Gingivitis is inflammation of the gums that surround a cat’s teeth, and it is one of the most common dental problems in cats over four years old. It starts when plaque, a soft film of bacteria, food debris, and saliva, builds up along the gum line. Within a few days plaque hardens into tartar, and the bacteria underneath irritate the gum tissue. The good news is that gingivitis is the only reversible stage of dental disease: treated early, the gums can return to full health. Ignored, it progresses to periodontitis, which destroys the bone and ligaments that hold teeth in place.
Signs Your Cat May Have Gingivitis
Cats are experts at hiding oral pain, so owners often notice nothing until the disease is advanced. Look for a thin bright red line where the gum meets the tooth, swollen or puffy gums, bad breath that is stronger than normal, drooling, or food dropped around the bowl. Some cats chew on one side, paw at the mouth, prefer soft food, or stop grooming because the mouth is too sore. Advanced cases include bleeding gums, visible tartar, weight loss, and reluctance to eat at all.
When to See a Vet
Book a dental examination if you notice red gums, persistent bad breath, drooling, dropping food, or any drop in appetite that lasts more than a day. Seek urgent care for bleeding from the mouth, refusal to eat, or pawing at the face. Because cats mask pain so well, an annual oral check as part of the routine wellness exam is important even when nothing looks wrong. Definitive diagnosis requires an examination under anesthesia, which lets the vet probe below the gum line and take dental X-rays to see the roots and bone.
Common Vet-Directed Treatments
Treatment begins with a professional dental cleaning under general anesthesia. The veterinarian scales plaque and tartar from above and below the gum line, polishes the enamel, and takes full-mouth radiographs to find hidden problems such as bone loss, tooth resorption, or abscessed roots. Loose or badly diseased teeth are treated or extracted. Severe cases involving feline chronic gingivostomatitis, where the whole mouth is inflamed, may need extraction of affected premolars and molars to make the cat comfortable. Because viruses such as FeLV and FIV, kidney disease, and immune problems can worsen gum inflammation, your vet may also run blood tests and check vaccination status.

Home Care That Protects the Gums
- Brush daily or at least several times a week with a cat-sized toothbrush and enzymatic pet toothpaste. Never use human toothpaste: fluoride and xylitol are toxic to cats.
- Introduce brushing slowly: let your cat lick a dab of toothpaste from your finger first, then touch the canine teeth, then brush the outer surfaces along the gum line for fifteen to thirty seconds.
- Use dental gels, water additives, or VOHC-accepted dental treats as supplements, not replacements for brushing.
- Soft food is easier for a sore mouth during recovery, but return to a tooth-friendly routine once healed.
Prevention
Consistent plaque control is the whole game. Start brushing in kittenhood if possible, keep the routine calm and reward-based, and schedule professional dental checkups as your veterinarian recommends based on your cat’s mouth. Cats that eat normally can still have significant hidden dental disease, so do not rely on appetite alone as a sign of health. A few minutes of home care each week is far kinder, and far cheaper, than major dental surgery later in life.
