The survival time of dental pulp following injury or interruption of its blood supply is variable and depends on several factors. The vitality of the pulp, which contains the nerve, is affected by the extent of the trauma, the individual’s overall health, and the presence of infection. In cases of significant trauma, such as a fracture exposing the pulp, or a deep cavity reaching the nerve, the pulp’s demise can occur rapidly potentially within a few days to a few weeks.
Preserving pulp vitality is crucial for maintaining tooth strength and its ability to sense temperature changes and pressure. The pulp provides essential nutrients and hydration to the tooth structure. Historically, extractions were the primary treatment for pulp damage; however, modern endodontic procedures, such as root canal therapy, aim to remove the infected or necrotic pulp while saving the tooth.
