Tooth decay and sensitive teeth

A major cause of sensitive teeth is tooth decay. Tooth decay develops as a result of the build up of plaque and tartar on your teeth which then attacks the enamel. This gradually wears down the enamel causing a small hole to develop in this surface known as a cavity.

If this is left unchecked the decay continues into the middle layer or dentin where it is able to quickly access the pulp. The pulp contains nerves and blood vessels which are extremely sensitive and cause pain when exposed to bacteria. This pain is what we know as toothache.

Sensitive teeth are one aspect of tooth decay. So, if you experience a short, stabbing pain as you consume hot or cold drinks then this may be an indicator of tooth decay.

So, it is a good idea to visit your dentist for a check up if you do.
