A pulpotomy, often called a baby root canal, removes the infected or inflamed pulp from the top chamber of a decayed or injured baby tooth while leaving the healthy roots in place. It relieves pain and saves the tooth so it can hold its space until the permanent tooth is ready. Call (760) 744-8600.
If your child has a deep cavity or a toothache, you may hear the words baby root canal, and they can sound scarier than the procedure actually is. At San Marcos Kids Dentistry, a pulpotomy is a routine, gentle way to save a baby tooth that has decay or injury reaching the nerve. Led by board-certified pediatric dentist Dr. Nikki Shafiei, our team keeps the visit calm and comfortable, treats only what needs treating, and protects the tooth so it can do its job until it is ready to fall out naturally. This page walks through what a pulpotomy is, when a child needs one, and exactly what to expect.
What Is a Pulpotomy?
A pulpotomy treats infection or inflammation that is confined to the pulp chamber, the soft inner part at the top of the tooth that holds the nerve. We gently remove the affected pulp from that chamber, place a medicated material to soothe and protect what remains, and then cover the tooth with a crown so it stays strong. Unlike treatment on a permanent tooth, the healthy root tissue is left in place. Most pulpotomies take about as long as a filling, and children are awake and comfortable, often with a little sedation or comfort support if they feel anxious.
Pulpotomy vs. Pulpectomy: What Is the Difference?
Parents often see both words, so here is the simple version. A pulpotomy removes pulp from only the upper chamber, when the infection has not reached the roots. A pulpectomy goes further, removing pulp from the chamber and the root canals, and is used when infection has spread deeper. We choose the right approach after looking at the tooth and an X-ray. Both aim for the same goal: relieve discomfort and keep the natural tooth in place when possible. For broader nerve concerns, see our nerve and pulp treatment page.
Why Save a Baby Tooth at All?
It is a fair question, since baby teeth fall out anyway. But they do important work first. A healthy baby tooth helps your child chew and eat well, speak clearly, and feel confident, and it holds the right amount of space for the permanent tooth forming underneath. If a baby tooth is lost too early to infection, neighboring teeth can drift into the gap, which can crowd the permanent tooth and lead to the need for space maintainers or orthodontics later. Saving the tooth now often means a simpler path ahead.
Signs Your Child May Need a Baby Root Canal
A pulpotomy may be recommended when decay or injury reaches the nerve. Watch for:
- A toothache or lingering pain, especially at night
- Sensitivity to hot or cold that does not go away
- A deep or large cavity
- Swelling or a small pimple-like bump on the gum near a tooth
- A tooth that was chipped or knocked in a fall
If you notice any of these, schedule a visit. Early evaluation often means a smaller, simpler treatment.
What to Expect During the Procedure
We start by making sure your child is comfortable and the area is fully numb. Then we remove the decay and the affected pulp from the chamber, place a soothing medicated dressing, and restore the tooth with a crown, often a durable stainless steel or a tooth-colored zirconia crown, so it can withstand normal chewing. The whole visit is usually quick. Afterward, your child can return to normal activities, and we will share simple aftercare tips for the day or two that follow.
Is a Pulpotomy Safe and Does It Work?
Yes. Pulpotomies are a well-established, routine pediatric procedure with high success rates, and they are far gentler than many parents expect. The tooth stays in place, your child keeps chewing and smiling normally, and the space for the permanent tooth is protected. We will always talk through the options with you, including when saving the tooth is the best choice and when another approach makes more sense.
Frequently Asked Questions
Q: Does a baby root canal hurt?
A: The tooth is fully numbed first, so the procedure itself is comfortable. Many children are surprised by how easy it is. We offer comfort and sedation options for anxious kids.
Q: At what age can a child have a pulpotomy?
A: A pulpotomy can be done on a primary tooth at almost any age, commonly between the toddler years and about age 12, whenever a baby tooth with deep decay or injury can be saved.
Q: Will my child need a crown after the pulpotomy?
A: Usually yes. A crown protects the treated tooth so it stays strong for chewing until it is naturally replaced. We use kid-sized stainless steel or tooth-colored zirconia crowns.
Q: Is a baby root canal covered by insurance?
A: Many dental plans cover pulpotomies and crowns on baby teeth. Our team verifies your benefits and gives you a clear estimate before treatment begins.
