When we hear the term “root canal,” many of us immediately think of a complex dental procedure often associated with pain and discomfort. However, when it comes to pediatric dentistry, the term takes on a slightly different meaning. A “baby root canal” or “pulpotomy” is a common dental procedure performed on children’s primary (baby) teeth. In this article, we’ll delve into what a baby root canal is, why it’s necessary, and what parents can expect during the process.

What is a Baby Root Canal?

When it comes to pediatric dentistry, the term “baby root canal” can refer to two distinct procedures: pulpotomy and pulpectomy. Both are designed to treat infected pulp tissue in a child’s primary (baby) tooth, but they differ in their approach and the extent of the treatment. Let’s delve into the definitions, explanations, and recommendations for each procedure.

1. Pulpotomy

Definition: A pulpotomy is a procedure where the infected or damaged pulp tissue from the crown (the visible part) of a baby tooth is removed. Unlike a traditional root canal performed on permanent teeth, a pulpotomy only removes the pulp from the crown (the visible part) of the tooth, leaving the pulp in the roots intact.

Explanation: During a pulpotomy, the dentist will remove the decayed portions of the tooth to access the pulp chamber. Once accessed, the infected or inflamed pulp tissue in the crown is removed. After the removal, a medicated filling is placed in the tooth to prevent further infection and maintain the vitality of the remaining pulp tissue. The tooth is then sealed, often with a dental crown, to protect and strengthen it.

When is it recommended?

  • When the infection or decay is limited to the pulp of the crown.
  • When there’s a need to preserve the vitality of the remaining pulp tissue in the roots, which can continue to nourish the tooth.
  • For teeth that have a good prognosis for survival until they naturally fall out.

2. Pulpectomy

Definition: A pulpectomy involves the removal of the entire pulp tissue from both the crown and the roots of a baby tooth.

Explanation: In this procedure, after accessing the pulp chamber, the dentist removes the pulp tissue from both the crown and the root canals. The root canals are then cleaned, shaped, and disinfected to eliminate any remaining bacteria. Once cleaned, the canals and pulp chamber are filled with a resorbable material, and the tooth is sealed, typically with a dental crown.

When is it recommended?

  • When the infection or decay has spread to the pulp of both the crown and the roots.
  • When there’s a risk of the infection spreading further or affecting the developing permanent tooth beneath.
  • For teeth where a pulpotomy is deemed insufficient due to the extent of the infection.

It is important to note that a pulpotomy is a more common approach to treating baby teeth as compared to the pulpectomy. However, only your pediatric dentist can recommend which baby root canal approach is best for your child. 

Why is it Necessary?

You might wonder, “If baby teeth are temporary and will eventually fall out, why go through the procedure?” Here are some reasons:

  1. Pain Relief: An infected or decayed baby tooth can cause significant pain and discomfort for a child. A baby root canal can alleviate this pain by treating the source of the infection.
  2. Prevent Spread of Infection: If the infection within a baby tooth is left untreated, it can spread to neighboring teeth or even to other parts of the body, leading to more severe health complications.
  3. Preservation of Baby Teeth: While baby teeth are temporary and will eventually fall out, they play several crucial roles:
  4. Space Maintenance: Baby teeth hold space in the jaw for the permanent teeth that are growing under the gums. If a baby tooth is lost too early, neighboring teeth might drift into the empty space, potentially leading to crowding or misalignment of permanent teeth.
  5. Chewing and Nutrition: Baby teeth are essential for chewing, which ensures proper nutrition.
  6. Speech Development: Teeth play a role in speech development, helping children pronounce words correctly.
  7. Normal Development of Jaw Bones and Muscles: The presence of baby teeth aids in the proper growth and development of the jaw bones and muscles.
  8. Avoid Dental Abscess: If the infection reaches the pulp of the tooth and is not treated, it can lead to a dental abscess, a pocket of pus that forms due to a bacterial infection. This condition can be painful and might require more extensive treatment.
  9. Protect the Developing Permanent Tooth: An untreated infection in a primary tooth can potentially damage the developing permanent tooth underneath.
  10. Maintain Oral Health: Treating infected or decayed baby teeth promotes overall oral health, reducing the risk of spreading bacteria to other areas of the mouth.

What to Expect During the Procedure

When a child is scheduled to have a baby root canal, it’s natural for parents to feel anxious or have concerns. Understanding the procedure and knowing what to expect can help alleviate some of these worries. Here’s a step-by-step guide for parents on what to anticipate:

  1. Discussion with the Dentist: The pediatric dentist will explain the need for the procedure, its benefits, and potential risks. Parents should feel free to ask any questions or voice concerns.
  2. X-rays: The dentist might take X-rays of the affected tooth to assess the extent of the infection and plan the procedure.
  3. Anesthesia: The dentist will administer local anesthesia to numb the area around the affected tooth. This ensures the child feels no pain during the procedure. In some cases, dental sedation or general anesthesia may be recommended, especially for very young children or those who are particularly anxious.
  4. Tooth Isolation: A rubber dam might be placed around the tooth to keep it dry and free from saliva during the procedure.
  5. Decay Removal: The dentist will remove any decayed portions of the tooth to access the pulp chamber.
  6. Pulp Treatment: Depending on the type of baby root canal (pulpotomy or pulpectomy), the dentist will either remove the infected pulp from the crown or from both the crown and roots.
  7. Filling and Sealing: After treating the pulp, the dentist will place a medicated filling in the tooth. The tooth is then sealed, often with a dental crown, to protect and strengthen it.

After the procedure, it’s normal for the child to experience some sensitivity or discomfort, which usually subsides in a few days. Over-the-counter pain relievers can help manage any post-procedure pain. It’s essential to follow the dentist’s aftercare instructions, including maintaining good oral hygiene and avoiding hard or sticky foods for a few days.

Preventing the Need for a Baby Root Canal

Preventing the need for a baby root canal largely revolves around maintaining good oral hygiene and adopting healthy dental habits from an early age. Here are some steps parents can take to reduce the risk of their child needing a baby root canal:

Start Early:

  • Begin Dental Care Early: Even before the first tooth emerges, parents can gently clean their baby’s gums with a soft, damp washcloth.
  • First Dental Visit: Schedule the child’s first dental visit by their first birthday or when the first tooth appears, whichever comes first.

Adopt Good Oral Hygiene Habits:

  • Brushing: As soon as teeth appear, start brushing them twice a day using a soft-bristled toothbrush and a tiny smear of fluoride toothpaste (about the size of a grain of rice). By age 3, a pea-sized amount of toothpaste can be used.
  • Flossing: Begin flossing once two teeth touch each other.
  • Regular Dental Check-ups: Ensure your child visits the dentist regularly, typically every six months, for professional cleanings and check-ups.

Healthy Diet:

  • Limit Sugary Foods and Drinks: Sugars feed the bacteria that produce acid, which can erode tooth enamel and lead to cavities.
  • Avoid Frequent Snacking: Constant snacking can provide a continuous food source for bacteria, increasing the risk of cavities.
  • Promote Water: Encourage drinking water, especially if it’s fluoridated, over sugary drinks like sodas and juices.
  • Healthy Snacks: Offer snacks like fruits, vegetables, and cheese, which are better for teeth than sugary or starchy snacks.

Preventative Treatments:

  • Fluoride: Ensure your child gets enough fluoride, which strengthens tooth enamel and reduces the risk of decay. This can come from fluoridated water, toothpaste, or professional fluoride treatments.
  • Dental Sealants: Consider dental sealants for your child. Sealants are a protective coating applied to the chewing surfaces of the back teeth, preventing food and bacteria from getting trapped in the grooves and causing decay.

Avoid Bottle Decay:

  • Don’t Put Baby to Bed with a Bottle: Milk, formula, and juice all contain sugars that can lead to tooth decay if they remain in contact with teeth for extended periods.
  • Switch to a Cup: Transition your child from a bottle to a sippy cup by their first birthday.

Protect Against Injuries:

  • Use Mouthguards: If your child participates in sports, ensure they wear a mouthguard to protect their teeth from injury.
  • Childproof Your Home: For toddlers, ensure sharp corners and hard surfaces are padded to prevent dental injuries from falls.


  • Teach About Dental Health: As your child grows, teach them about the importance of dental health and establish it as a priority.

While these measures significantly reduce the risk of dental issues, they don’t eliminate it entirely. Regular dental check-ups are crucial as they allow for early detection and treatment of potential problems, minimizing the need for more invasive procedures like root canals.

In Conclusion

A baby root canal or pulpotomy is a safe and effective way to address infections in primary teeth. While the idea of any dental procedure on your child might be daunting, understanding the process and its benefits can provide peace of mind. Always consult with a pediatric dentist if you suspect your child might need a pulpotomy, and ensure they receive regular dental check-ups to prevent potential issues in the first place.
