Tooth sensitivity is also known as Dentin Hypersensitivity. It affects the tooth or exposed root surfaces. This occurs when the enamel that protects our teeth gets thinner, or when gum recession occurs, exposing the underlying surface (dentin), thus, reducing the protection the enamel & gums provide to the tooth & root. According to the studies, Tooth Sensitivity affects up to 57% of the population globally.
