Gingivitis is the most common type of oral disease among cats. It's as prevalent among cats as it is in dogs or humans. However, cat gingivitis may involve more than the simple swelling and bleeding of the gums you might experience in your own mouth. Indeed, in some cases, it can be life-threatening.
Because it's so common — as well as potentially complex and severe — it's important for cat parents to understand the causes and signs of feline gingivitis, as well as basic treatment and prevention measures.
Gingivitis is a swelling of the gums. It mostly occurs in senior cats, when plaque builds up and the gums respond with swelling, redness, bleeding and sensitivity. Plaque is an accumulation of bacteria combined with substances that turn the mix into a concretion that adheres to the teeth. Plaque leads to swelling of both the gums and the periodontal ligament — the structure that attaches teeth to the underlying bone.
When the periodontal ligament reacts to plaque with swelling and deterioration, the resulting disorder is referred to as periodontitis, or periodontal disease. When the gums react, the result is gingivitis. These diseases are often incorrectly used interchangeably, so it's important to distinguish them from one another.
In most cats, gingivitis is the result of gradual plaque accumulation, a process that occurs as cats age. There's tremendous variation in the degree to which cats' gums react to plaque. Some cats seem to accumulate large amounts of plaque with a minimum of gingivitis while other cats' gums react more severely.
A cat's unique degree of gingivitis largely has to do with genetics, but gingivitis in cats can also be affected by certain conditions, including:
The primary signs of feline gingivitis include redness and bleeding at the gumline. More severely affected cats will have oral pain. You'll be able to tell whether your cat is in pain if they do any of the following:
Some severely affected cats will display only very subtle signs of pain. Make frequent health checks and dental cleanings to ensure your cat's mouth and teeth get thoroughly examined on a regular basis.
Addressing plaque is the main goal of gingivitis treatment. Routine dental cleaning under anesthesia can usually take care of plaque buildup. Annual dental cleanings are strongly recommended, with some cats requiring more frequent cleanings. Veterinary dentists, those with additional specialized education in animal dentistry that may perform more complex oral examinations or surgeries from your general veterinarian, don't recommend anesthesia-free dentistry. For more severe cases, veterinarians employ or recommend the following measures:
While once thought to be promising, laser therapy has not yet been shown to be effective.
Plaque control is by far the most effective means of preventing gingivitis in most cats, with daily teeth brushing being the best method. Water additives, chlorhexidine rinses and plaque-control treats are of lower value but can be somewhat effective.
Contrary to common belief, research has yet to show that cat gingivitis can be prevented simply by feeding a cat dry food. When paired with regular dental cleanings, however, specially formulated dental cat foods have been shown to be effective at reducing plaque accumulation and reducing gingivitis. Be sure to ask your veterinarian for foods that are VOHC (Veterinary Oral Health Council) approved — foods that have been shown to reduce tartar and plaque in cats. Cats with more advanced gingivitis tend to ingest and digest moist food better than dry food.
Feeding your cat nutritionally complete and balanced meals is required to help maintain their overall oral health. Coupled with routine dental care, regular veterinary visits and daily brushing, most cats' gingivitis can be successfully managed.
