Dentine hypersensitivity (DH) is one of the most common clinical problems which can cause considerable discomfort to the patients. Once initiated it can cause sensitivity or can trigger pain and create severe discomfort for the patient. Gingival recession and enamel loss both, resulting in the exposure of dentine, contribute to the prevalence of this condition. Dentine 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 Brannstrom’s Hydrodynamic Theory. Its management requires a good understanding of the complexity of the problem, there are a variety of treatments available to treat DH. This review describes the etiology, incidence and management of dentine hypersensitivity.
