Sensitive teeth causes
The term of sensitive teeth refers to the dental hypersensitivity, an annoyance that can vary in intensity and is caused by heat and cold (hot dishes and cold drinks). Both excess heat and cold directly attack the teeth and in particular, to dentine, tissue located between the top enamel of the tooth and the pulp. The dentine forms the greater part of the tooth and is responsible to protect the pulp.

Dentine consists of so-called microtubules, which contain essential cells for its maintenance, the extracellular fluid that is essential for the transmission of stimuli to nerve receptors that are found in the tooth.




The extracellular fluid activates the microtubules and triggers the annoying reaction as a result of thermal or tactile stimulation from the outside.

Causes
Heat and cold are responsible for sensitive teeth, but the causes are different. Sensitive teeth tend to be the result, in the majority of cases, the removal or loss of enamel which covers the crown. The discomfort will appear when taken acidic foods, carbonated beverages, citrus, vinegar and wine.
