In addition, dental caries is more likely to develop pulpitis due to less time for the dental pulp to react and protect itself by occluding the dentinal tubules. Based on the tooth injury, sensory nerve fibers react to pulpitis by growing terminal branches into the adjacent surviving pulp, which also changes the cytochemical phenotype. This neural growth typically lasts few a few days and function and form is retained. Thus, pain is poorly localized, and the level of pain stemming from pulpitis varies based on severity, quality, duration, onset, trigger.
