Dogs and cats can sometimes have severe inflammation of the mouth and gingivitis. It is not always known what is the exact cause of this very frustrating condition, but it can be successfully managed. In cases of severe inflammation, some or all of the teeth may need to be surgically extracted. This often greatly improves the pain and inflammation in the mouth. Laser therapy is also frequently used to treat this inflammation. The laser can help destroy abnormal inflamed tissue and allow normal tissue to return in its place. The laser treatments can be repeated as necessary to keep the inflammation under control.
