal oral hygiene routine. Most patients return to their usual activities the same day. With proper care, a tooth that has had a root canal can last a lifetime.
