This article reviews dentin sensitivity from a mechanistic perspective beginning with short treatments of pulpal innervation, the hydrodynamic considerations of dentin, and how various stimuli may cause pain. Speculation is raised about the contribution of bacteria and their products on dentin sensitivity and how dentin might become truly hypersensitive, especially following periodontal therapy. Wherever possible, the clinical considerations of basic research is stressed.
