What Causes Sensitive Teeth?

Usually tooth sensitivity (dentin hypersensitivity) presents as temporary tooth discomfort or pain after eating cold food, drinking cold liquids, or breathing cold air. (If the pain is very high in intensity and prolonged, see your dentist because this may be a sign of an unhealthy tooth nerve)

Most commonly, the problem begins when the gums recede. Like a protective blanket, the gums cover the roots of teeth (see diagram below). As gums recede, the underlying tooth roots are exposed.

Gums commonly recede for reasons:

Improper heavy handed brushing of the teeth. It is estimated that 50-90% of people brush with too much pressure. Over weeks, months and years of brushing they remove significant gum tissue exposing the tooth roots.

Poor oral hygiene can lead to plaque build-up around teeth and gums. Over time this plaque hardens into tartar.

Bacteria in this tartar are responsible for the gingivitis and periodontal disease that cause gum recession

Desensitizing Treatment

This treatment can be carried out by in office applications of special coats and Special desensitizing pastes. Sometimes filling is needed if the tooth is having cavity.
