A 1-year-old male German Shepherd dog was brought in because its hard palate had been damaged by the left mandibular canine tooth. On inspection of the oral structure, lingual deviation to the interproximal area between the upper canine and lateral incisor of the left mandibular canine tooth and mild palatal trauma were seen. Under radiographic examination no traumatic root lesion or residue from the extracted deciduous teeth was determined. The mandibular canine tooth was corrected using a metal inclined plane. After 2 months the lower canine was tilted labially by sliding it along the slope as the dog closed its mouth.
