Introduction: the dentin hypersensitivity (HSDC) is characterized by loss of enamel and cementum in the cervical region of the teeth and the consequent exposure of dentinal tubules leading to a painful and uncomfortable for the patient. Objective: This study aimed to address the etiological factors, prevalence and various forms related to cervical dentin hypersensitivity treatment. Literature review: Being reported with a prevalence of about 30% of the population, this loss of tooth structure occurs due to the formation of cervical lesions by processes of gingival recession, abrasion, erosion, abfraction or association of two or more factors. The knowledge of the etiology of any disease or oral condition is paramount for safe and effective treatment, so this literature review is to inform the etiology, prevalence, and treatment options for dentin hypersensitivity, through a literature review of national and international data-bases (pubmed, scielo, bireme and cochrane). Some medical treatments have to be effective, such as application of potassium oxalate, strontium chloride, fluorinated coatings, sodium fluoride, low power laser, desensitizing dentifrice systems, adhesives and restorative procedures. Final considerations: Therefore, the identification and removal of etiological factors are essential to the successful treatment of HSDC when associated with obliteration of the dentinal tubules, resulting in the effective reduction of the movement of the fluid within the tubules and decreased pain.
