When a tooth's pulp is exposed but still alive and healthy, sealing it with a modern bioceramic material can let the tooth keep its own blood supply and nerve — avoiding a root canal entirely. This is the patient guide to when that works, when it doesn't, and what the AAE-endorsed evidence actually shows.
Three procedures sit under the VPT umbrella. Which one is right depends on how deep the exposure is and what the surrounding pulp tissue looks like under the microscope.
A thin layer of remaining dentin is left over the pulp and sealed with a bioceramic liner. Used when caries is deep but no actual pulp exposure has occurred.
A small (~1 mm) pulp exposure is sealed directly with MTA or Biodentine, then restored. Used for mechanical or carious exposure with limited bleeding and clinically healthy pulp.
The coronal pulp tissue is removed and the remaining radicular pulp is sealed with bioceramic. Endorsed by the AAE 2021 as a definitive treatment in select cases of irreversible pulpitis with normal periapical findings.
Mishra and colleagues randomized 104 mature permanent molars to partial pulpotomy using either sodium hypochlorite (NaOCl) or chlorhexidine (CHX) lavage. Among 99 teeth assessed at 12 months, reported success was 91.8% with NaOCl and 84% with CHX. The difference was not statistically significant.[7]
These results concern selected teeth followed for 12 months, not a long-term guarantee. The trial compared two lavage solutions during partial pulpotomy; it did not compare pulpotomy with root canal treatment.

Vital pulp therapy is not a workaround — it is a genuine treatment with specific indications. The wrong tooth doesn't just fail VPT; it loses the window for a clean root canal.
A 2026 systematic review and meta-analysis in Scientific Reports (Hoang et al.) evaluated pulpotomy in mature permanent posterior teeth diagnosed with irreversible pulpitis and found favorable outcomes at 12 months — though the authors noted low-to-very-low certainty across the included studies and called for longer follow-up before drawing definitive conclusions.[4]
A 2026 systematic review and meta-analysis of 42 studies found pulpal calcification after vital pulp therapy in 8.8% of treated teeth and found no association between calcification and treatment success (odds ratio 1.01; 95% confidence interval, 0.43–2.38). The evidence for that comparison was very low certainty, so it does not predict an individual tooth’s outcome. This finding concerns calcification that develops after pulp therapy, not a pre-existing calcified canal, and it does not make VPT appropriate for every tooth.[6]
Vital pulp therapy is done under the same microscope, isolation, and irrigation protocols as a root canal — the difference is what we leave behind, not what we do during the visit.
Cold test, electric pulp test, percussion, and palpation. CBCT 3D imaging when periapical findings are unclear on 2D X-ray.
Full anesthesia, then dental dam isolation — exactly the same standard-of-care protocol as a root canal. Skipping the dam contaminates the exposure site and changes the prognosis.
All carious dentin is removed under the Zeiss OPMI surgical microscope (up to 25× magnification). If exposure occurs, we assess bleeding character and time-to-hemostasis — those two findings drive the next decision.
Depending on exposure size and pulp appearance: indirect cap, direct cap, partial pulpotomy, or full coronal pulpotomy. The exposed pulp is sealed with MTA or Biodentine — a bioceramic that bonds to dentin and stimulates a calcified bridge over time.
A bonded composite or glass-ionomer restoration is placed over the bioceramic at the same visit. Definitive coronal sealing is the single biggest predictor of long-term VPT success.
Recheck at 3, 6, and 12 months: vitality testing, percussion, and a periapical X-ray. If the pulp later becomes non-vital, conventional root canal treatment is still entirely feasible — VPT does not burn that bridge.
In well-indicated cases — yes. The AAE 2021 Position Statement supports VPT as a definitive treatment, not merely a temporary measure. Pulp survival at 1–3 years with modern bioceramic materials is reported at 80–95% in randomized trials. The honest caveat: case selection matters more than technique. The wrong tooth fails VPT and needs a root canal anyway.
Not always. Smaller restorations on premolars and molars can be sealed with a well-bonded composite. Larger restorations, or any tooth that has lost a marginal ridge, typically still need a cusp-coverage onlay or crown to prevent fracture — separately from the VPT itself.
If the pulp later becomes non-vital, conventional root canal treatment is straightforward — VPT does not damage the canal anatomy or compromise the prognosis of a future RCT. We typically diagnose failure on follow-up vitality testing or X-ray before symptoms develop.
VPT requires a microscope, strict isolation, bioceramic materials, and a rigorous follow-up protocol. The technique is also relatively new at this level of evidence — the strongest support is from research in the last 10–15 years. Many general dentists offer indirect pulp caps; full pulpotomy as a definitive treatment is more typically offered by endodontists.
Both materials are bioceramic calcium-silicate cements with excellent published outcomes. MTA has a longer track record (since the 1990s); Biodentine sets faster (~12 minutes vs. several hours) and is easier to place. We use both — the choice depends on the clinical scenario, not on one being categorically superior.
Most PPO plans cover the relevant CDT codes (D3110 direct pulp cap, D3220 pulpotomy) and the accompanying restoration. Coverage is generally similar to a deep filling — typically less than a full root canal. We provide a written pre-treatment estimate before any work begins.
If your dentist has told you that you need a root canal but the tooth is still vital and only mildly symptomatic, a vital pulp therapy consultation may be worth the visit. Dr. Kung will review your X-rays, run vitality testing, and tell you honestly whether VPT is a reasonable option for your specific tooth — or whether a conventional root canal is the better long-term path.
