Introduction
Wear on tooth surfaces that are in contact with one another or an abrasive surface. This usually results from tooth on tooth contact in certain malocclusions, chewing on fibrous chew toys and balls eg. Tennis balls. (picE2)
Signalment
Occasionally dogs with chronic skin allergies will get abrasion on the incisors from constantly chewing fur/hair. (picE3)
Aetiology
Often these conditions result from abnormal excessive behaviour.
Excessive wear will often result in exposure of the pulp cavity. If the wear is gradual, the pulp may respond by laying down more dentine – reparative dentine (also known as tertiary dentine).
Clinical Signs
Diagnosis
Treatment
Prevention
Dogs should be prevented from cage biting, excessive play with textured balls and chewing stones.
