If any dental procedure has an undeserved bad reputation, it's the root canal. Surveys consistently show that people fear root canals more than almost any other dental treatment — yet patients who've actually had a modern root canal typically describe it as being surprisingly unremarkable. No worse, many say, than getting a filling.
The disconnect comes from two sources: outdated experiences and secondhand horror stories. At The Smile Doctors in Nepean, we perform root canal treatments regularly, and we're here to give you an accurate, honest picture of what the procedure actually involves.
What Happens Inside a Tooth That Needs a Root Canal?
Every tooth contains an inner chamber called the pulp, which houses nerves, blood vessels, and connective tissue. This pulp is essential during tooth development but is no longer necessary once the tooth is fully formed. When bacteria penetrate deep into the tooth — through severe decay, a crack, or trauma — the pulp can become infected or die.
An infected pulp is the source of that unmistakable deep, throbbing toothache that can feel relentless. A root canal resolves the infection by removing the damaged pulp, thoroughly cleaning and shaping the inner canals, and sealing the tooth to prevent reinfection. The tooth stays in place, typically restored with a crown for long-term protection.
Signs a Root Canal Might Be Needed
The clearest indicator is severe, persistent tooth pain — particularly throbbing pain that worsens at night or with heat. Prolonged sensitivity to heat or cold that lingers after the stimulus is removed, darkening of the tooth, gum tenderness and swelling, and a persistent pimple-like bump on the gum near the tooth are all signs that warrant prompt evaluation.
Sometimes infected teeth cause no pain at all — which is one reason regular dental X-rays matter. Catching infection before it progresses to abscess makes treatment simpler and outcomes better.
The Procedure at The Smile Doctors: What to Expect
We begin with thorough local anaesthesia to ensure the area is completely numb. Most patients are pleasantly surprised that they feel nothing painful during the procedure itself — just some pressure and gentle movement. For patients with significant dental anxiety, we also offer nitrous oxide sedation.
The procedure involves creating a small opening in the crown of the tooth, removing the infected or dead pulp tissue, carefully cleaning and shaping the root canals with specialized instruments, filling the canals with a biocompatible material, and sealing the tooth. The whole process typically takes 60 to 90 minutes.
Following the procedure, a crown is usually placed on the treated tooth to restore its strength and protect it from fracture. Without a crown, root-canal-treated teeth are more prone to breaking under chewing forces over time.
Life After a Root Canal
Recovery is typically straightforward. Some mild soreness for a day or two is normal and managed with over-the-counter pain medication. The relief from the pre-procedure infection pain is often dramatic and immediate.
A properly performed root canal with a well-fitted crown can allow a tooth to function for decades. Root canal treatment, despite its reputation, is one of the most tooth-preserving procedures in modern dentistry — and preserving natural teeth is almost always the best long-term outcome.
