What we call the 'nerve' is actually living tissue
The dental pulp contains nerves, blood vessels, and connective tissue. Vital pulp therapy aims to preserve its living function. Root canal treatment takes a different approach, removing inflamed or infected pulp and cleaning and filling the inside of the tooth.[1][4]
This also differs from selective caries removal, in which some decay is left to avoid exposing the pulp. Here, the focus is on assessing whether living tissue can be preserved once the pulp has been exposed, for example during decay removal.
Covering the exposure and removing some pulp are different options
Options include direct pulp capping, which covers exposed pulp with a protective material, and partial or full coronal pulpotomy, which removes some or all pulp in the crown while retaining deeper tissue. The American Association of Endodontists describes vital pulp therapy as a range of approaches rather than a single procedure.[1]
The word “pulpotomy” does not mean that all pulp is removed from the roots. Equally, simply covering a small area is not a solution for every tooth. The extent of treatment depends on which tissue can be retained, so ask which part would be treated in your case.
Pulp condition and treatment circumstances matter more than age alone
Vital pulp therapy may be considered in selected mature permanent teeth with fully developed roots, but necrotic—dead—pulp is not a candidate. Assessment combines the pain history, tests and imaging, and findings during treatment, including tissue appearance and control of bleeding.[1][2]
Pain alone cannot determine eligibility, and a single X-ray cannot promise success. Isolating the tooth from saliva and minimizing contamination are also important. The plan may need to change if the conditions for preserving the pulp are not suitable.[2]
Encouraging results still come with limits in the evidence
A 2024 systematic review brought together 25 randomized trials of pulpotomy in permanent teeth with carious pulp exposure. Although the findings supported the potential for preservation, the authors rated the certainty of evidence as very low to low.[3]
The studies differed in tooth condition and treatment materials, and many compared materials or the extent of pulpotomy. They were not 25 direct comparisons with root canal treatment. Their combined results cannot establish that your tooth will certainly succeed or that this approach is always better than root canal treatment.
What happens after preserving the pulp is part of treatment too
The tooth needs a well-sealed restoration and follow-up after living tissue is retained. Leakage can allow further contamination. Ask how a temporary covering differs from the final restoration, and agree on a schedule for reassessment with your dentist.[1][2]
Root canal treatment may become necessary if healing is unsatisfactory. That does not automatically mean losing the tooth: root canal treatment is also intended to retain natural teeth. Understand both the opportunity to preserve the pulp and the alternatives before deciding.[4]
