Fractured jaws result from trauma such as dog fights or being hit by a car.  End-stage periodontal disease in small dogs is also another cause that will surprise the pet owner.  It will appear to be a sudden problem, when in reality periodontal disease has resulted in long term bone loss, which so weakens the lower jaw at the level of the first molar that it breaks.

The goal of treatment for fractured jaws is to maintain alignment, restore function, and eliminate pain.  As with any fractured bone healing takes some time.
