Are you suffering from sensitive teeth?
Tooth sensitivity or known as dentin hypersensitivity is short or transient sharp pain of a rapid onset that arises from exposed dentin layer of one or more teeth subsequent to loss of tooth structure (enamel layer of the crown or cementum layer of the root). It usually occurs in response to stimuliâ€”typically cold, air pressure, drying, sugar, acids, chemicals or forces acting onto the toothâ€”and cannot be ascribed to any other dental defects or pathology. These stimuli are non-noxious, and are not generally expected to generate a pain response, except as seen in sensitive teeth. In contrast, a noxious stimulus would be the toxins of bacteria within a decay lesion leading to dentinal pain. Areas of exposed dentin at the junction between the crown and the root (cervical area) account for much of the observed tooth sensitivity. Continue reading
