Not every tooth with an infected or inflamed pulp needs a full root canal. In specific clinical situations — particularly in children’s primary teeth and in young permanent teeth with incomplete root development — a pulpotomy offers a more appropriate and biologically conservative approach. A pulpotomy removes only the inflamed pulp tissue in the crown of the tooth while preserving the healthy pulp in the roots, maintaining the tooth’s vitality and allowing continued root development where this is clinically important. At Al Safwa Medical Center in Bani Yas, Abu Dhabi, the pulpotomy procedure is performed by the endodontics and pediatric dentistry teams depending on the patient’s age and the clinical context.
This guide explains what a pulpotomy is, how it differs from a full root canal treatment, when it is the appropriate choice, and what the procedure involves. For broader context on endodontic treatment including root canal procedures, the endodontics hub guide provides a comprehensive overview.
What is a pulpotomy?
A pulpotomy is a partial pulp treatment — the inflamed or infected pulp tissue in the crown of the tooth (the coronal pulp) is removed, while the pulp in the root canals (the radicular pulp) is left in place provided it shows clinical signs of health and vitality. A medicament — most commonly a biocompatible material such as mineral trioxide aggregate (MTA) or ferric sulphate — is placed over the remaining pulp stumps at the canal entrances to promote healing and prevent further infection. The access cavity is then sealed with a filling, and typically a crown is placed over the tooth to protect it.
The key distinction from a full root canal treatment is that a pulpotomy does not remove the radicular pulp — the living tissue in the root canals is preserved. This is appropriate only when the radicular pulp is healthy and the inflammation or infection is genuinely limited to the coronal portion.
When is a pulpotomy the right treatment?
Primary (baby) teeth in children
Pulpotomy is the most common endodontic treatment for primary teeth. When a primary tooth has deep decay that has reached or is very close to the pulp — causing pain or spontaneous bleeding on excavation — a pulpotomy preserves the tooth until its natural exfoliation time, maintaining the arch space for the permanent tooth beneath. Full root canal treatment is not typically performed on primary teeth because the complex root anatomy of primary molars and the physiological resorption process make thorough canal cleaning difficult and the outcome less predictable.
Preserving primary teeth with pulpotomy is important because premature loss of a primary molar requires a space maintainer to prevent arch collapse. The primary tooth — even treated — is the best natural space maintainer available. The guide to pediatric dentistry in Abu Dhabi covers the broader context of why treating primary teeth matters.
Young permanent teeth with open apices (vital pulp therapy)
Permanent teeth continue root development for several years after eruption — a process called apexogenesis. During this period, the root walls are thin and the root tip is still forming. If a young permanent tooth develops pulp inflammation from decay or trauma while the root is still developing, a pulpotomy (or the related procedure called a partial pulpotomy or Cvek pulpotomy) can remove only the directly affected pulp tissue while preserving the remaining healthy pulp — allowing root development to continue toward full maturity. A fully developed root is significantly stronger and more resistant to fracture than an incompletely formed one, making preservation of vitality during this developmental window of major clinical value.
Mature permanent teeth with carious exposure (vital pulp therapy in adults)
There is growing clinical evidence and increasing clinical adoption of vital pulp therapy in mature permanent teeth — performing a partial or full coronal pulpotomy rather than a full root canal in cases of carious pulp exposure where the radicular pulp is assessed to be healthy. When MTA or biodentine is used as the pulp capping material, clinical success rates in properly selected cases are high. This represents a more conservative approach to pulp treatment that is becoming an evidence-supported alternative to root canal treatment in specific circumstances. Your endodontist at Al Safwa will assess whether a pulpotomy is appropriate for an adult tooth or whether full root canal treatment is more clinically appropriate for your specific situation.
How the pulpotomy procedure works
Anaesthesia. Local anaesthesia is administered. For children, the Al Safwa pediatric dentistry team uses a behavioural management approach designed to make the procedure as comfortable and anxiety-free as possible.
Rubber dam placement. A rubber dam isolates the tooth from the oral environment, creating a sterile field for the procedure.
Access and coronal pulp removal. An access cavity is prepared through the crown of the tooth. The coronal pulp is removed using a round bur or excavator. Haemostasis is achieved at the canal entrances — the amount and character of the bleeding from the remaining radicular pulp stumps is assessed to confirm they are healthy.
Medicament placement. A biocompatible medicament — typically MTA, biodentine, or formocresol in primary teeth — is placed over the pulp stumps. MTA and biodentine promote healing and dentine bridge formation. Formocresol is a more traditional material used in primary teeth that causes fixation of the remaining pulp rather than regeneration.
Restoration. The access cavity is sealed with a base and a filling. In primary molars, a stainless steel crown is typically placed over the tooth at the same visit or shortly after, providing durable coverage for the remaining treatment period. In permanent teeth, a definitive restoration — composite filling or crown depending on the amount of remaining tooth structure — is placed.
Pulpotomy vs root canal treatment: key differences
| Feature | Pulpotomy | Root Canal Treatment |
|---|---|---|
| Pulp removed | Coronal pulp only | All pulp (coronal and radicular) |
| Tooth vitality preserved | Yes — root pulp remains | No — tooth becomes non-vital |
| Root development | Can continue (young teeth) | Stops (root pulp removed) |
| Most common use | Primary teeth, young permanent teeth | Permanent teeth with irreversible pulpitis |
| Treatment time | Typically one appointment | One to two appointments |
| Post-treatment restoration | Stainless steel crown (primary) or composite/crown (permanent) | Crown typically recommended |
Can a pulpotomy fail?
Pulpotomy success depends primarily on the accuracy of the diagnosis — specifically whether the remaining radicular pulp was genuinely healthy at the time of treatment. If the inflammation extended into the root canals at the time of treatment, the pulpotomy will not resolve the problem and the tooth may develop continued pain or a periapical abscess. In this situation, a full root canal treatment becomes necessary. Clinical signs of pulpotomy failure include persistent pain, swelling, or radiographic evidence of pathology at the root tips developing after treatment. Follow-up radiographic review at intervals is important to confirm successful healing.
Tooth pain in a child? Concerned about a young permanent tooth?
At Al Safwa Medical Center in Bani Yas, Abu Dhabi, pulpotomy is performed by both the pediatric dentistry team for primary teeth and the endodontics team for permanent teeth where vital pulp therapy is indicated. The decision between a pulpotomy and a full root canal is made after careful clinical assessment — including radiographs and evaluation of the pulp’s response — to select the treatment that gives the best long-term outcome for the specific tooth.

Frequently asked questions
What is the difference between a pulpotomy and a root canal?
A pulpotomy removes only the pulp tissue in the crown of the tooth while preserving the living pulp in the root canals. A root canal removes all the pulp — from the crown and all the root canals. A pulpotomy is appropriate when the inflammation is limited to the coronal pulp and the radicular pulp is healthy; a root canal is needed when the entire pulp is affected or non-vital.
Is a pulpotomy painful?
The procedure is performed under local anaesthesia and is not painful during treatment. For children, the pediatric dentistry team uses a gentle, child-focused approach to minimise anxiety and discomfort. Most children tolerate pulpotomy very well. Some mild sensitivity for a day or two after the procedure is possible but typically resolves quickly.
Does my child need a crown after a pulpotomy?
Yes, in the great majority of cases. A stainless steel crown is placed over a primary molar after pulpotomy to protect the remaining tooth structure, which has been significantly weakened by the original decay and the access cavity. The crown also protects the pulpotomy medicament and maintains the tooth’s shape and function until natural exfoliation. Clinical studies consistently show that teeth with pulpotomy and crown have significantly better long-term outcomes than those restored with filling alone.
How long does a pulpotomy take?
A pulpotomy is typically completed in a single appointment of 45 to 60 minutes. If a stainless steel crown is placed at the same visit — which is often the case in primary teeth — the total appointment time may be 60 to 90 minutes. For permanent teeth, the definitive restoration may be placed at a separate appointment.
Can pulpotomy be done on adult teeth?
Yes. Vital pulp therapy — including partial or full coronal pulpotomy — in mature permanent teeth is an evidence-supported option in carefully selected cases where the diagnosis confirms reversible pulpitis or carious exposure with a healthy radicular pulp. The success of this approach depends heavily on accurate diagnosis and appropriate case selection. Your endodontist will assess whether it is appropriate for your tooth or whether full root canal treatment is more indicated.
