Gingivitis in cats is treatable and, importantly, reversible if caught early. Unlike more advanced periodontal disease, the gum inflammation at this stage hasn’t yet destroyed the deeper tissues anchoring your cat’s teeth. Treatment typically combines a professional dental cleaning under anesthesia with ongoing home care to keep plaque from building back up. The approach depends on how far the inflammation has progressed and whether your cat has a more severe condition called gingivostomatitis.
Why Early Treatment Matters
Gingivitis begins when plaque, a sticky film of bacteria, migrates from the visible tooth surface down toward the gum line and eventually below it. Your cat’s immune system reacts to those bacteria with inflammation, and that’s what you see as red, swollen gums. At this point, the damage is still confined to the soft tissue and can be fully reversed.
If gingivitis goes untreated, it can progress to periodontitis. In periodontitis, both the bacteria and your cat’s own immune response start destroying the deeper structures that hold teeth in place, including bone. That damage is permanent. Teeth loosen and may fall out. Controlling gingivitis before it reaches this stage is the single most important thing you can do for your cat’s oral health.
Professional Dental Cleaning
The foundation of gingivitis treatment is a professional cleaning performed by a veterinarian under general anesthesia. Cats won’t hold still for the kind of thorough cleaning their teeth need, and anesthesia also allows the vet to probe below the gum line and take dental X-rays to check for hidden problems.
During the procedure, the vet removes plaque and tartar from both the visible crown of each tooth and the area beneath the gum line using ultrasonic instruments and hand tools called curettes. The subgingival cleaning, the part below the gums, is actually the most important step because that’s where the bacteria driving the inflammation live. Afterward, the teeth are polished with a fine-grit paste to smooth out tiny scratches left by scaling. Those micro-abrasions would otherwise give plaque an easier surface to cling to.
The cost for a cat dental cleaning typically ranges from $300 to $682, with an average around $375. That usually includes anesthesia, though pre-anesthetic bloodwork, X-rays, and any extractions can push the total higher. If your cat has teeth that are already loose or severely affected, your vet may recommend pulling them during the same procedure. Recovery from extractions generally involves soft food for several days, with a recheck visit scheduled 7 to 14 days later to assess healing.
Home Care After the Cleaning
A professional cleaning resets the clock, but plaque starts re-forming within hours. Without consistent home care, gingivitis will return. Daily tooth brushing is the gold standard for prevention. If daily isn’t realistic, aim for at least every other day, working up to about 30 seconds of brushing on each side of the mouth.
Use a pet-specific toothpaste (human toothpaste contains ingredients toxic to cats) and a small, soft-bristled brush or a finger brush. Most cats need a gradual introduction: start by letting your cat lick the toothpaste, then progress to rubbing a finger along the gums, and finally introduce the brush over a period of days or weeks. Focus on the outer surfaces of the teeth, where plaque accumulates fastest.
Dental Diets and Supplements
If your cat refuses brushing entirely, you still have options. The Veterinary Oral Health Council (VOHC) awards a seal of acceptance to products proven to reduce plaque or tartar. Their approved list for cats includes dental diets, water additives, oral gel sprays, dental treats, and even specialized wipes. These aren’t as effective as brushing, but they provide a meaningful layer of protection for cats who won’t tolerate a toothbrush. You can search the full list of VOHC-accepted products on their website.
When Antibiotics Are Needed
Antibiotics aren’t a standard treatment for simple gingivitis, but your vet may prescribe them if there’s an active infection, significant swelling, or if extractions were performed. One commonly used antibiotic for feline dental infections is given once daily for up to 14 days, depending on severity. Your vet will determine the appropriate medication and duration based on your cat’s specific situation. Antibiotics alone won’t resolve gingivitis because they don’t remove the plaque and tartar driving the inflammation.
Gingivitis vs. Gingivostomatitis
Not all gum inflammation in cats is straightforward gingivitis. Feline chronic gingivostomatitis (FCGS) is a more severe condition in which the immune system overreacts to plaque, causing intense inflammation that spreads beyond the gum line to the tissue in the back of the mouth, under the tongue, and along the inner cheeks. Signs include extreme oral pain, drooling (sometimes with blood in the saliva), refusal to eat even when hungry, weight loss, and pawing at the mouth.
A veterinarian can distinguish gingivostomatitis from simple gingivitis in about 85% of cases just by looking inside the mouth, according to Cornell University’s Feline Health Center. The hallmark difference is location: simple gingivitis stays close to the teeth, while gingivostomatitis produces ulcerated, bleeding lesions across wider areas of the oral cavity, particularly around the premolars and molars and in the back of the throat.
Gingivostomatitis requires more aggressive treatment. Many cats with this condition ultimately need full-mouth or near-full-mouth tooth extractions to remove the surfaces where plaque accumulates. While that sounds dramatic, most cats eat comfortably without teeth, and roughly 60 to 80% of cats improve significantly after extraction. If your cat’s gum inflammation seems disproportionately severe or keeps recurring despite good dental care, ask your vet to evaluate for FCGS.
Keeping Gingivitis From Coming Back
Gingivitis is one of those conditions where ongoing management matters more than the initial treatment. After a professional cleaning, the trajectory of your cat’s oral health depends almost entirely on what happens at home. Cats who receive regular brushing and plaque-control products between cleanings can go much longer before they need another professional procedure. Cats who get no home care may need cleanings annually or even more frequently.
Watch for early warning signs between vet visits: a thin red line along the gum margin, bad breath that worsens over time, reluctance to chew hard food, or subtle changes like eating only on one side of the mouth. Catching a flare-up early means simpler, less expensive treatment and a much better chance of keeping all your cat’s teeth intact long-term.
