In a healthy tooth, a coating of enamel protects the crown — the part above the gum line — and a layer of cementum protects the tooth root below the gum line. Enamel and cementum are inert (nonliving) substances that do not respond to stimuli such as heat or cold; however, dentin, the living tissue below them, does. Dentin contains numerous microscopic tubules that readily transmit stimuli toward the nerve-filled center of the tooth (pulp tissue). Loss of protective enamel or cementum leaves dentin exposed to all sorts of stimuli in the oral environment, which can trigger “dentinal hypersensitivity” — anything from a mild twinge to shooting pain.
Fortunately, there are many options for treating hypersensitivity. The key to selecting the most appropriate one(s) is determining the cause(s). Some of the more common reasons for sensitivity due to dentin exposure include:
Sensitivity can also occur following a procedure like treating a cavity. Normally it subsides within a couple of weeks or so but if it continues there may be another underlying cause.
Whatever the source(s) of your discomfort, our office can get to the bottom of it and recommend an effective course of treatment that meets your personal needs!
