Malocclusion is an abnormality in the position of the teeth. It is common in the dog but is also seen in cats. The clinical significance of a malocclusion is that it may cause discomfort and sometimes pain to the affected animal. In some cases, it may be the direct cause of severe oral pathology. It is consequently important to diagnose a malocclusion early in the life of the animal so that preventative measures can be taken.

Established malocclusion can be treated in several ways, i.e. extraction, tooth shortening and endodontic therapy or in selected cases, by orthodontic movement of teeth.

Orthodontics is not indicated for a malocclusion of genetic origin.
