A Tooth Is A Whole Universe

From outside the tooth is covered with the hardest substance in human body – a transparent and shiny covering – the tooth enamel.

Below it there is a tooth tissue called dentine. Dentine consists of tiny canals called dentine tubulae. Inside of the canals there are thin processes, very similar to nerve fibers. It is because of them that this tooth tissue has a high sensitivity. They reach the border with the enamel tissue and because if this fact the dento-enamel junction is very sensitive.

Underneath the dentine layer there is the pulp chamber with the dental pulp inside. Is consists of nerves, blood vessels and cells with different potential of reparation when there are external irritants. When there is an inflammation of the dental pulp (pulpitis) the patient suffers from strong pain (typically during the night) because of insusceptibility of the hard surrounding tissues.

The roots of the teeth are covered with a tissue called cementum. It is considerably less resistant in comparison to enamel. That is why when there is a gum recession (exposing of the tooth’s root) the tooth is already very much more vulnerable to the activity of microorganisms and the acids as a product of their metabolism and it takes less time for a caries to develop.
