Tooth Anatomy - Advanced Tooth Decay

Demineralisation

AnatomyDecayed.jpgWhen plaque remains on the tooth, bacteria produce acid which dissolves the enamel crystals. This process is called ‘demineralisation’. With time, more enamel is dissolved and the bacteria reach the dentine.

Once this occurs a cavity has now formed.

With time, the bacteria progress deeper until the pulp is infected. This leads to inflammation, pain and eventually an abscess. An abscess occurs when the pulp tissue becomes necrotic (dead) allowing infection to tract to the end of the root.

An abscess can be seen in the mouth as a ‘gumboil’.
