Repeated exposures to a low pH cause the mineral content of the teeth on the outer layer of enamel to dissolve therefore leaving the dentine exposed and leading to hypersensitivity. Other causes include dental bleaching, smoking tobacco (which can lead to recession and therefore sensitivity) cracked teeth and abfraction or grinding of teeth ...
Dr.Brännström (1922-2001) was a Swedish dentist, specialising in Oral Pathology and the mechanism of tooth sensitivity. [22] In the 1960s, Brännström provided evidence to support Gysi's hydrodynamic theory through a series of experimental studies in vitro to show that various stimuli caused shifts in fluid movement across dentine, producing ...
A tooth is composed of an outer shell of calcified hard tissues (from hardest to softest: enamel, dentin, and cementum), and an inner soft tissue core (the pulp system), which contains nerves and blood vessels. The visible parts of the teeth in the mouth – the crowns (covered by enamel) – are anchored into the bone by the roots (covered by ...
Teeth affected by MIH are often affected by hypersensitivity due to changes in temperature or tooth brushing. A study has suggested that a possible cause of hypersensitivity in MIH is the inflammatory reactions in the pulp due to oral bacteria penetrating through the hypomineralised enamel into the dentinal tubules.

Sensitivity tests assess the sensory response of a tooth to an external stimulus, results which may be extrapolated to indirectly determine pulpal health status. Sensory stimuli, such as heat, cold or an electrical current, are applied to the tooth in question in order to stimulate the nocireceptors within the pulp. The type of sensory fibres ...
According to both dentists, some whitening strips can cause sensitivity and pain in the teeth, gums and jaw. They can also cause irritation, inflammation and discoloration, as there’s a chance ...
"Tooth whitening can cause sensitivity and gum irritation," Goldman says. Yazdani agrees, adding that it can also occur if teeth whitening strips or gel trays are left on for too long.
Silver diammine fluoride (SDF), also known as silver diamine fluoride in most of the dental literature (although this is a chemical misnomer), is a topical medication used to treat and prevent dental caries (tooth decay) and relieve dentinal hypersensitivity. [1]
