Pulpotomy vs Root Canal: They're Not the Same Thing

If a dentist has mentioned a "pulpotomy" for your child, or a "root canal" for yourself, it's easy to assume they're the same procedure on a smaller or larger scale. They aren't. They treat different parts of the tooth, they're usually done on different teeth, and one is not simply a junior version of the other. At Berala Dental, families travel to us from across Sydney, including the Inner West and Western Sydney, and this is one of the questions we hear most often. Here's the honest, plain-English breakdown.

First, what's inside a tooth?

Every tooth has a soft tissue centre called the pulp, which holds the nerves and blood vessels. The pulp sits in two areas:

• The coronal pulp — the part inside the crown (the visible top) of the tooth, in what's called the pulp chamber.
• The radicular pulp — the part that runs down into the roots, through the narrow root canal system to the tip of each root.

The difference between a pulpotomy and a root canal comes down to how much of that pulp is treated.

What a pulpotomy actually does

A pulpotomy removes only the coronal pulp — the portion inside the crown of the tooth. The healthy pulp in the roots is left in place. After the affected coronal tissue is removed, the chamber is treated and sealed, and the tooth is usually restored, often with a crown.

A pulpotomy is most commonly done on baby (primary) teeth, where decay has reached the pulp chamber but the root pulp is still healthy. Because baby teeth eventually fall out on their own, the goal is to keep the tooth comfortable and functional until it's naturally lost — which helps protect the spacing for the adult teeth coming through underneath.

This is the part people get wrong most often, so we'll be blunt about it: a pulpotomy is not a "mini root canal". It's a genuinely different procedure that treats a different part of the tooth. Calling it a mini root canal misrepresents what's happening, and we think families deserve the accurate picture.

What a root canal actually does

A root canal treats the full canal system. The inflamed or infected pulp is removed from both the crown and the roots, then the inside of the tooth is cleaned, shaped and disinfected along the whole length of each canal, right down toward the root tip. The cleaned canals are filled and sealed, and the tooth is then restored, often with a crown for protection.

Root canal treatment is usually done on adult (permanent) teeth — the ones you keep for life — where the aim is to save the natural tooth rather than remove it. According to the American Association of Endodontists, the procedure is designed to eliminate bacteria from the infected canal, prevent reinfection, and keep the natural tooth in place.

The key differences at a glance

• How much pulp is removed: a pulpotomy removes the coronal pulp only; a root canal removes pulp from the entire canal system, including the roots.
• Which teeth: a pulpotomy is most often done on baby teeth; a root canal is most often done on adult teeth.
• The goal: a pulpotomy aims to keep a baby tooth comfortable and functional until it falls out naturally; a root canal aims to save an adult tooth for the long term.
• Not a smaller version: they are separate procedures, not two sizes of the same one.

Why the distinction matters for your family

Knowing the difference helps you ask the right questions and understand exactly what's being recommended and why. A pulpotomy on a child's baby tooth and a root canal on an adult tooth are different decisions with different goals — so it's worth being clear which one a dentist is actually talking about.

If your child needs pulp treatment on a baby tooth and they have a Medicare card and your family receives an eligible payment such as Family Tax Benefit Part A at least once that year, the Child Dental Benefits Schedule (CDBS) may help with the cost. The CDBS covers eligible children aged 0–17 for things like exams, X-rays, cleans, fillings, extractions and pulp treatment on baby teeth, capped at $1,158 per child over a two-year period for periods starting in 2026. CDBS treatment is bulk-billed, meaning no out-of-pocket cost to you for covered items — Medicare pays the clinic directly. You can check eligibility through our CDBS checker. Note that CDBS does not cover items like orthodontics, cosmetic work or treatment under general anaesthetic.

Every situation is different, and only an in-person assessment can tell you which procedure (if any) a tooth actually needs. This article explains the general difference — it isn't a diagnosis or treatment advice.

Not sure which one your tooth needs?

The clearest way to find out is to have the tooth assessed properly. Book online with Berala Dental and our team will examine the tooth, explain your options in plain language, and walk you through what's involved before anything is decided.
