Diagram of the Decayed Tooth

The picture displays a cavity in cross-section of an upper and lower "cuspid" tooth. The decay is caused by a demineralization of the hard tooth structure by the dental plaque invading the interior of the tooth. The cavity has not yet penetrated to the pulp (dental nerve). Regular preventive care can detect these carious lesions and a filling can be placed before more damage is done.

Decay has not penetrated the dentino-enamel junction

Decay has penetrated into the dentin and is very close to the dental nerve
