The main four functions of the pulp are formation and nutrition of the dentin, as well as the innervation and defense of the tooth. Dentin formation is one of the most critical roles carried out by the pulp and, as mentioned, is formed by the odontoblasts. The pulp also plays a nutritive role in supporting the dentin with moisture and nutrients such as albumin, transferrin, tenascin, and other proteoglycans.

The pulp also plays a nutritive role in supporting the dentin with moisture and nutrients such as albumin, transferrin, tenascin, and other proteoglycans.The defensive role of the pulp occurs through the development of new dentin, which can provide a barrier between irritants and slow the rate of carious decay. This process is mediated by the pulp, which spurs odontoblasts into action or initiates the production of new ones to form this needed hard tissue. The type and amount of dentin produced depend on numerous factors, including the source of damage (pathogen, thermal, chemical), the depth of damage, its severity, and the amount of surface area involved. The fact odontoblasts underline the significance of the pulp in dentin formation do not participate in cell division. Consequently, the formation of additional dentin relies on the pool of undifferentiated mesenchymal populations in the cell-rich zone to replace them
