If your pediatric dentist has recommended a pulpotomy, you probably have questions. The first is usually simple: what is a pulpotomy for kids, and why can’t the dentist just put in a filling? A pulpotomy is often called a “baby root canal.” It is a common, gentle procedure that saves a baby tooth when decay has reached the nerve.
What Happens Inside the Tooth
Every tooth has a soft center called the pulp, which contains nerves and blood vessels. When a cavity grows deep enough to reach the pulp, bacteria can inflame it and cause pain, sensitivity, or infection. A regular filling cannot fix that, because the problem is inside the tooth, not just on the surface.
During a pulpotomy, we remove only the inflamed pulp in the crown of the tooth, the part above the gumline, and leave the healthy pulp in the roots. We then place a soothing medicine to protect the remaining pulp and seal the tooth.
How It Differs From an Adult Root Canal
An adult root canal removes all of the pulp, including the nerves inside every root. A pulpotomy removes only the top portion. That makes it faster, simpler, and much better suited to baby teeth, which only need to last until the adult tooth is ready to come in. You can read more on our root canal for kids page.
Signs Your Child May Need a Pulpotomy
- Toothache that keeps coming back, especially at night
- Sensitivity to hot or cold that lingers
- A large cavity that is visible or found on an x-ray
- A cracked tooth with a deep break
- Pain when chewing on one side
What the Visit Looks Like
- The tooth is completely numbed with local anesthetic
- Decay and the inflamed pulp in the crown are gently removed
- A medicated material is placed to protect the healthy root pulp
- The tooth is restored, most often with a crown, so it can handle chewing forces
Most appointments take under an hour. Children who are nervous can often have laughing gas or other comfort options.
Why Save a Baby Tooth at All?
It is tempting to think a baby tooth is not worth saving because it will fall out anyway. But baby back teeth often stay until ages ten to twelve. They help your child chew, speak clearly, and, most importantly, hold space for the adult teeth. Losing one early can let nearby teeth drift and cause crowding later. The American Academy of Pediatric Dentistry supports saving healthy baby teeth whenever it is possible.
How Long Does a Pulpotomy Last?
A pulpotomy with a well-fitted crown usually lasts until the baby tooth falls out naturally. We check it at every six-month visit, along with the rest of your child’s teeth.
Recovery at Home
Your child may feel a little sore for a day or two. Soft foods and children’s pain reliever, given according to the package directions, usually help. Watch for lip or cheek chewing while the numbness wears off.
The Bottom Line: What Is a Pulpotomy for Kids?
So, what is a pulpotomy for kids? It is a quick, reliable way to remove an infected nerve, stop the pain, and keep a baby tooth in place until it is ready to go. If your child has a toothache that will not go away, do not wait. Early care keeps treatment simpler.
