Malocclusion in Dogs
Malocclusion is a medium-severity dental condition that can affect dogs of all ages and breeds. Malocclusion is abnormal tooth alignment due to jaw length discrepancy or individual tooth malposition. It ranges from breed-specific normal variation (brachycephalic underbite) to clinically significant abnormalities causing tooth-on-tooth or tooth-on-palate trauma. It is documented across 6 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at Puppyhood. Early signs to watch for include abnormal bite, lower teeth hitting upper palate (causing ulcers), drooling, and difficulty prehending food. When treatment is required, costs are estimated at £400-£1,500 depending on severity, location, and the specific intervention needed. Malocclusion has a hereditary component, so health-screening certificates from the breeder are strongly recommended for predisposed breeds. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
Signs & Symptoms
The following symptoms are commonly associated with Malocclusion in dogs. If your dog displays several of these signs, consult your vet promptly — early diagnosis typically leads to better outcomes.
- Abnormal bite
- Lower teeth hitting upper palate (causing ulcers)
- Drooling
- Difficulty prehending food
- Abnormal facial appearance
Treatment Overview
Minor malocclusions are monitored. Clinically significant cases causing soft tissue trauma require orthodontic treatment (bite plates, crown reduction) or extraction of offending teeth.
Typical onset: Puppyhood
Prevention & Screening
While not all cases of Malocclusion can be prevented, the following steps reduce risk or enable earlier intervention:
- Do not breed dogs with clinically significant inherited malocclusion
- Monitor deciduous dentition and extract retained baby teeth promptly
Estimated Treatment Cost
Treatment for Malocclusion is estimated at £400-£1,500, depending on severity, the specific intervention required, and your location. Costs may be higher for surgical procedures or ongoing management. Comprehensive pet insurance covering hereditary conditions is strongly recommended.
