Trauma to a tooth (mechanical, chemical, thermal, infective) often results in pulpal inflammation (pulpitis). (pic E1)

Depending on the type of trauma, its severity or duration, the pulpitis may be reversible, but often this is not the case and the inflammation becomes irreversible. The result of untreated irreversible pulpitis is pulp necrosis, followed by the spread of inflammation to affect the apical periodontium (apical periodontitis) and the periapical bone, resulting in bone destruction around the apex of the root (periapical disease).

A tooth affected by pulp and periapical diseases should always be treated, it cannot just be ignored. There are two available treatment options, namely to extract the tooth or to perform endodontic treatment and retain the tooth.

Fractures may also be classified as crown only, crown-root fractures or root fracture.

 

Causes of tooth fractures :  

Chewing hard objects should be avoided. Stones, bones and certain toys are harder than the tooth substance and can result in fracture of the tooth. A slab fracture of the carnassial tooth usually results from dogs chewing, whilst trauma to the anterior teeth (canines and incisors) results from catching a hard object for eg. Stones/Frisbees. Trauma to the front teeth can also result from an anterior collision – with a stationary object or another dog. External head trauma from RTAs or external blows/kicks can also result in tooth fractures.
