Pulpectomy in Milk Teeth: Saving Infected Baby Teeth

Learn what a pulpectomy involves, when it is recommended for a child's decayed or infected baby tooth, and why preserving the tooth matters for oral development.

What Is a Pulpectomy

A pulpectomy is a procedure similar to a root canal treatment but performed on a primary, or milk, tooth. It involves removing infected or inflamed pulp tissue from both the crown and root canals of the tooth, cleaning the canal spaces, and filling them with a resorbable material suited to primary teeth, which will dissolve naturally as the tooth eventually falls out.

This treatment is recommended when decay has progressed deep enough to reach and infect the pulp, the soft tissue containing nerves and blood vessels at the centre of the tooth, causing pain, swelling, or the risk of abscess formation if left untreated.

Why Saving the Baby Tooth Matters

It may seem simpler to extract a badly decayed baby tooth rather than treat it, but premature loss of a primary tooth, especially a molar, can have lasting consequences. It may cause neighbouring teeth to drift into the empty space, reducing room for the permanent tooth that is meant to erupt there later, which can lead to crowding and the need for orthodontic correction.

Retaining the tooth also maintains normal chewing function, supports clear speech development, and prevents the psychological impact of visible gaps, particularly in the front teeth, on a young child's confidence and social interactions.

How the Procedure Is Performed

The procedure is carried out under local anaesthesia to ensure the child is comfortable and pain-free throughout. The dentist removes the infected pulp tissue, disinfects the canal system, and fills it with a material specifically formulated for primary teeth. The tooth is then typically restored with a stainless steel crown, which offers durability for the remaining years the tooth is expected to function.

Paediatric dental specialists use techniques and behaviour management approaches suited to children, often completing the procedure in a single visit to minimise the number of appointments and reduce anxiety for both the child and parent.

Aftercare and Follow-Up

Mild discomfort for a day or two following the procedure is normal and can usually be managed with paediatric-appropriate pain relief as advised by the dentist. Parents should encourage gentle brushing around the treated tooth and monitor for any signs of persistent swelling or pain, which should be reported promptly.

Regular follow-up visits allow the dentist to confirm the tooth is healing well and to monitor the natural process of root resorption as the permanent tooth develops beneath it, ensuring the treated tooth continues to function until it is naturally shed.

Questions patients ask us

Is a pulpectomy painful for a child?
The procedure itself is performed under local anaesthesia, so the child should not feel pain during treatment. Some mild soreness afterwards is normal and typically resolves within a couple of days with appropriate care and, if needed, mild pain relief suitable for children.
What is the difference between a pulpotomy and a pulpectomy?
A pulpotomy removes only the infected pulp in the crown portion of the tooth, leaving healthy pulp in the roots, and is used for less extensive infections. A pulpectomy removes pulp tissue from both the crown and the root canals and is required when infection has spread further into the tooth.
Will the treated baby tooth still fall out naturally?
Yes. The materials used to fill the canals in a pulpectomy are specifically designed to resorb, or dissolve, at the same rate as the natural tooth roots, allowing the tooth to be shed normally when it is time for the permanent tooth to erupt.
What happens if the infected tooth is simply extracted instead?
Extraction removes the source of infection but can lead to space loss, drifting of adjacent teeth, and potential crowding of permanent teeth. If extraction is unavoidable, your dentist may recommend a space maintainer to preserve the gap until the permanent tooth is ready to erupt.
