Treatment involves eliminating the trauma to the palate from the canine tooth and closing the oronasal fistula ONF in this dog. This is due to trauma from a base narrow canine tooth. Hair and debris are present within the defect in the palate extending into the nasal cavity causing a chronic nasal discharge.

Following cleaning and debridement of the defect the mandibular canine that was causing the damage was reduced in height and a partial pulpectomy and vital pulp therapy was performed.  Two months were given for tissue healing prior to closing the fistula.
