A pulpotomy, sometimes called a “baby root canal,” is a gentle procedure that removes the infected part of the soft tissue inside a tooth while preserving the healthy portion. It relieves pain, stops infection, and saves the natural tooth. At Smile Arc Pediatric Dentistry in San Diego, we perform pulp therapy with local anesthesia and calming options to keep your child comfortable.
If you have learned that your child needs nerve or pulp treatment, it is natural to feel concerned. The reassuring news is that this is a common, well-established pediatric procedure designed to save a tooth and end your child’s discomfort. You may hear it called a pulpotomy, nerve treatment, or a “baby root canal,” and these terms all refer to the same goal: removing infection while keeping the tooth healthy and in place. At Smile Arc Pediatric Dentistry in San Diego, we walk your family through every step and keep your child calm and comfortable throughout.
What Is Tooth Pulp?
Inside every tooth is a soft center called the pulp. It contains the nerves and blood vessels that supply the tooth with nutrients and keep it alive. When deep decay or an injury reaches the pulp, it can become inflamed or infected, causing swelling and pain. In young, growing teeth, the pulp also plays a role in healthy root development, which is one more reason it is worth protecting whenever we can.
What Is a Pulpotomy (Baby Root Canal)?
A pulpotomy is the most common form of pulp therapy for children. During the procedure, we remove only the diseased portion of the pulp while preserving as much healthy tissue and root structure as possible. Once the infected part is removed, we place a medicated material that calms the tooth and prevents bacteria from growing. In most cases, we then protect the tooth with a crown, which restores its strength and guards against future fractures.
People often call this a “baby root canal,” but it is gentler and more conservative than a full adult root canal. It is tailored specifically to children’s teeth and developing roots, and it can be done on baby teeth or young permanent teeth.
Signs Your Child May Need Pulp Treatment
The pulp can become exposed or infected after deep decay or a dental injury. Warning signs to watch for include:
- Constant, throbbing, or unexplained tooth pain
- Pain that is worse at night
- Sensitivity to hot or cold that lingers
- Swelling or tenderness in the gum around a tooth
- A tooth that has darkened after an injury
If your child has any of these symptoms, please call our office. Some pulp problems cause little pain at first, which is another reason regular checkups matter, since we can often spot trouble on an exam or X-ray before it becomes an emergency.
Why Saving the Tooth Matters
It is tempting to think an infected baby tooth should just be removed, but saving it is usually the better choice when possible. Baby teeth hold space for the permanent teeth forming underneath, support proper chewing and speech, and guide adult teeth into the right position. An untreated infection can also spread to surrounding tissue and the developing permanent tooth. A pulpotomy lets your child keep a healthy, functional tooth until it is ready to fall out naturally.
What to Expect, and Keeping Your Child Comfortable
We design pulp therapy around your child’s comfort. We numb the tooth and surrounding area with local anesthetic first, so your child should feel pressure rather than pain, and for anxious children we can add nitrous oxide (laughing gas) or discuss other sedation options. The procedure is usually completed in a single visit. Afterward, mild soreness for a day or two is normal and is easily managed with the over-the-counter pain reliever we recommend. We will send you home with clear, simple aftercare instructions.
Cost & Insurance in San Diego
The cost of pulp treatment depends on the tooth involved, whether a crown is needed, and your child’s specific situation, so we provide an exact estimate after an evaluation rather than a one-size-fits-all price. Most dental insurance plans help cover pulp therapy. Our team verifies your benefits in advance, files your claims, and explains your out-of-pocket cost before treatment begins.

Frequently Asked Questions
Is a pulpotomy the same as an adult root canal?
Not quite. A pulpotomy removes only the infected upper portion of the pulp and preserves the healthy root tissue, while an adult root canal removes all of the pulp from the tooth and its roots. The pulpotomy is more conservative and is designed specifically for children’s teeth.
Why not just pull an infected baby tooth instead of doing nerve treatment?
Whenever we can, saving the natural tooth is the better choice. A baby tooth holds space for the permanent tooth underneath, supports chewing and speech, and guides the adult tooth into position. Removing it early can let neighboring teeth drift and may call for a space maintainer, so a pulpotomy that keeps the healthy tooth in place is often the more conservative option.
Will my child be in pain during or after the procedure?
We numb the area with local anesthetic, so your child should feel pressure but not pain during treatment, and gentle sedation is available if needed. Most children actually feel relief afterward because the source of infection is gone. Mild soreness for a day or two is normal and easy to manage.
Does my child need a crown after a pulpotomy?
Usually, yes. A tooth that has needed pulp therapy is more fragile, so we typically place a crown to restore its strength and protect it from fracturing. We will explain whether a crown is recommended in your child’s case.
What happens if an infected tooth nerve is not treated?
An untreated pulp infection tends to worsen, leading to more pain, swelling, and possibly an abscess. The infection can spread to nearby teeth or tissue and affect the permanent tooth developing below. Early treatment prevents these more serious problems.
Is pulp therapy safe for children?
Yes. Pulp therapy is a common and safe pediatric dental procedure when performed by a trained, board-certified pediatric dentist. We review your child’s health history, use local anesthesia, and follow clinical guidelines to make the procedure as comfortable and low-risk as possible. We are happy to answer any questions you have before we begin.
