When decay reaches the pulp inside a baby tooth, it can cause pain and infection. A baby root canal (pulpotomy) removes the affected tissue to treat the problem, relieve discomfort, and help prevent the infection from spreading. When the tooth can be saved, treatment also allows it to remain in place until it naturally falls out.

Why Save a Baby Tooth If It Will Eventually Fall Out?
You may wonder why your child needs a pulpotomy when the baby tooth will eventually fall out anyway. While removing the tooth may seem like a simpler option, some baby teeth need to remain in place for several more years. Losing them too early can affect how your child’s permanent teeth develop.
A pulpotomy may be recommended because it can:
- Preserve space for permanent teeth. Baby teeth hold space for the adult teeth developing underneath. If a tooth is removed too early, neighboring teeth may shift into the empty space, causing crowding or alignment problems.
- Avoid additional dental treatment. If a baby tooth is extracted prematurely, your child may need a space maintainer to prevent nearby teeth from shifting. This means additional appointments and treatment costs.
- Treat damaged pulp tissue. A pulpotomy removes inflamed or damaged pulp from the upper portion of the tooth while preserving healthy tissue in the roots.
- Maintain normal chewing and speech. Keeping the natural tooth allows your child to continue eating comfortably and supports proper speech development.
When Might a Baby Root Canal Be Needed?
At Stanley Pediatric Dentistry, Dr. Kate may recommend a pulpotomy, commonly called a baby root canal, when a deep cavity or injury has damaged the pulp inside a baby tooth, but the tissue in the roots is still healthy.
We may recommend a pulpotomy when:
- Deep tooth decay reaches the pulp. Bacteria from a large cavity can reach the soft tissue inside the tooth, causing inflammation.
- An injury exposes the pulp. A broken or fractured tooth may expose the inner tissue, even if the tooth was previously healthy.
- The tooth can still be restored. Enough healthy tooth structure must remain to support a filling or dental crown after treatment.
- The root tissue is healthy. A pulpotomy may be appropriate when inflammation is limited to the pulp in the crown of the tooth, without signs of irreversible damage or infection in the roots.
During your child’s dental exam, Dr. Kate will evaluate the tooth and review dental X-rays when needed to determine whether a pulpotomy is the best treatment or if another approach would be more appropriate.
Is Saving the Baby Tooth Always the Best Option?
In some cases, removing a baby tooth may be better than trying to save it. The decision depends on the condition of the tooth and roots, how much healthy tooth remains, and how soon the tooth is expected to fall out naturally.
Dr. Kate takes an individualized approach to treatment, considering your child’s age, dental development, comfort level, and ability to tolerate treatment. We also understand that families have different needs and financial considerations. Our goal is to recommend treatment that is appropriate for your child’s oral health while taking your family’s circumstances and budget into account.
FAQs
What is a pulpotomy?
A pulpotomy is a treatment commonly referred to as a baby root canal. It removes damaged or inflamed pulp from the upper part of the tooth while preserving healthy root tissue. The tooth is then restored to keep it protected and functional.
Does a root canal on baby teeth affect permanent teeth?
A properly performed pulpotomy should not affect the permanent tooth developing underneath. The treatment is limited to the baby tooth and helps keep it healthy until it naturally falls out. However, untreated decay or infection in a baby tooth can potentially damage the developing permanent tooth.
Will my child need a crown after a baby root canal?
In most cases, yes. A dental crown is often recommended after a pulpotomy, especially on a back baby tooth. The crown protects the remaining tooth structure and helps prevent it from breaking during normal biting and chewing.
