About our teeth 

Print this page

Our teeth are composed of layers. The outer white/cream visible layer is made up of a calcium based mineral (hydroxyapatite) called enamel. Enamel is the hardest substance in the human body and provides the incredible strength necessary for many decades of efficient chewing.

Under the enamel is a softer layer of dentine which is a living tissue containing nerve endings. Dentine can be both sensitive to heat and cold and is more easily abraded than enamel if it becomes exposed.

In the centre of the tooth is the pulp cavity containing nerves and blood vessels necessary for the health of the tooth.
