What This Guide Covers
This guide explains pulp therapy, a set of procedures used to treat infection or damage inside a baby tooth. It is written for parents and caregivers who want to understand what happens during a pulpotomy or pulpectomy, how to prepare their child, and what recovery looks like.
Baby teeth serve a critical role beyond chewing. They hold space in the jaw so permanent teeth can grow into the correct position later. When decay reaches the inner pulp of a baby tooth, removing the tooth early can lead to crowding, misalignment, and orthodontic problems down the road. Pulp therapy offers a way to save the tooth and avoid those complications. [1]
The pulp is the soft tissue inside a tooth. It contains nerves, blood vessels, and connective tissue. In a healthy tooth, the pulp stays sealed off from bacteria. When a deep cavity or injury breaks through the outer layers of enamel and dentin, bacteria can reach the pulp and cause infection or inflammation. That is when pulp therapy becomes necessary.
If your child's dentist has recommended a pulpotomy or pulpectomy, this guide will walk you through both options, step by step.
Understanding Pulpotomy and Pulpectomy
Pulpotomy and pulpectomy are the two main types of pulp therapy for baby teeth. Which one your child needs depends on how far the infection has spread inside the tooth.
What Is a Pulpotomy?
A pulpotomy is sometimes called a "baby root canal," though it is actually less involved than a true root canal. The dentist removes only the infected pulp from the crown, which is the visible top portion of the tooth. The pulp inside the roots is left intact because it is still healthy.
After removing the diseased tissue, the dentist places a medicated material over the remaining pulp to promote healing and prevent further infection. Common medicaments include mineral trioxide aggregate (MTA), a biocompatible cement, and ferric sulfate, a chemical agent that helps control bleeding and disinfects the area. A major Cochrane systematic review, which analyzed 87 studies on pulp treatments for primary teeth with extensive decay, found that MTA may be the most effective material for pulpotomies in baby teeth, showing fewer clinical and radiographic failures than other common materials such as formocresol and calcium hydroxide. [3] A separate meta-analysis of 26 randomized controlled trials published in the Journal of Endodontics also concluded that MTA had the highest overall success rates among commonly used pulpotomy agents. [6]
A pulpotomy is typically recommended when the infection is limited to the crown pulp and the root pulp still shows signs of vitality, meaning it is alive and healthy. The procedure usually takes one visit.
What Is a Pulpectomy?
A pulpectomy is a more extensive procedure. The dentist removes all the pulp tissue from both the crown and the root canals of the baby tooth. It is closer to the full root canal treatment performed on adult teeth.
After cleaning and shaping the root canals, the dentist fills them with a resorbable paste. "Resorbable" means the filling material is designed to dissolve naturally as the baby tooth's roots break down over time, which is what happens when the permanent tooth pushes up from below. This is an important difference from adult root canals, which use a permanent filling. [1]
A pulpectomy is recommended when infection or inflammation has spread into the root pulp, but the tooth itself still has enough structure to be restored. In some cases, a pulpectomy may require two visits if the dentist needs to place medication inside the canals between appointments to manage a severe infection.
Pulpotomy vs. Pulpectomy: Key Differences
Both procedures share the same goal: saving a baby tooth that would otherwise need extraction. The main difference is how much pulp tissue is removed and how far the infection has progressed.
- Scope of treatment: A pulpotomy addresses the crown pulp only. A pulpectomy addresses the crown and root canal pulp.
- Severity of infection: A pulpotomy is for cases where root pulp is still healthy. A pulpectomy is for cases where infection has reached the roots.
- Filling material: A pulpotomy uses a medicament placed over the remaining pulp. A pulpectomy uses a resorbable paste to fill the cleaned root canals.
- Number of visits: A pulpotomy is typically completed in one visit. A pulpectomy may take one or two visits.
- Success rates: The most effective modern pulpotomy materials, such as MTA, have been shown to produce very low failure rates in large systematic reviews. [3] Individual studies and meta-analyses frequently report MTA pulpotomy success rates above 90%. [6] [7] Pulpectomy success rates vary more widely depending on the extent of infection, the tooth involved, and the filling material used. [4]
Why Saving Baby Teeth Matters
Parents sometimes wonder why a baby tooth that will eventually fall out needs treatment at all. The answer comes down to timing. Baby teeth fall out on a schedule that is closely coordinated with the eruption of permanent teeth. A back molar, for example, may not be replaced by its permanent successor until age 10 to 12.
If a baby tooth is lost too early, the neighboring teeth can drift into the empty space. This crowding can force the permanent tooth to come in crooked or become trapped beneath the gum. Saving the baby tooth through pulp therapy keeps that space open and reduces the chance your child will need orthodontic treatment later. [1]
Baby teeth also play roles in speech development and proper chewing. A child missing multiple back teeth may have difficulty eating a balanced diet or developing clear speech patterns.
What Parents Need to Know Before the Procedure
Knowing what to expect ahead of time helps reduce anxiety for both you and your child. Here are the practical details.
Signs Your Child May Need Pulp Therapy
Tooth decay in children does not always cause pain in the early stages. By the time symptoms appear, the decay may have already reached the pulp. Watch for these signs and mention them to your child's dentist. [2]
- Persistent toothache: Pain that lasts more than a few minutes, especially at night or when lying down.
- Sensitivity to hot and cold: A sharp reaction to temperature that lingers after the food or drink is gone.
- Swelling: Puffy gums near a specific tooth, or swelling in the cheek or jaw.
- Darkening of the tooth: A tooth that turns gray or dark yellow may have damaged or dying pulp.
- A small bump on the gum: This is called a fistula (a small pimple-like bump). It forms when infection drains from the root tip.
- Pain when chewing: Your child avoids biting down on one side of the mouth.
Age Recommendations and Timing
Pulp therapy can be performed on children of any age once their baby teeth are fully formed. It is most commonly done between ages 3 and 10, depending on which tooth is affected. The American Academy of Pediatric Dentistry recommends that children have their first dental visit by age 1 or within six months of the first tooth appearing. [5]
Timing matters. Treating an infected tooth early, before infection spreads to the bone or affects the developing permanent tooth below, leads to better outcomes. If your child's dentist identifies deep decay during a routine exam, they may refer your child for pulp therapy even if the child is not yet feeling pain.
How to Prepare Your Child
Children take cues from their parents. Staying calm and positive sets the tone. Here are a few practical tips.
Use simple, neutral language. Saying "the dentist will clean out the sick part of your tooth and make it better" is more helpful than detailed clinical descriptions. Avoid words like "shot," "drill," or "pain." Many pediatric dental offices use child-friendly terms, such as "sleepy juice" for local anesthesia.
Bring a comfort item like a favorite stuffed animal or blanket. If your child has been to the dentist before and had a good experience, remind them of that visit. If your child is very anxious, ask the dentist about sedation options ahead of time. Nitrous oxide (laughing gas) is commonly available and provides mild relaxation during the procedure. [1]
What to Expect During and After Pulp Therapy
Both pulpotomy and pulpectomy are routine procedures performed in the dental office, typically completed in under an hour.
During the Procedure
The dentist begins by numbing the area around the tooth with local anesthesia. Your child should not feel pain during the procedure. If sedation is being used, it will be started before the anesthesia.
For a pulpotomy, the dentist removes the decay and opens the top of the tooth to access the crown pulp. The infected pulp in the crown is removed, and a medicated material is placed over the healthy root pulp. The tooth is then sealed.
For a pulpectomy, the same initial steps are followed, but the dentist continues by cleaning the pulp from the root canals using small instruments. The canals are disinfected and filled with a resorbable paste. The tooth is then sealed.
In most cases, a stainless steel crown is placed over the treated tooth during the same visit. Stainless steel crowns are durable and protect the weakened tooth structure until the baby tooth falls out on its own schedule. For front teeth, tooth-colored crowns or strip crowns may be used for a more natural appearance. [1]
Recovery and Aftercare
Most children recover quickly. Mild soreness around the treated tooth is normal for a day or two. Over-the-counter children's pain relievers, such as ibuprofen or acetaminophen, typically manage any discomfort. Follow the dosing instructions on the label or as directed by your dentist. [2]
The numbness from local anesthesia usually lasts one to two hours after the procedure. During this time, watch your child carefully. Children sometimes bite or chew on their numb lip or cheek without realizing it, which can cause an injury.
Stick to soft foods for the rest of the day. Avoid sticky or very hard foods near the crown for the first 24 hours. Your child can return to normal eating the next day in most cases.
Your dentist will schedule a follow-up visit, usually within a few weeks, to check the tooth and take an X-ray. Additional follow-up X-rays at regular intervals help confirm that the tooth is healing properly and that the permanent tooth developing below is unaffected.
Success Rates and Possible Complications
Pulp therapy for baby teeth is a well-established procedure with a strong track record. A Cochrane systematic review analyzing 87 studies on pulp treatments for primary teeth with extensive decay found that MTA and ferric sulfate both showed favorable outcomes for pulpotomies, with MTA demonstrating fewer failures overall. However, the review noted that the overall quality of available evidence was rated as low to moderate. [3] A separate meta-analysis of 26 randomized controlled trials, published in the Journal of Endodontics, found that MTA had the highest overall clinical and radiographic success rates among commonly used pulpotomy agents, with individual studies frequently reporting success rates above 90%. [6] A 2020 systematic review published in Pediatric Dentistry similarly found MTA pulpotomy success rates exceeding 90% in most studies reviewed. [7]
Pulpectomy success rates are generally slightly lower, reflecting the fact that these teeth start with more advanced infection. Outcomes also depend on the anatomy of the baby tooth's root canals, which can be irregular and difficult to clean completely. [4]
In a small number of cases, the treated tooth may develop a new infection or fail to heal. Signs of failure include recurring pain, swelling, a new fistula on the gum, or abnormal root resorption seen on X-ray. If pulp therapy fails, the tooth may need to be extracted. A space maintainer, a small metal appliance, can be placed to hold the gap open until the permanent tooth arrives.
Pulp Therapy Costs and Insurance
Costs for pulp therapy depend on the type of procedure, the tooth involved, and whether a crown is needed afterward. Costs vary by location, provider, and case complexity.
As a general guide, a pulpotomy on a baby tooth typically ranges from $150 to $350 per tooth. A pulpectomy, because it involves more steps, may range from $200 to $450 per tooth. A stainless steel crown, if placed at the same visit, typically adds $200 to $400. These are estimates; your child's actual costs may be higher or lower.
Most dental insurance plans that cover children include benefits for pulp therapy and crowns on baby teeth. These are generally classified as medically necessary restorative procedures rather than elective treatments. Check with your insurance provider before the appointment to understand your plan's coverage, copays, and any annual maximum limits.
If you do not have dental insurance, ask the dental office about payment plans or discount programs. Some offices offer reduced fees for uninsured patients, and community health centers may provide pediatric dental care on a sliding fee scale.
When to See a Pediatric Dentist
A pediatric dentist is a dentist who has completed additional training focused on treating children, including infants, toddlers, and adolescents. This specialty training covers child behavior management, sedation, and treatment of developing teeth.
Many general dentists perform pulpotomies on baby teeth as part of their regular practice. However, there are situations where a referral to a pediatric dentist is the better choice.
- Very young children: Toddlers and preschoolers often need specialized behavior management or sedation techniques to sit through treatment safely.
- Multiple teeth needing treatment: If your child has several teeth with deep decay, a pediatric dentist can coordinate a treatment plan and may recommend treating multiple teeth under sedation in one visit.
- Children with special health care needs: Children with medical conditions, developmental disabilities, or severe dental anxiety benefit from the specialized training a pediatric dentist provides.
- Complex cases: If the infection involves the bone around the tooth root, or if the tooth anatomy is unusual, a pediatric dentist has the training and equipment to handle these situations.
- Previous treatment failure: If a pulpotomy or pulpectomy performed by a general dentist has not healed as expected, a pediatric dentist can evaluate the tooth and recommend next steps.
