No animal lover wants to see their pet in pain. That’s exactly what happens, though, when dogs and cats do not receive adequate dental care. By age three, more than 80% of pets suffer from some form of periodontal disease, and when left untreated, the consequences can be devastating. In addition to causing pain and discomfort, periodontal disease can allow bacteria to enter the bloodstream and travel to the heart, lungs, and kidneys. This can cause organ damage and make your pet quite sick. In some instances, infections that spread from the mouth to other parts of the body can even be fatal.
