Tartar is common in older dogs and cats when plaque, a coating of food debris and bacteria, hardens. Animals that eat canned food and lack chew bones are at greater risk. Small dogs are more commonly affected. Tartar can lead to gingivitis, tooth loss and pain. If the infection spreads, it can affect the jawbone, nasal cavity and internal organs via the blood such as the heart and liver.
