Jaw Fractures

Jaw fractures can happen in both the upper and lower jaws and may involve one side or both. Some are easy to spot, showing up as visible swelling of the face or difficulty eating, while others can be harder to detect without imaging.

Most Common Causes

Car accidents

Trauma from fights with other animals

Complications following a tooth extraction

Less commonly, oral cysts, tumors, or metabolic disease

Advanced periodontal disease, especially in smaller dogs

Lower Jaw Fractures & How They Are Diagnosed

Lower jaw (mandibular) fractures are among the most common types of oral injuries in pets. These fractures may involve critical structures such as the temporomandibular joint (TMJ) or the mandibular symphysis—the point where the two halves of the lower jaw meet. Injuries in these areas can make it painful or even impossible for your pet to eat, chew, play, or close their mouth comfortably.

Because many jaw fractures aren’t visible externally, accurate diagnosis requires advanced imaging. At East Tennessee Veterinary Dentistry, we use intraoral digital dental radiography as our primary diagnostic method to pinpoint the exact location and severity of the fracture. In more complex cases, we may also recommend computed tomography (CT) to provide a detailed, 3D view of the jaw and surrounding structures. This allows us to plan the most effective treatment for a safe and successful recovery.

Treating Jaw Fractures

Jaw fractures vary in severity and location, and each case requires a tailored approach. Our treatment goals are to:

Restore pain-free function of the jaw
Preserve proper occlusion (how the teeth align)
Ensure your pet can eat and use their mouth normally
Inability to close the mouth

If a fracture heals incorrectly, the teeth may no longer line up, causing chronic pain and long-term oral issues. That’s why proper treatment from a veterinary dentist skilled in oral surgery is essential.

The Bottom Line

Jaw fractures are painful but treatable. With advanced imaging and expert care, we can restore comfort, preserve function, and help your pet heal. At East Tennessee Veterinary Dentistry, our focus is always on returning your pet to a happy, pain-free life as quickly and safely as possible.
