What is a Pulpotomy?
A pulpotomy is a vital pulp therapy (VPT) procedure that involves the selective removal of infected pulp from a decayed tooth.
During this treatment, only the pulp in the tooth’s crown is removed, while the healthy pulp in the roots is left untouched and preserved. This differs significantly from a root canal treatment, where all of the tooth’s pulp is completely removed.
The primary goal of a pulpotomy is to prevent infection present in one portion of the pulp from spreading to the rest, thereby encouraging tissue regeneration for permanent teeth and ultimately saving the tooth from extraction.
This minimally invasive approach reflects modern dentistry’s recognition of the importance of preserving natural tooth structure and optimizing long-term patient outcomes.

When Do You Need a Pulpotomy?
A pulpotomy may be recommended if you or your child is suffering from a severe cavity where the tooth’s pulp (also known as pulpitis) is infected or inflamed. This procedure is commonly performed on:
- Children with primary (baby) teeth that have deep cavities close to or already extended to a healthy or salvageable pulp
- Adults with permanent teeth experiencing irreversible pulpitis where the infection is confined to the crown pulp
- Patients with damaged teeth due to trauma, where pulp exposure has occurred
Conditions that might indicate the need for a pulpotomy include:
- Deep tooth decay
- Chipped or broken teeth
- Moderate to severe tooth wear
- Tooth abnormalities
- Toothache or dental pain, especially in response to hot and cold stimuli

Benefits of a Pulpotomy
A pulpotomy offers several significant advantages, particularly as a conservative treatment approach:
Preserves Natural Tooth Structure
By removing only the infected portion of the pulp while preserving the healthy tissue, a pulpotomy maintains the tooth’s vitality and natural defense mechanisms.
Promotes Continued Tooth Growth
Especially important for children, a pulpotomy allows the tooth to continue developing normally, particularly if the child is still very young.
Prevents More Serious Complications
A timely pulpotomy can prevent long-term problems such as severe toothache or dental abscess, which would require more invasive treatments like a complete root canal or extraction.
Supports Healthy Oral Development
For children, maintaining primary tooth structure in its proper place allows appropriate space and guidance for future permanent teeth, preventing crowding and encouraging favorable facial and dental development.
Less Invasive Alternative
Compared to root canal treatment or extraction, a pulpotomy is less invasive, preserves more natural tooth structure, and generally causes less discomfort.
Reduced Risk of Root Fractures
As the remaining healthy tissues in the root canal system are preserved, the tooth will not become dried out and brittle, making it less susceptible to root fractures in the future.
Types of Pulpotomy
There are two main types of pulpotomy procedures:
Partial Pulpotomy (PP)
A partial pulpotomy removes only the top-most layer or a small portion of the coronal pulp tissue after exposure. This is followed by applying a biomaterial directly onto the remaining pulp tissue before placement of a permanent restoration.
This approach is particularly suitable for cases where the inflammation is limited to the superficial layers of the pulp.
Full Pulpotomy (FP)
A full pulpotomy involves the complete removal of the coronal pulp and application of a biomaterial directly onto the pulp tissue at the level of the root canal orifice(s) prior to placement of a permanent restoration.
This is generally recommended for cases where it is difficult to judge the scope of infected coronal pulp.

The Pulpotomy Procedure: What to Expect
A pulpotomy procedure typically involves the following stages:
Stage 1: Pre-Treatment Assessment
- A thorough examination including X-rays of the affected tooth will be taken during your check-up appointment
- Your dentist will evaluate your pulp status based on your medical history, clinical manifestations, and radiographic information
- The appropriate type of pulpotomy (partial or full) will be determined based on the diagnosis
Stage 2: The Pulpotomy Procedure
- Anesthesia and Isolation: The relevant tooth will be completely numbed with a local anesthetic to prevent pain during the procedure. A rubber dam will be placed to isolate the tooth and ensure a sterile working environment.
- Removal of Decay: The dentist will remove all carious dentine tissue.
- Pulp Access and Removal: Using a high-speed bur or minimally invasive tool, your dentist will drill through the tooth’s enamel and dentin layers until the pulp is exposed. The infected material within the tooth’s crown will be carefully removed.
- Assessment and Hemostasis: Direct observation of the bleeding surface under magnification helps reassess the pulp status. Hemostasis (bleeding control) is achieved using solutions like sodium hypochlorite, typically controlled within 5-10 minutes.
- Application of Medicament: A biocompatible material such as Mineral Trioxide Aggregate (MTA), iRoot BP Plus, or Biodentine with a thickness of more than 1.5mm is placed over the deeper pulp tissue to encourage healing and viability.
- Final Restoration: The tooth is then restored, usually with a glass ionomer cement base followed by a composite resin filling. In many cases, a tooth-colored or stainless steel crown is placed over the tooth for additional protection.
The entire procedure typically lasts from 30 minutes to 1 hour, depending on the type of tooth, the size of the cavity, and the patient’s cooperation.

Stage 3: Post-Operative Care
After the procedure, your dentist will provide instructions on:
- How to manage any effects from local anesthetic, sedation, or general anesthesia
- Proper oral hygiene practices
- Managing any soreness or discomfort over the next few days (painkillers may be prescribed)
- Follow-up appointments to monitor healing
Most patients recover fully within one to two weeks, with follow-up evaluations recommended at 3 and 6 months to confirm proper healing.

Pulpotomy Materials: Advancements in Dental Technology
Modern pulpotomy procedures benefit from significant advancements in dental materials that promote better healing and regeneration:
Calcium Silicate Cements
These include:
- Mineral Trioxide Aggregate (MTA): Shows excellent sealing ability, biocompatibility, antimicrobial properties, and induces hydroxyapatite formation
- Biodentine: Offers similar biological properties to MTA but with faster setting time and better handling properties
- iRoot BP Plus: A newer nanobioceramic material known for its excellent biocompatibility, antimicrobial properties, flowability, and hydrophilicity
Material Selection Considerations
- MTA is recommended for non-esthetic zones due to its potential for discoloration
- Biodentine and iRoot are suitable choices for use in the anterior aesthetic zone
- Locally developed materials in Singapore and the region often provide excellent performance at more affordable prices
Pulpotomy vs. Other Dental Procedures
Understanding how pulpotomy compares to other dental procedures can help you make informed decisions about your dental care:
Pulpotomy vs. Root Canal Treatment (RCT)
- Pulpotomy: Preserves vital pulp tissue in the roots, maintains tooth sensation and defense mechanisms, requires less tooth structure removal, and is generally less expensive and time-consuming
- Root Canal: Removes all pulp tissue (both crown and root), eliminates tooth sensation, requires more extensive tooth preparation, but may be necessary for cases with more extensive infection

Pulpotomy vs. Pulpectomy
- Pulpotomy: Removes only the coronal pulp while preserving the radicular (root) pulp
- Pulpectomy: Removes all pulp tissue, including that in the root canals
Pulpotomy vs. Pulp Capping
- Pulp Capping: A procedure where a sealing material is placed over a pulp exposure or near-exposure to close off the inner tooth and allow dentin regeneration
- Pulpotomy: Involves the actual removal of infected pulp tissue and is generally considered more predictable for cases with more significant pulp involvement
Risks and Success Rates of Pulpotomy
Potential Risks and Complications
While pulpotomy is generally safe, potential risks include:
- Mild, temporary pain following the procedure due to inflammation
- Infection due to improper healing or inadequate removal of infected tissue
- Tooth discoloration, where the treated tooth may become darker
- Tooth fracture, as a pulpotomy may leave a tooth somewhat weaker (though less susceptible than after root canal treatment)
- Damage to lips and cheeks from accidental biting while the area is still numb
Success Rates
Based on current evidence, pulpotomy demonstrates impressive success rates:
- For permanent teeth with irreversible pulpitis, pulpotomy yields clinical and radiographic success rates comparable to those of root canal treatment
- Studies show success rates ranging from 85-99% for procedures using modern biomaterials like MTA and Biodentine
- The formation of a reparative dentin bridge correlates with higher success rates
Pulpotomy in Children vs. Adults
Pulpotomy for Children
- Commonly performed on primary (baby) teeth to avoid premature tooth loss
- Helps maintain space for permanent teeth and guides proper dental development
- Often completed with a stainless steel crown for durability
- Very high success rates in properly selected cases
Pulpotomy for Adults
- Increasingly supported by research as a viable alternative to root canal treatment
- Particularly valuable for permanent teeth with irreversible pulpitis where the infection is confined to the coronal pulp
- May allow delaying or avoiding more extensive procedures
- Recent studies show comparable success rates to traditional root canal treatment

Frequently Asked Questions about Pulpotomy
How painful is a pulpotomy procedure?
The pulpotomy procedure itself should not be painful as it is performed under local anesthesia.
You may experience some mild discomfort or soreness for a few days after the procedure, which can typically be managed with over-the-counter pain relievers.
Compared to alternatives like extraction or root canal treatment, pulpotomy is generally considered less painful and has a smoother recovery.
How long does a pulpotomy take?
A pulpotomy procedure typically takes between 30 minutes to 1 hour, depending on the type of tooth being treated, the extent of decay, and the patient’s cooperation.
In some cases, your dentist may split the procedure into multiple visits.
How much does a pulpotomy cost in Singapore?
The cost of a pulpotomy in Singapore varies depending on factors such as the clinic, the dentist’s expertise, the type of materials used, and whether additional treatments (like crowns) are needed.
Generally, pulpotomy is more affordable than root canal treatment. Singapore citizens and permanent residents may also qualify for subsidies through various healthcare schemes.
Is pulpotomy suitable for adults?
Yes, pulpotomy is increasingly recognized as a suitable treatment for adults with irreversible pulpitis.
Recent research supports pulpotomy as a viable alternative to root canal treatment for mature permanent teeth, especially when the pulp infection is confined to the crown portion of the tooth.
What is the difference between pulpotomy and root canal?
The main difference is the amount of pulp tissue removed. In a pulpotomy, only the infected portion of the pulp in the tooth’s crown is removed, while the healthy pulp in the roots is preserved.
In a root canal, all pulp tissue (both in the crown and roots) is completely removed. Pulpotomy aims to maintain the tooth’s vitality, while root canal treatment results in a non-vital tooth.
How long does a tooth last after pulpotomy?
With proper care and regular dental check-ups, a tooth that has undergone pulpotomy can last for many years or even a lifetime.
The success rate is particularly high when modern biocompatible materials are used and when the procedure is performed under optimal conditions.
Can a tooth with pulpotomy get infected?
While uncommon, it is possible for a tooth that has undergone pulpotomy to develop an infection if the remaining pulp becomes infected or if the restoration fails to provide an adequate seal.
Signs of infection include persistent pain, swelling, or the development of an abscess. If you notice any of these symptoms, contact your dentist immediately.
Is pulpotomy better than extraction?
In most cases, preserving natural teeth through procedures like pulpotomy is preferable to extraction. Keeping your natural teeth helps maintain proper chewing function, prevents shifting of adjacent teeth, and preserves bone structure. However, each case is unique, and your dentist will recommend the most appropriate treatment based on your specific situation.
Do I need a crown after pulpotomy?
In many cases, especially for posterior teeth that bear significant chewing forces, a crown is recommended after pulpotomy to provide additional protection and prevent fracture.
For anterior teeth or those with minimal structural compromise, a durable filling may be sufficient.
Can a pulpotomy fail?
Yes, like any dental procedure, pulpotomy can fail in some cases. Factors that might contribute to failure include inadequate removal of infected tissue, bacterial leakage around the restoration, or progression of the infection into the root pulp.
Regular follow-up appointments allow your dentist to monitor the treated tooth and address any issues promptly.
Conclusion
Pulpotomy represents a significant advancement in dental care, offering a minimally invasive approach to treating pulp infections while preserving natural tooth structure and function.
Whether for children with primary teeth or adults with permanent teeth, this procedure provides an excellent alternative to more extensive treatments when appropriate.
With ongoing advancements in diagnostic techniques, materials, and clinical protocols, pulpotomy continues to evolve as an essential component of modern dentistry in Singapore.
By preserving the vital tissues of the tooth, pulpotomy not only addresses immediate dental concerns but also supports long-term oral health and wellbeing.
If you’re experiencing dental pain or have been told you might need a root canal, consider discussing the possibility of pulpotomy with your dentist. This conservative approach might be the key to saving your natural tooth while minimizing intervention.
