← All explanationsDirect pulp capping

Can an exposed pulp stay alive?

Direct pulp capping places a suitable material over an exposed area of living pulp. The aim is to preserve the tissue. Suitability depends on the findings, and success is not guaranteed.

01 / 03

Assess the pulp

History, symptoms and clinical findings matter. Exposure alone does not determine the procedure.

02 / 03

Cover directly

In suitable circumstances, the capping material contacts the exposed pulp. The tooth then needs an effective restoration seal.

Review the response

Agreed reviews assess progress. Persistent or new symptoms may require different treatment.

Often confused

Direct versus indirect

Direct capping contacts exposed pulp. With an indirect approach, dentine remains between pulp and restoration.

Quick answers

Is this a root filling?

No. Capping aims to retain living pulp; root filling seals prepared canals.

Which material is used?

Suitable dental biomaterials include hydraulic calcium silicate cements. The treating team selects the material.

Is healing then certain?

No. Capping can fail, so follow-up and reporting new symptoms matter.

For a personal discussion

Editorially suggested question to discuss with Dr Niusha Barahmand Pour:

Which findings support or argue against preserving the pulp in my tooth?

A deep lesion deserves a discussion of the possibilities and limits of tooth preservation.
