Many pet owners are surprised to find out that their pet needs dental care. Imagine though if we never brushed or flossed our teeth, and never went to the dentist! In fact, periodontal disease is the most common infection we see in our pets, affecting 85% of dogs and cats over the age of three years. Periodontal disease is the gradual loss over time of the supporting structures of the teeth. It starts with the formation of plaque which turns quickly to tartar on the tooth surface, and more importantly under the gum line. Left to progress, the gum, bone and other structures surrounding the tooth recede eventually resulting in the loss of the affected teeth. Fortunately, there are things that can be done both at home and in the hospital to prevent the progression of this disease.
