Fractures of the cheek teeth crowns occurs rarely in horses. While traumatic injury can result in a fracture, usually there is underlying dental disease that contributes to it. Often the fractured tooth has been weakened by infection or abnormal wear from poor occlusion.
Small fractures of the grinding surface may not cause any problem and may simply be monitored. However, deeper fractures may require veterinary attention. They may involve the deeper structures of the tooth (pulp cavities), allowing bacterial infection of the root and result in the death of the tooth.
Often, cracked crowns are “incidental findings” on a careful dental exam. In other cases, they are discovered after a horse shows clinical signs of nasal discharge, head swelling or difficulty eating.
Diagnosis requires a thorough dental exam, with good light and a mirror. Radiographs are often needed. In some cases, advanced imaging like CT is required to fully understand the extent of a fracture and the resulting dental disease.
Treatment depends on severity of crack and the associated disease. Often dental extraction is required.
