Attrition

There is a normal amount of wear of the tooth surface from normal mastication, the force of tooth against tooth contact of molars, malocclusions of other teeth and chewing the hair coat, this is termed attrition. When the wear is light or gradual, the tooth responds by the odontoblasts producing tertiary dentine to seal and protect the underlying pulp. Tertiary dentine is often observed as a honey brown discolouration of the tooth, is smooth on probing and appears schlerotic and disorganized on radiograph. If the wear is rapid, or if the odontoblasts do not produce adequate tertiary dentine to ensure the pulp remains covered, the pulp canal becomes open and the pulp exposed to the oral environment, leaving it open for infection and subsequent pulpitis.
