Pulpotomy vs Pulpectomy: Which Treatment Is Right for Your Child?
A pulpotomy removes only the infected pulp in the crown of the tooth. A pulpectomy removes all the infected pulp from both the crown and the roots. Both treatments help treat an infected baby tooth and protect your child’s oral health.
When a child has a badly infected baby tooth, parents worry about pain, tooth loss, and what treatment comes next. In many cases, a pediatric dentist can save the tooth with pulp therapy. Two common treatments are pulpotomy and pulpectomy.
At Palm Valley Pediatric Dentistry & Orthodontics in Scottsdale, we provide gentle pediatric pulp therapy to treat tooth infections and, whenever possible, save baby teeth.
Key Takeaways!
Is Your Child’s Smile on the Right Track?
Early dental visits aren’t just about cleaning teeth, they’re about catching problems before they become costly and painful. Our pediatric specialists create personalized care plans that grow with your child, from their very first tooth through their teen years.
Gentle, kid-friendly care in a welcoming environment.
What Is a Pulpotomy?
A pulpotomy is a common pediatric dental treatment that removes infected pulp from the top part of a baby tooth.
Many parents call it a baby root canal, but it is different from a full root canal because it only treats part of the tooth.
Inside every tooth is a soft tissue called pulp. This pulp contains nerves and blood vessels that help the tooth grow and stay healthy. When a cavity becomes deep, bacteria can reach the pulp, causing pain, infection, and swelling.
A pulpotomy removes only the infected pulp in the crown of the tooth while keeping the healthy pulp in the roots.
This helps save the baby tooth and keeps it working until it is ready to fall out naturally.
When Does Your Child Need a Pulpotomy?
A pediatric dentist may recommend a pulpotomy when the infection has not spread into the roots. This treatment may be the right choice if your child:
- Has a deep cavity close to the tooth nerve
- Feels pain on and off but not all the time
- Shows healthy roots on dental X-rays
- Has no swelling, abscess, or serious infection
Treating the problem early can prevent the infection from worsening and save the tooth.
How Does a Pulpotomy Procedure Work?
The dentist begins by giving local anesthesia to numb the tooth and keep your child comfortable.
Next, the dentist removes the tooth decay and opens the top of the tooth to reach the infected pulp.
They clean out the damaged pulp from the crown and place a special medicated material to protect the healthy tissue inside the roots.
After that, the dentist seals the tooth and usually places a dental crown, often a stainless steel crown, to strengthen it and protect it from future damage.
The procedure is simple, safe, and often completed in one visit.
Benefits of a Pulpotomy
A pulpotomy offers many benefits for children with early tooth infection. It not only relieves pain but also helps protect your child’s growing smile. Some of the main benefits include:
What Is a Pulpectomy?
A pulpectomy is a more advanced pulp therapy treatment for baby teeth. Dentists use it when the infection spreads deeper into the tooth and reaches the root canals.
In this procedure, the dentist removes all the infected pulp from both the crown and roots of the tooth. This helps fully clear the infection and prevent it from spreading.
After removing the pulp, the dentist cleans and disinfects the root canals. Then they fill the space with a special material that safely dissolves as the baby tooth falls out naturally.
A pulpectomy works like a root canal for children and helps save baby teeth with severe infection.
When Does the Child Need a Pulpectomy?
A pediatric dentist may recommend a pulpectomy when the infection has reached the roots and caused more serious symptoms. Your child may need this treatment if:
- The tooth has severe or constant pain
- The pain keeps them awake at night
- There is swelling around the tooth or gums
- A dental abscess forms
- Dental X-rays show infection in the roots or bone
This treatment helps prevent serious infection from damaging nearby teeth or affecting permanent teeth.
How Does a Pulpectomy Procedure Work?
The dentist starts by numbing the area with local anesthesia to keep your child comfortable during treatment.
Then they remove all infected pulp from the crown and root canals. After cleaning the inside of the tooth, they shape the canals and fill them with a safe material made for baby teeth.
Finally, the dentist seals the tooth and places a dental crown to restore strength and function.
Because this procedure treats deeper infection, it may take a little longer than a pulpotomy.
Benefits of a Pulpectomy
A pulpectomy can save a baby tooth even when the infection becomes serious. It removes the infection completely and helps protect your child’s oral health. Some important benefits include:
- Removes deep infection from the entire tooth
- Relieves severe tooth pain and pressure
- Stops infection from spreading to the gums, bone, or nearby teeth
- Saves the baby tooth and avoids early tooth loss
- Protects the space for permanent teeth
- Helps your child chew, eat, and speak normally
- Prevents bigger dental problems and emergency treatment later
A pulpectomy gives children a strong chance to keep their baby tooth healthy until the permanent tooth is ready to come in.
Pulpotomy vs Pulpectomy: The Key Differences
Both treatments save baby teeth, but they treat different levels of infection.
| Feature | Pulpotomy | Pulpectomy |
| Pulp Removed | Only the pulp in the crown | All pulp in the crown and roots |
| Best For | Mild to moderate tooth infection | Severe or deep tooth infection |
| Infection Level | Infection stays in the top part of the tooth | Infection spreads into the roots |
| Tooth Nerve Removal | Partial removal | Complete removal |
| Procedure Type | Less invasive | More detailed and deeper treatment |
| Treatment Time | Usually shorter | Usually longer |
| Pain Relief | Stops pain caused by early pulp infection | Stops pain caused by advanced infection |
| Tooth Restoration | Usually finished with a dental crown | Usually finished with a dental crown |
| Main Goal | Save healthy root pulp and protect the tooth | Remove all infection and save the tooth |
| Chance of Saving the Tooth | High if treated early | High if the tooth structure is still strong |
How Does Your Pediatric Dentist Decide Between a Pulpotomy and Pulpectomy?
A pediatric dentist looks at several things before choosing treatment.
1- Extent of Tooth Decay
The amount of tooth decay is one of the first things the dentist checks.
If the cavity is deep but affects only the crown of the tooth, a pulpotomy may be sufficient. This means the infection has not reached the root canals yet.
If the decay goes deeper and damages the pulp inside the roots, the dentist may recommend a pulpectomy to remove all the infected tissue.
2- Infection Inside the Root
The location of the infection plays a big role in treatment.
If the infection stays in the crown of the tooth, a pulpotomy can save the healthy root pulp.
But if bacteria spread into the roots, the dentist usually chooses a pulpectomy.
This treatment removes the infection from the entire tooth and lowers the risk of the infection spreading to nearby teeth or bone.
3- Dental X-Ray Findings
Dental X-rays help the dentist see what is happening inside the tooth where the eye cannot see.
X-rays can show if the infection has reached the roots, caused damage to the bone, or created an abscess.
They also help the dentist check if the roots are healthy enough to support the tooth after treatment.
This information helps the dentist choose the safest and most effective option.
4- Child’s Symptoms
Your child’s symptoms can give important clues about how serious the infection is.
For example, pain that comes and goes may point to a smaller infection, which may be treated with a pulpotomy.
But constant pain, swelling, pain when chewing, or long-lasting sensitivity can be signs of a deeper infection. In these cases, a pulpectomy may be the better option.
5- Condition of the Baby Tooth
The dentist also checks the overall condition of the baby tooth.
If the tooth still has enough healthy structure, pulp therapy can often save it. But if the tooth is badly broken, weak, or damaged beyond repair, saving it may not be possible.
In some cases, tooth extraction may be the best option to protect your child’s oral health and prevent future problems.
5 Signs Your Child May Need Pulp Therapy
Knowing the signs of tooth infection in children can help you act early.
1- Persistent Toothache
A toothache that does not go away is one of the most common signs of pulp infection.
Your child may complain about pain while eating, drinking, or even resting. Constant or recurrent tooth pain often indicates that the infection has reached the inside of the tooth.
2- Sensitivity to Hot or Cold
If your child feels pain when eating ice cream, drinking cold water, or eating warm foods, the tooth nerve may be irritated or infected.
Sensitivity that lasts for several seconds after eating or drinking can be a sign of deeper tooth damage.
3- Swollen Gums
Swelling around a tooth often means the infection is spreading.
The gums may look red, puffy, or feel sore. In some cases, your child may also feel pain when touching the area.
4- Dental Abscess
A dental abscess is a serious sign of infection.
It may look like a small bump or pimple on the gums near the painful tooth. An abscess can leak pus, causing bad breath, swelling, and severe discomfort.
This needs quick treatment to stop the infection from spreading.
5- Deep Cavities
Large or untreated cavities can reach the pulp inside the tooth.
When this happens, bacteria can infect the nerves and blood vessels inside the tooth, leading to pain and swelling.
Early cavity treatment can often prevent the need for pulp therapy.

What to Expect During the Pulp Therapy Procedure?
Parents often feel nervous when their child needs pulp therapy, but the procedure is usually simple, safe, and comfortable.
The pediatric dentist starts by giving local anesthesia to numb the tooth, so your child feels little or no pain.
Then the dentist carefully removes the decay and infected pulp to stop the infection and protect the tooth.
After cleaning the tooth, the dentist usually places a dental crown, often a stainless steel crown, to restore strength and help the tooth last until it falls out naturally.
According to Verywell Health, a pulpotomy usually takes about 30 to 45 minutes, while a pulpectomy may take a little longer because it treats deeper infection.
