Diagram of the Decayed Tooth

Diagram of the Decayed Tooth

bar.GIF (1268 bytes)

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.
