A parent hears "your child needs a root canal" and the stomach drops. Take a breath. On baby teeth, what's usually being recommended is a pulpotomy — a smaller, shorter, far less dramatic procedure than the root canal adults picture. The two get mixed up constantly, including by dentists explaining things in a hurry.
Here's the difference in plain English, and how we decide which — if either — a tooth actually needs.
If your child has been complaining about a tooth, having it looked at early keeps the most options open.

Pulpotomy vs root canal: one removes part, one removes all
Every tooth has a soft living core called the pulp — nerves and blood vessels. When decay reaches it, the pulp becomes inflamed and infected. The question is always how far the trouble has spread.
A pulpotomy removes only the infected top portion
In a pulpotomy, we remove the inflamed pulp from the crown of the tooth — the part above the gum — and leave the healthy pulp in the roots alive. A soothing medicated dressing goes over it, and the tooth is sealed, usually with a crown strong enough to survive years of chewing. It's the standard nerve treatment for baby molars. One visit, local anaesthetic, done.
A root canal removes all of it
A full root canal treatment removes the pulp from the crown and the roots, then cleans, shapes and fills the entire canal system. It's the right treatment for adult teeth, and occasionally for baby teeth in specific situations — but for most primary molars, it's more procedure than the tooth needs.
Why save a baby tooth at all?
Fair question — it's falling out anyway. But baby molars can be needed until age ten or twelve, and losing one early causes real problems:
- Space loss. Neighbouring teeth drift into the gap, and the adult tooth underneath can come through crooked or blocked.
- Chewing and nutrition suffer on that side of the mouth.
- Speech can be affected while sounds are still developing.
- Pain and infection risk — a decayed tooth left alone doesn't stay quiet.
Not sure whether a tooth can still be saved? An examination and an X-ray are what answer that.

How we actually decide — pain patterns tell the story
The type of pain matters more than parents expect. A tooth that hurts only when eating, then settles, often still has pulp we can save — that's pulpotomy territory. A tooth that wakes your child at night, aches on its own, or comes with a gum pimple or facial swelling has usually gone past saving the nerve, and the honest conversation becomes extraction and space management instead.
X-rays settle the rest. Sometimes the kindest treatment is the simplest one. We'd rather tell you that plainly than recommend a procedure the tooth can't benefit from — our whole approach to children's dentistry is built around that honesty.
Quick answers
Is a pulpotomy the same as a root canal?
No. A pulpotomy removes only the infected pulp in the crown of the tooth and keeps the root pulp alive — it's the usual nerve treatment for baby teeth. A root canal removes and fills all of the pulp, roots included, and is mainly for adult teeth.
Does a pulpotomy hurt?
The tooth is fully numbed with local anaesthetic first, and most children cope better than their parents expect. We pace the visit around the child — gentle introductions, breaks when needed, no surprises.
What happens if we just pull the tooth instead?
Sometimes that is the right call. But an early gap usually needs a space maintainer so the surrounding teeth don't drift and block the adult tooth coming through. We'll always explain both paths and what each means down the track.
If your child has a toothache that isn't settling, don't wait for it to become a night-time emergency — Berala Dental has cared for Sydney families since 2002 and sees children every day.
