Dental & Oral Conditions in Dogs & Cats
The mouth, teeth, and jaw are structurally complex and notoriously difficult to evaluate with standard dental X-rays alone. When pets present with facial swelling, drooling, difficulty eating, or a visible oral mass, understanding the full extent of the problem requires imaging that can see beyond the surface.
At Sage Veterinary Imaging (SVI), our 128-slice CT scanner produces detailed cross-sectional and 3D images of the teeth, jaw bones, hard palate, and surrounding soft tissues — revealing tooth root pathology, bone invasion by oral tumors, jaw fractures, and oronasal communications that dental radiographs and standard X-rays cannot fully characterize.
SVI offers advanced CT imaging at our centers in Round Rock, Texas; Spring, Texas; and Sandy, Utah.
Common Dental & Oral Problems We Diagnose
Dental and oral diseases in dogs and cats range from common tooth root infections to aggressive oral cancers. In all cases, knowing the full extent of disease is essential for treatment planning. CT provides the three-dimensional bone and soft-tissue detail that makes this possible.
Tooth Root Abscesses
Tooth root abscesses are a common cause of facial swelling, particularly involving the upper carnassial teeth (premolar 4) in dogs. While dental X-rays show the tooth itself, CT reveals the full extent of infection — including bone loss around the root, sinus involvement, and whether the infection has eroded through the bone to create a draining tract. This comprehensive view helps veterinary dentists determine whether extraction alone will resolve the problem or whether additional surgical debridement is needed.

Oral tumors are among the most common cancers in dogs, and early, accurate assessment of tumor extent is critical for treatment success. CT reveals how deeply an oral mass has invaded the jaw bone, whether it crosses the midline, and its relationship to the nasal cavity, orbit, and other vital structures. This information determines whether surgical resection is feasible, guides the surgical margins, and helps plan radiation therapy when indicated. CT staging of the regional lymph nodes and chest can be performed in the same session.

Jaw fractures in dogs and cats can result from trauma, dental disease, or weakening by tumors (pathologic fractures). The mandible and maxilla have complex curved anatomy that is poorly represented on standard X-rays. CT shows fracture configuration in three dimensions, identifies tooth root involvement, evaluates the temporomandibular joint (TMJ), and helps surgeons plan fixation approaches. For pathologic fractures, CT reveals the underlying cause and remaining bone stock available for repair.

While routine dental X-rays are standard for evaluating periodontal disease, advanced cases — particularly those involving extensive bone loss, root resorption in multirooted teeth, or suspected palatal erosion — benefit from the three-dimensional perspective CT provides. CT is especially valuable when dental radiographs suggest complex pathology but don’t show the full picture, or when treatment planning requires understanding the relationship between diseased teeth and the nasal cavity or maxillary recess.

An oronasal fistula is an abnormal communication between the oral and nasal cavities, most commonly resulting from extraction of upper canine teeth with significant periodontal bone loss. Pets with oronasal fistulas may sneeze after eating or have chronic nasal discharge. CT maps the exact size and location of the defect, evaluates the remaining bone and soft tissue available for surgical closure, and identifies any concurrent nasal disease that may complicate repair.

Dental and oral conditions affect all breeds, but certain breeds face higher risk for specific problems. Small breeds like Dachshunds, Yorkshire Terriers, and Chihuahuas are prone to advanced periodontal disease and jaw fractures from weakened bone. Golden Retrievers, German Shepherds, and Cocker Spaniels have higher rates of oral melanoma and squamous cell carcinoma. Boxers are predisposed to gingival tumors. Brachycephalic breeds like Pugs and Bulldogs have crowded dentition that increases risk of tooth root pathology.
How CT Imaging Helps
CT is increasingly recognized as the standard of care for complex dental and oral pathology because it shows the teeth, jaw bones, and surrounding soft tissues in three dimensions with sub-millimeter resolution. Where dental X-rays provide a flat, two-dimensional view that superimposes structures, CT separates each layer and allows radiologists to evaluate bone involvement, tumor extent, and anatomical relationships with precision.
Each study is reviewed by our board-certified veterinary radiologists, who provide a detailed report with measurements and 3D reconstructions to help your veterinarian or dental specialist plan the most effective approach.
What to Expect During Your Visit
Dental and oral CT scans are quick — the actual scan takes less than 5 minutes. Your pet will be under brief general anesthesia, which also allows for comfortable, precise positioning. Contrast-enhanced images may be obtained if an oral mass is being evaluated. The entire visit typically takes about an hour.
Results are interpreted by a board-certified veterinary radiologist, and your veterinarian typically receives a detailed report with reconstructions the same day.
