This is an overview, not a prescription or a recommendation for a specific individual animal.

07 · HOME CARE

What can owners do at home?

  • Follow postoperative food, medication and activity instructions.
  • Use only approved dental-care products and techniques.
  • Report drooling, swelling, bleeding or refusal to eat.
08 · WHAT NOT TO DO

Avoid actions that could make care less safe.

  • Do not attempt to scrape teeth, pull a loose tooth or treat an oral infection with leftover antibiotics.
  • Do not give human medications, leftover prescriptions or supplements without veterinary approval.
  • Do not stop, increase, decrease or double prescribed medication without contacting your veterinary team.
  • Do not delay assessment if symptoms are worsening, the animal stops eating or an emergency sign appears.
09 · PROGNOSIS AND PREVENTION

What can the longer-term outlook involve?

Comfort often improves after diseased teeth or infected tissue are appropriately treated; future care depends on the underlying condition and ongoing prevention.

Can risk be reduced?

  • Discuss regular oral assessments, home brushing and professional care when indicated.
10 · WHEN TO CONTACT YOUR VETERINARIAN

When should you arrange care?

  • Call for bad breath, drooling, chewing changes or visible gum inflammation.
