A 1.7-year-old indoor domestic shorthair cat with no reported history of trauma was referred because of a missing left maxillary canine tooth. Two weeks prior to presentation, oral examination by the referring veterinarian revealed the presence of a complete set of permanent teeth, except for a persistent deciduous left maxillary canine tooth and absence of the permanent left maxillary canine tooth.
