• Dental disease is a common illness in cats.cat image by Dwight Davis from Fotolia.com
  
  Holly Nash, DVM, MS, reports on PetEducation.com that dental disease is one of the most severe medical problems seen in cats. Cats are prone to three different dental diseases: plaque, a build-up of food and bacteria along the gum line; tartar, the result of plaque mixed with saliva causing gingivitis; and periodontal disease, a separation of the gums from the teeth, increasing bacterial growth and causing serious illness. Fortunately, regular teeth cleaning along with a special dental diet help keep the cat's teeth in optimal health.
