Why Does My Child Need a Pulpotomy? Understanding the “Baby Root Canal”

Posted on February 16, 2026

Few phrases will stop a parent faster than “your child needs a root canal.” It makes you think of the adult procedure, and when it’s attached to a tooth that’s going to fall out anyway, it may not seem to make much sense. Why worry about all the discomfort and cost if the tooth isn’t permanent?

 

What Is a Pulpotomy?

 

A pulpotomy isn’t the same thing as an adult root canal, even though the underlying concept is related. In an adult root canal, the dentist removes all of the pulp (the soft tissue that holds the nerves and blood vessels) from the entire length of the tooth’s root canals. It’s a more involved procedure because adult teeth have long roots.

 

In a pulpotomy, the dentist removes only the pulp from the crown portion of the tooth (the part above the gum) and leaves the pulp in the roots alone. A medicated material is added where the pulp was removed, a protective cap is set over it, and the tooth is usually restored with a stainless steel crown to hold everything together.

 

The whole thing is done under local anesthesia, so your child shouldn’t feel anything. Most kids can eat normally within a few hours.

 

Why Save a Tooth That’s Going to Fall Out?

 

Why go to all the trouble of a root canal for a tooth that isn’t going to stay more than a few years? There are several reasons.

 

Each baby tooth is a placeholder for the permanent tooth developing directly beneath it in the jaw. When a baby tooth is lost prematurely, that space doesn’t stay open while the permanent tooth finishes developing. The neighboring teeth drift, which means the permanent tooth comes in crowded or rotated, or it could be blocked.

 

Baby teeth also matter for chewing, which affects nutrition, and for speech development, which is happening rapidly in early childhood. Losing a front tooth at three can affect how your child forms certain sounds, and that might mean the need for speech therapy down the road.

 

There’s also the pain and infection factor. A tooth with pulp that’s been compromised by deep decay is an active source of bacterial infection that can spread beyond the tooth. Untreated, that infection can affect the permanent tooth beneath it, spread to the surrounding bone, and in serious cases, become a systemic health issue.

 

What to Tell Your Child

 

Kids take a lot of their emotional cues from their parents when it comes to medical procedures. If you walk into the appointment anxious, they’ll pick up on it. Instead, be direct with your child. Tell them the dentist is going to fix a tooth that has a little problem inside it, you’ll get some medicine so it won’t hurt, and it’ll be done quickly.

 

The stainless steel crown that typically caps the tooth afterward is often a point of pride for younger kids. More than a few leave the office calling it their “silver tooth.”
