If your child’s dentist has mentioned a pulpotomy, you might picture something scary — but it’s actually one of the most common, well-established procedures in children’s dentistry. Sometimes nicknamed a “baby root canal,” a pulpotomy is a gentle way to treat a tooth when decay or an injury has reached deeper than a filling can manage, so your child can keep using that tooth comfortably until it’s naturally ready to fall out. This guide explains what a pulpotomy actually involves, in plain terms, and what to expect.
What is a pulpotomy?
Inside every tooth, under the hard outer layers, is a soft centre called the pulp. It contains small nerves and blood vessels. When decay or trauma reaches the pulp, the tooth can become sore, sensitive or infected.
A pulpotomy removes the affected part of that inner tissue from a baby tooth and treats the space to help calm irritation or infection and protect the healthy tissue that remains further down the tooth. The aim is to relieve discomfort and keep the tooth doing its job — rather than removing the tooth altogether.
It’s a common, routine part of children’s restorative dentistry, and Clinicians consulting at Tooth Town perform it regularly.
Is it the same as an adult root canal?
Not quite — the nickname is helpful, but the procedures aren’t identical. An adult root canal usually treats the whole length of the root canal system in a permanent tooth. A pulpotomy in a baby tooth is generally a more limited procedure, focused on the affected portion of the pulp, reflecting the different structure and role of baby teeth compared with permanent teeth. Your child’s clinician will explain what’s involved for their specific tooth after an examination.
Why treat the tooth instead of just taking it out?
It’s a fair question, and the answer comes down to what baby teeth do for your child in the meantime. Baby teeth help with eating and speech, guide the growth of the jaw, and hold space for the adult tooth developing underneath. Removing a tooth too early can allow neighbouring teeth to drift into that space, which may cause crowding issues later.
Where a tooth can be reasonably saved, a pulpotomy is often preferred because it:
- relieves pain and treats infection at the source
- keeps the tooth functioning for eating and speech
- holds space for the adult tooth coming through
- helps your child avoid the impact of an early gap
Extraction is sometimes the right call, depending on how much of the tooth is affected and its overall condition — that decision is always made after your child’s clinician has examined the tooth, not before.
What generally happens during a pulpotomy?
Every child and tooth is a little different, but a pulpotomy generally follows a similar pattern:
- Numbing. The area around the tooth is numbed so your child is comfortable throughout treatment.
- Treating the tooth. The clinician removes the affected inner tissue and treats the remaining healthy portion to help settle any inflammation or infection.
- Protecting the tooth. The tooth is then usually restored with a crown, which protects it and helps it cope with everyday biting and chewing. We have a separate guide that explains the different types of children’s crowns Tooth Town uses and how we choose between them.
Afterwards, the tooth is generally monitored at regular check-ups to make sure it’s settling well and continuing to do its job.
Will my child be comfortable during treatment?
We know it’s natural to worry about how your child will cope. Pulpotomies are usually completed comfortably with local numbing, and our team takes a calm, child-friendly approach to help your child feel at ease throughout — explaining things in simple language, going at their pace and using positive, reassuring techniques.
For children who feel more anxious, have additional needs, or need extra support to get through treatment comfortably, options such as happy gas (relative analgesia) or, in some cases, treatment under general anaesthesia may be suitable. What’s right for your child depends on their individual needs and will be discussed with you by their clinician — we won’t assume a particular option in advance.
What happens after the procedure?
Your child’s clinician will let you know what to expect once treatment is complete, including any care instructions for the days that follow and when to bring your child back for review. As with any dental treatment, a pulpotomy is generally successful in appropriate cases, but the tooth will continue to be monitored at future visits to check it’s settling as expected. If you notice ongoing pain, swelling or anything you’re unsure about after the appointment, please contact our team.
Frequently asked questions
What is a pulpotomy?
A pulpotomy is a treatment for a baby tooth where decay or trauma has reached the tooth’s inner pulp. It removes the affected tissue and treats the tooth to relieve discomfort and help save it, usually followed by a protective crown.
Is a pulpotomy painful for my child?
The tooth is numbed before treatment, and our team takes a gentle, child-friendly approach throughout. For children who need extra support, options like happy gas or general anaesthesia can be discussed with your clinician.
Why not just take the tooth out instead?
Baby teeth help your child eat and speak, and they hold space for the adult tooth developing underneath. Where a tooth can be reasonably saved, treating it can help avoid the effects of an early gap.
Is a pulpotomy the same as an adult root canal?
Not exactly. It’s sometimes called a “baby root canal,” but a pulpotomy in a baby tooth is generally more limited than an adult root canal, reflecting the different structure of baby teeth.
Does my child need a crown after a pulpotomy?
Usually, yes — a crown helps protect the treated tooth so it can cope with everyday biting and chewing. Our separate guide explains the crown options Tooth Town offers.
How do I know if my child needs a pulpotomy?
Only an in-person examination can confirm this. If your child has tooth pain, sensitivity or you’ve noticed a change in a tooth, book a check-up and their clinician will assess what treatment, if any, is appropriate.
What to do next
If your child has been experiencing tooth discomfort, or their clinician has mentioned they may need a pulpotomy, the best next step is a check-up so we can properly assess the tooth and talk you through the options. Book an appointment with our friendly team — we’re here to answer your questions and help your child feel at ease every step of the way.
This guide is general information and doesn’t replace an individual assessment. Your child’s clinician will confirm what’s most appropriate for them after examination.
