Key Facts

• Types: overbite, underbite, anterior/posterior crossbite, wry bite, base-narrow canines, open bite
• Overbite (parrot mouth): lower jaw shorter than upper; genetic in all breeds
• Underbite: normal in some short-muzzled breeds (Boxers, Bulldogs); abnormal in medium-muzzled breeds
• Retained deciduous teeth are a major cause of acquired malocclusion
• Crowded, rotated, or tilted teeth cause early infection, soft tissue damage, and abnormal wear
• Orthodontic treatment uses brackets, retainers, and elastics; accomplished in months (not years)
• Orthodontic care is for pain relief, not cosmetics; treated pets should not be bred
• Interceptive orthodontics (removing baby teeth by 10 weeks) corrects 50% of minor jaw problems
• Species: dogs and cats
