Temporomandibular joint (TMJ) disease in dogs is a condition affecting the joint that connects the jawbone to the skull. This joint plays a crucial role in the movement of the jaw for chewing, barking, and other functions. TMJ issues can lead to pain, discomfort, and difficulties in eating or opening the mouth.

Causes of TMJ Disease in Dogs:

1. Trauma:

Injuries such as fractures or luxation (dislocated jaw) can lead to TMJ problems. This could be due to accidents, falls, or fights with other animals.

2. Arthritis:

Age-related wear and tear or inflammatory diseases can cause arthritis in the TMJ, leading to pain and reduced mobility.

3. Congenital Abnormalities:

Some dogs may be born with structural issues that affect the TMJ, leading to dysfunction.

4. Tumors:

Growths in or around the TMJ can cause pain and dysfunction.

7 Symptoms of TMJ Disease

Pain when chewing or yawning
Swelling around the jaw or face
Grinding or clicking sounds when moving the jaw
