When
cement or dentine become exposed because of gingival recession or
enamel loss, an external tactile, thermal or chemical stimulus can
trigger a painful feeling that, under normal conditions would not be
bothersome at all.

Dental sensitivity is a painful
condition that can become chronic. It can sometimes be very painful and
unpleasant. This transitory pain is a consequence of the exposure of
dentine to chemical, osmotic, thermal or tactile stimuli and cannot be
associated with any other dental pathology. Some people tolerate this
hypersensitivity whereas for other people it is a serious problem that
has an impact on their life, oral hygiene habits and even their diet.
If
not given the attention needed, sensitive teeth might
develop into other oral problems. This frequently happens when pain
impedes normal toothbrushing, making the affected person more vulnerable
to caries and gum diseases. If you fell uneasy when eating certain
types of food, visit your dentist. Having Sensitive teeth is a very
common problem that affects one in seven people. The teeth
that are most greatly affected by hypersensitivity are canines and
pre-molars, whereas molars are the least affected. People between ages
20 and 40 and women as opposed to men are more likely to be affected.
Under normal conditions, when
teeth are in their natural position, enamel is the only element to be
in contact with the oral environment, and the gum line is situated at
the cemento-enamel junction (Tooth Anatomy).
