Also known as dental hypersensitivity, it consists of sharp pain that occurs in a specific area of the mouth. It is noted as a short but very uncomfortable hole, triggered by an external stimulus such as contact with cold or heat directly on the tooth.
While the parts of the teeth are often protected from these types of uncomfortable sensations, when the inside of the tooth, the dentin, becomes unprotected and comes into contact with any external stimulus, pain occurs that can vary in intensity and duration.
Denidine is the tooth tissue beneath the enamel and contains thousands of dentin tubules, which somehow connect the outside of the tooth to the nerve endings on the inside. When dentin is exposed, external stimuli such as cold or heat are perceived by the nerve from the tooth producing tooth sensitivity.
According to the Madrid College of Health definition of dentin hypersensitivity, the external stimuli produced by it can be thermal, chemical or tactile. The level of sensitivity varies depending on the type and location of damage to the tooth enamel.
