Malocclusion & Misalignment of Teeth in Cats: Vet Dental Guide 2025 🐱🦷

By Dr. Duncan Houston, BVSc

🔍 What Is Malocclusion?

Malocclusion refers to improper alignment of the teeth and jaws in cats. This includes:

• Classes I–III misalignments: overbites, underbites, edge-to-edge bites.
• Crossbites where upper and lower teeth contact incorrectly.
• Crowded, rotated, or impacted teeth that disrupt chewing or cause lesions.

These problems can lead to broken teeth, gingivitis, discomfort, and trauma to oral tissues.

1. Causes & Predisposing Factors

• 🔹 Genetic/hereditary: Persian, Siamese, Burmese and brachycephalic breeds are predisposed.
• 🔹 Congenital jaw discrepancies: maxilla and mandible length differences.
• 🔹 Trauma: jaw fractures or early tooth trauma can disrupt growth.
• 🔹 Tooth crowding: retained deciduous teeth pushing permanent teeth off course.
• 🔹 Lingual displacement: crowding causes molars/premolars to fold tongue injuries.

2. Clinical Signs & Early Identification

• 🦷 Difficulty biting, chewing, or dropping food.
• Pb of oral pain—pawing at mouth, hypersalivation, bad breath.
• Wear or ulceration on tongue, cheeks, palate.
• Malformed jawline, visible under/overbite.
• "Smiley-mouth" in young kittens—when lower canines sit ahead of upper.

3. Diagnostic Approach

1. 🩺 In-clinic examination under sedation: bite assessment, palpate jaws.
2. 📸 Dental X-rays: full-mouth radiographs to check roots, teeth development.
3. 🔍 Photographic documentation: intraoral photos for orthodontic planning.
4. 🧠 Evaluate for concurrent issues: TMJ dysfunction, periodontal disease.
5. 📋 Classify malocclusion: class I normal, class II overbite, class III underbite.

4. Treatment Approaches

a. Extraction

• ✔ Retained baby teeth that block permanent dentition must be removed.
• ✔ Severely malpositioned permanent teeth causing trauma or infection may require extraction.

b. Orthodontic correction

• 🦾 Elastic chain or spring orthodontics can realign canines in moderate cases.
• 📏 Orthodontic appliances like caps or incline bite plates used in specialized centers.
• 🧠 Available in referral dentistry clinics with board-certified specialists.

c. Restorative care

• Composite sealing of enamel lesions from attrition.
• Pulp therapy or root canal when malocclusion causes fractured teeth.

d. Periodontal therapy

• Root planing and gingival care for teeth with plaque from misalignment.
• Supportive hygiene like brushing and professional cleanings every 6–12 months.

5. Post‑Treatment Care & Prognosis

• Soft food diet for 1–2 weeks after treatment.
• Pain meds: NSAIDs or opioids depending on discomfort.
• Re‑examination and radiographs scheduled at 6–8 weeks post-treatment.
• Most cats regain normal chewing; good long-term prognosis if addressed early.

6. Prevention Strategies

• Remove retained deciduous teeth before 6 months of age.
• Breed responsibly—avoid known malocclusion lines.
• Monitor jaw development in growing kittens, particularly brachycephalic breeds.

8. FAQs

Can kitten bites self-correct?

Some minor cases improve as jaw matures—but persistent malocclusion beyond 6–8 months needs attention.

Is orthodontics painful?

It's generally well tolerated; dental pain relief and monitoring are provided throughout treatment.

Will wear damage worsen over time?

Yes—uneven wear can lead to tooth fractures and pulp exposure if untreated.

Can cats eat normally after treatment?

Most cats resume normal chewing within weeks of orthodontic or extraction treatment.

Conclusion

Malocclusion and misaligned teeth can cause pain, oral trauma, and eating difficulties in cats. Early detection, thorough dental assessment, and tailored treatment—ranging from extraction to orthodontic realignment—preserve comfort and function.
