Dental Feature: Extraction

Breed: Havanese cross

Condition:
Endodontic infection and bone weakening

Too often, dental issues are misdiagnosed or left untreated because there is not an obvious tooth fracture. This eight-year-old dog had been experiencing facial swelling and abscesses for two years and was seen by multiple veterinary specialists to try to identify the cause. He had undergone extensive testing, been given numerous rounds of antibiotics and even had two extensive surgeries to see if a foreign body was present.

A new veterinarian diagnosed the patient with infected teeth and referred him to a dental specialist. A basic oral assessment revealed the patient had four draining tracts that had been present for years and many intrinsically stained teeth.

The patient was placed under general anesthesia so a full mouth exam and dental radiographs could be performed. X-rays revealed several infected teeth, noted by the red arrows below.

Radiographs also showed bone weakening in the mandibular left M1 tooth, which predisposed the patient to a pathologic fracture.

Treatment involved extracting the left maxillary third and fourth premolars, mandibular first incisors, left mandibular second and fourth premolars and first through third molars as well as the right mandibular third and fourth premolars and first through third molars. Additionally, all four canines were treated with root canals.

The procedure was a success and resulted in complete remission of the infection. The patient is no longer experiencing facial swelling and is now far more active and happier than he has been in years.
