Gingivitis in Cats
Gingivitis is considered the earliest stage of periodontal disease. This stage is reversible with proper care. It is indicated by inflammation of the gingiva, or gums. In the early phases of gingivitis, some plaque is present and there is a mild redness of the gums, but the gingival surfaces are smooth.
Dental calculus is calcium phosphate and carbonate mixed with organic matter. In advanced gingivitis there are plaque and calculus under the gums, moderate-to-severe redness of the gums and the gum surfaces are irregular. Plaque is the result of a collection of food, debris, bacteria, dead skin cells and mucous. It forms within 24 hours on clean tooth surfaces. The gum responds to plaque with inflammation of the gingival blood vessels, swelling of the gums, and collagen loss from the gums.
The gingival sulcus, or gum pocket, is the narrow space between the inner wall of the gum and the tooth. As gingivitis develops, the bacteria present in these pockets changes, releasing toxins which destroy the gingival tissue.
More than 80 percent of pets three years or older develop some form of gingivitis.
Symptoms and Types
- Red or swollen gums, especially on the side of the gum facing the inner cheeks
- Halitosis/bad breath
- Variable amounts of plaque and calculus on the tooth surface
Plaque Accumulation is one of the main causes leading to gingivitis in both cats and dogs. Predisposing factors include:
- Old age
- Crowded teeth
- Soft food
- Open-mouth breathing
- Bad chewing habits
- Lack of oral health care
- Uremia and diabetes mellitus
- Automimmune diseases
- FeLV (Feline Leukemia)
- FIV (Feline Immunodeficiency Virus)
Your veterinarian will perform a thorough physical exam on your cat, taking into account the background history of symptoms and possible conditions that might have led to this condition. You will need to give a thorough history of your cat's health and onset of symptoms, such as when the bad breath began, what your cat typically eats, whether your cat has had trouble eating/chewing, and whether your cat has had any previous health conditions. The routine you have been using to keep your cat's teeth clean, if you have been using one, should be shared with your veterinarian as well, including the products you use.
Part of the physical exam involves closely examining your cat's mouth to identify the condition. Your veterinarian will then make an appointment with you to bring your cat in for a dental exam. During the dental exam, your cat will be anesthetized. Your veterinarian will check the depth of the gum pockets, the amount of plaque and bacteria on the surface of the teeth, and will pull any teeth that are rotten or that are too crowded. All of the plaque and calculus will be removed using a scaling process that is done with special dental equipment, and if necessary, root planning. The tooth surfaces will be polished and the teeth will be reexamined after cleaning.
