Root Canal Treatment: What Actually Happens, Step by Step

Ask anyone to name the most feared dental procedure and you will hear "root canal". That reputation was earned decades ago, with old instruments and weaker anaesthesia. Modern rotary endodontics is a different procedure entirely.

Why a root canal is needed

Inside every tooth is a soft pulp containing nerves and blood vessels. When decay or a crack reaches it, the pulp becomes infected. The infection cannot heal on its own — it spreads towards the bone.

Step 1 — Numbing

We use a topical gel first, then a computer-controlled anaesthetic delivery that releases the fluid slowly. Most patients report feeling only the gel.

Step 2 — Isolation

A rubber dam isolates the tooth. It keeps the field sterile and means nothing touches your throat.

Step 3 — Cleaning and shaping

Rotary nickel-titanium files clean the canal in minutes rather than the long manual filing of older methods. An apex locator tells us the exact canal length electronically.

Step 4 — Sealing

The canal is filled with a biocompatible material and sealed so bacteria cannot re-enter.

Step 5 — The crown

A treated tooth becomes brittle. A crown restores full chewing strength, and we design it digitally to match your other teeth.

How long does it take?

In most cases, one appointment of 45 to 90 minutes. Complex or heavily infected cases may need two.

Pain afterwards is usually mild and settles within two days with standard painkillers.
