Dentin hypersensitivity is the common diagnosis of short, sharp pain occurring in exposed dentin due to thermal, evaporative, tactile, osmotic, or chemical stimuli, etc. [1]. The dentin consists of a number of tubules that connect the dentin-enamel junction to pulpal nerve fibers, varying in size and orientation [1], [2]. Dentin tubules become exposed due to gingival recession or enamel erosion, leaving the pulpal nerve fibers at a risk of stimulation due to dentinal fluid movement or other pain provoking stimuli [1], [2]. The diagnosis of dentin hypersensitivity occurs most frequently in 20 to 30 year-olds, with more than 40 million people in the US reported to be effected [1]. Due to the prevalence and the large number of years, scientists have known about dentin hypersensitivity, there have been many treatments developed to combat it.
