Indirect Pulp Therapy

Indirect pulp therapy, also known as indirect pulp capping, is a procedure performed on a tooth where solely the outer dentin layers are affected by an infection, while the inner pulp of the teeth is unaffected and healthy.


It is a minimally invasive procedure that is meant to protect and restore a tooth, by reducing risk of exposure to the tooth's pulp. 


It is mainly performed on children, and is suitable for primary teeth and young permanent teeth that are developing incorrectly.

What is Indirect Pulp Therapy?

In indirect pulp therapy, the pulp tissue is left untouched and covered with a biocompatible material, to prevent microleakage.


It is a minimally invasive alternative to an invasive techniques like pulpotomy. Unlike other methods, there is no reopening of the cavity for the treatment of deep caries lesions.


Long term retention of permanent molars requires a root with a favourable crown to root ratio and dentinal walls that are thick enough to function well.

What Does the Procedure Involve?

Stage 1: Pre-Treatment

  • To remove infected dentin, a bactericidal liner needs to be applied, such as calcium hydroxide, over the remaining carious dentin.
  • This is to induce tertiary dentin (or reparative dentin) formation, protect the dental pulp tissue and stimulate healing and repair.
  • This aids in the enhancement of the restorative material and tooth structure interfacial seal and for allowing adequate control of microleakage.


Stage 2: Indirect Pulp Therapy Procedure

  • Indirect pulp therapy is a supplementary procedure in addition to placing a dental filling (composite resins). Just before your filling is placed, a layer of medication will be used to line the base of the cavity overlying your pulp.
  • The medication has an anti-bacterial and soothing effect to help protect and heal your pulp, thereby preserving its health and vitality. The tooth is then restored with a material that seals the tooth from microleakage.

What Are the Risks Involved?

Indirect pulp therapy is a supplementary treatment procedure to a filling that is commonly performed and is generally considered safe.
  • As much as it aims to heal and soothe your pulp, a slight chance remains that your pulp condition may deteriorate in the future which may require a root canal treatment or extraction to address. However, in deep cavities with a healthy pulp, it is often worth attempting an indirect pulp therapy followed by a simple filling first as this is less invasive. 
  • The success of the treatment depends on the complete removal of decay from the walls of the cavity.
  • f you are allergic to any known material (e.g. plasters), please inform our dentists beforehand so that we can plan the material to use to avoid any allergic reactions.
