When your child experiences tooth pain from a deep cavity or injury, you might worry the tooth needs to be pulled. Pulp therapy offers a way to save baby teeth when decay or trauma reaches the inner pulp, preserving your child’s natural smile and avoiding the complications of early tooth loss. Depending on how much of the pulp is affected, a damaged baby tooth may be treated with a pulpotomy, a pulpectomy, or, when it cannot be saved, an extraction, and this gentle restorative treatment can often prevent the need for extraction while keeping your child comfortable throughout the process.
At Guadalupe Kids Dental, we understand how concerning it can be to hear your child needs a procedure beyond a routine filling, so we walk every family through exactly what to expect. Pulp therapy is one part of our pediatric restorative dentistry services, alongside fillings, crowns, extractions, and space maintainers.
What Is Pulp Therapy and Why Does My Child Need It?
Pulp therapy treats infected or inflamed tissue inside a baby tooth. The pulp contains nerves and blood vessels, and when bacteria from decay or cracks reach this inner chamber, your child may experience the following:
- Pain
- Swelling
- Sensitivity
Without treatment, the infection can spread and damage the developing permanent tooth below.
Baby teeth serve important functions beyond just chewing. They maintain proper spacing for permanent teeth, support jaw development, and help your child speak clearly. Losing a baby tooth too early can cause neighboring teeth to shift, potentially creating orthodontic problems down the road. Pulp therapy allows us to remove the infected pulp while keeping the tooth structure intact.
Pulpotomy, Pulpectomy, or Extraction: Three Paths for a Damaged Baby Tooth
The American Academy of Pediatric Dentistry’s pulp therapy guidance groups treatment for baby teeth by the health of the pulp. Teeth with healthy pulp or reversible inflammation are candidates for vital pulp therapy such as a pulpotomy, while teeth with irreversible inflammation or a dead pulp may need a pulpectomy. When a tooth cannot be restored, extraction becomes the safer choice.
Pulpotomy: Treating the Top of the Pulp
A pulpotomy removes only the inflamed pulp in the crown of the tooth, the part you can see above the gums, and leaves the healthy pulp in the roots in place. The remaining tissue is covered with a medicated material, and the tooth is sealed and usually protected with a crown. This is a common form of pulp therapy for baby molars with deep cavities that reach the nerve before an infection has spread to the roots.
Pulpectomy: Treating the Whole Pulp
A pulpectomy removes the pulp from both the crown and the root canals when the infection or inflammation has moved deeper. The canals are cleaned and filled with a material that the body can absorb as the baby tooth roots naturally dissolve, so the permanent tooth below can still come in on schedule. Because it treats the full length of the tooth, a pulpectomy is the procedure most parents picture when they hear the phrase “baby root canal.”
Extraction and Space Maintainers
Some teeth are too damaged to save. Extraction is usually considered when an infection cannot be controlled, too little tooth structure remains to hold a restoration, the supporting bone has been lost, or the roots have already broken down significantly. When a baby tooth is removed early, a space maintainer can hold the gap open so the permanent tooth has room to erupt. Our page on tooth extractions for kids explains what that visit involves.
| Treatment | What Is Removed | Typically Used When |
|---|---|---|
| Pulpotomy | Pulp in the crown only | Decay reaches the pulp, but the root pulp is still healthy |
| Pulpectomy | Pulp in the crown and roots | Inflammation is irreversible or the pulp has died, but the tooth can still be restored |
| Extraction | The whole tooth | The tooth cannot be restored or infection cannot be controlled |
How We Decide Between Pulp Therapy and Extraction
Some parents wonder whether extraction might be simpler than pulp therapy. While removing the tooth may seem straightforward, early tooth loss creates challenges that pulp therapy helps avoid. When a baby tooth is lost prematurely, adjacent teeth can drift into the empty space, blocking the permanent tooth from coming in properly.
Pulp therapy preserves the natural tooth until it’s ready to fall out on its own. This maintains proper spacing and alignment for the permanent tooth waiting underneath. The decision between pulp therapy and extraction depends on several factors, including:
- The extent of decay or damage
- Your child’s age and which permanent teeth are developing
- The tooth’s location and importance for spacing
- The overall health of the surrounding gum tissue
- Your child’s ability to cooperate during treatment
After examining your child and reviewing X-rays, we’ll discuss whether pulp therapy or another treatment option best suits your child’s needs. A baby tooth that is already loose and close to falling out on its own, for example, may not need pulp therapy at all.
Sedation Options for Comfortable Treatment
Every procedure starts with numbing gel and local anesthetic so the tooth is comfortable, and we offer several sedation options to help your child feel relaxed during pulp therapy.
Laughing Gas
For most procedures, nitrous oxide (laughing gas) keeps children calm and comfortable while remaining awake throughout treatment. This method helps anxious children cope with dental procedures and allows us to work efficiently. Nitrous oxide provides mild relaxation through a small mask your child breathes through during the procedure. The effects wear off quickly once the mask is removed, and most children can return to normal activities immediately.
Oral Sedation
Oral sedation uses medication taken before the appointment to create deeper relaxation, though your child remains conscious and responsive. Because the effects can linger for a few hours, a parent or guardian stays with the child for the rest of the day.

General Anesthesia at a Certified Facility
For children who are not able to tolerate treatment with nitrous oxide or oral sedation, Dr. Bennion coordinates general anesthesia appointments at a certified facility. Under general anesthesia, your child sleeps through the entire procedure, which can be helpful when several teeth need treatment, when a child is very young, or when a child’s medical or behavioral needs make lighter sedation insufficient.
We’ll help you choose the sedation level that matches your child’s temperament, the extent of treatment needed, and your family’s preferences.
What to Expect After Pulp Therapy
Following pulp therapy, your child may experience mild sensitivity for a few days. Over-the-counter pain medication usually manages any discomfort effectively. Because a treated baby tooth can become brittle, we often place a crown over it to protect it and restore full function, either a durable stainless steel crown for a back tooth or a natural-looking white crown.
Your child can typically eat soft foods once the numbness wears off and return to regular meals soon after. We’ll provide specific care instructions based on the treatment performed and the sedation method used. Regular follow-up visits let us confirm the tooth is healing well and functioning normally.
Signs a Treated Tooth Needs a Recheck
Most teeth treated with pulp therapy stay comfortable until they fall out naturally, but it helps to know what to watch for. Call our office if the tooth starts to hurt again after the first few days, if you notice swelling or a pimple-like bump on the gums near the tooth, or if the crown feels loose or comes off.
At routine checkups, we may take X-rays of the treated tooth to make sure the area around the roots stays healthy and the permanent tooth underneath is developing as expected.

Frequently Asked Questions About Pulp Therapy
Is pulp therapy the same thing as a root canal?
Not exactly. A pulpectomy, which treats the pulp in both the crown and the roots, is the closest match to a root canal and is often called a baby root canal. A pulpotomy treats only the pulp in the crown and leaves the healthy root pulp in place.
Why not just pull the infected baby tooth instead?
Early extraction can allow neighboring teeth to drift into the empty space, which can block the permanent tooth from coming in properly and create orthodontic problems later. When a tooth cannot be saved, a space maintainer can help hold that space open.
Will my child need a crown after pulp therapy?
Often, yes. A stainless steel crown or a white crown is commonly placed over the treated tooth afterward to protect it and restore full chewing function.
How long does recovery take after pulp therapy?
Most children experience only mild sensitivity for a few days, can eat soft foods once the numbness wears off, and return to a normal diet soon after.
What sedation options are available for anxious children?
Options range from nitrous oxide (laughing gas) for mild relaxation to oral sedation, and for children who need more support, general anesthesia coordinated at a certified facility, chosen based on your child’s needs and temperament.
Does pulp therapy hurt?
The tooth is numbed with a gel and local anesthetic before treatment begins, so most children feel pressure rather than pain. Mild soreness for a few days afterward is common and usually eases with over-the-counter pain medicine.
