Dental sensitivity or sensitive teeth, is a disorder characterized by the gradual exposure of the dentine, the soft and delicate part of the tooth that is located under the enamel. The dentin presents the tubules (small tubes) filled with a fluid which in turn contains many nerve endings. The introduction of excessively hot, cold, sweet or acid foods or beverages in the mouth can in case of exposed dentin, cause a displacement of this liquid, that stimulates the reaction of the nerve endings, with the consequent onset of discomfort or acute pain .

Teeth grinding is also equally harmful. Dental sensitivity can also be a symptom of other diseases (caries, gingivitis and pulpitis).
