If caries progresses to the pulp, it can cause infection and inflammation of the dental nerve. In such cases, an endodontic procedure, i.e., root canal treatment, is performed.
The most common reasons for endodontic treatment of primary teeth include deep caries that has reached the dental pulp, trauma (tooth impact or fracture), and the presence of an abscess or gum swelling. The goal of the therapy is to eliminate the infection, reduce pain, and allow the tooth to remain in place until the permanent tooth erupts, thereby maintaining proper bite and jaw development.
Pulp treatment of primary teeth can be a highly complex procedure considering the duration and the child's cooperation. Various pulpotomy methods are most commonly applied, and if there is recurrent inflammation, pulpectomy and root canal instrumentation are performed, as with permanent teeth.
