The causes and treatment of Dental Hypersensitivity


Tooth hypersensitivity is a common dental problem.

It is a sharp dental pain of short duration which arises from various triggers like thermal (hot and cold), evaporative, chemical, osmotic or electrical. It can develop over time, as a result of other problems like receding gums and enamel wear.

People with age between 20 and 50 years are more likely affected by this problem.

What causes tooth sensitivity?

This layer wears off easily with tooth brushing exposing the underlying dentin layer of the tooth.

As dentin layer is traversed by thousand of channels from the outer surface toward the centre, external triggers can stimulate the nerves inside the tooth causing sharp sensation.
