Dentinal hypersensitivity is characterized by a short, sharp pain in response to stimuli. Dentinal hypersensitivity, which is more commonly seen in adults in the 20- to 40-year-old age group, has several etiological factors. Gingival recession and enamel loss both contribute to the prevalence of this condition, resulting in the exposure of dentin. Dentinal hypersensitivity is believed to occur due to the movement of fluid within the dentinal tubules occurring in response to thermal, chemical, tactile, and evaporative stimuli, in accordance with Brännström’s hydrodynamic theory. Treatment options include in-office procedures and home-use products that are aimed at occluding the dentinal tubules or preventing neural transmission, thereby blocking the pain response.
