In dogs and cats, malocclusion ranges from mild overbites to severe jaw length discrepancies where teeth puncture the palate. Brachycephalic breeds are especially prone due to shortened skulls. In rabbits, guinea pigs, and chinchillas, continuously growing teeth that do not align wear unevenly, creating painful spurs that impede eating. Treatment depends on severity. Dogs and cats may need tooth extraction or orthodontic intervention. Small herbivores require regular dental filing under sedation. Early detection through routine oral exams prevents complications like abscesses and weight loss.
