Tooth neck hypersensitivity may have several underlying conditions, some of the most
common causes:
Hypersensitivity of the tooth neck
Dentin hypersensitivity
Hypersensitivity: painful condition of the teeth surface. More exactly: hypersensitivity of the
dentin.

Dentin hypersensitivity
Intense, shooting pain - what cannot be associated with any other tooth condition - is the
abnormal response of the exposed dentin to thermal, tactile, osmotic, chemical and other
stimuli. (Broken teeth, caries, secondary caries, broken fillings, outgrows may cause similar
symptoms). In most of the cases, affects patients with good oral hygiene. Its prevalence is
high in the age group of 30-60, but occurs above and below these ages. In Hungary 33% the
population 30-60 have sensitive teeth. 2/3 of them regularly, 1/3 of them occasionally suffers from the hypersensitivity.

Conditions predisposing to tooth sensitivity

1. Surface layer The dentin channels can seal themselves in a natural way; plaque building may cover and seal the dentin surface 2. Intratubulary dentin Substances of the saliva penetrate into the dentin channels and produce occlusions through crystal building. Inner occlusions may develop by the sclerotisation of the root dentin. 3. Tertiary dentin Dentin producing cells (odontoblasts) of the dental pulp secrete tertiary dentin when irritated. They are sealing the dentin channels with a collagen like substance. |
