Pulp cells are specialized cells found in the dental pulp, the soft tissue inside a tooth. They play a crucial role in the tooth's health by producing dentin, the hard tissue that forms the bulk of the tooth. Pulp cells are primarily fibroblasts, which help maintain the structure of the pulp and respond to injury or infection. These cells also include immune cells that protect against bacteria and other pathogens. When a tooth is damaged, pulp cells can initiate a healing response, promoting repair and regeneration. Understanding pulp cells is essential for dental health and treatments, such as root canal therapy.
