Overview

Advanced gum disease can destroy the tissue and bone around upper teeth until an abnormal passage opens into a neighboring nasal space. A passage into the nose is called an oronasal fistula; one into a nearby sinus space is called an oroantral fistula. The opening can keep the nose inflamed, causing sneezing and nasal discharge even though the underlying problem is dental.

Signs to watch for

  • Repeated sneezing
  • Discharge from one or both nostrils
  • Blood coming from the nose
  • Signs of mouth or facial pain

Can occur in older dogs with established periodontal disease.

When to get help Arrange prompt veterinary assessment for repeated sneezing with nasal discharge or mouth pain.

Diagnosis and tests

The vet examines the mouth under anesthesia, measures pockets around the teeth and takes dental X-rays. These checks can reveal a passage beside an upper tooth and show how much supporting bone has been lost. A CT scan may also help assess the connection and disease inside the nose.
