Dental disease in cats encompasses several distinct conditions, each requiring different approaches to treatment. Understanding these conditions helps you communicate effectively with your veterinarian and make informed decisions about your cat's dental care.

Periodontal disease is the most common dental condition in cats. It begins with plaque (a sticky film of bacteria) accumulating on the teeth. If not removed, plaque hardens into tartar (calculus), which pushes below the gumline and triggers inflammation (gingivitis). Over time, this inflammation destroys the structures supporting the teeth, including the gums, periodontal ligament, and jawbone. Eventually, affected teeth become loose and painful.

Tooth resorption (formerly called feline odontoclastic resorptive lesions or FORLs) affects an estimated 30-70% of cats. In this condition, the cat's own body breaks down and absorbs the tooth structure, starting at or below the gumline. The cause is unknown. Resorptive lesions are extremely painful, and affected teeth typically need to be extracted.

Stomatitis (feline chronic gingivostomatitis) is a severe, debilitating inflammatory condition affecting the gums and mouth lining. Unlike simple gingivitis, stomatitis causes intense, widespread inflammation that often extends to the back of the mouth (caudal mucositis). Affected cats may have difficulty eating, drool excessively, and lose significant weight. The immune system appears to play a central role, and the condition is often associated with chronic viral infections like FeLV or FIV.

Other dental issues in cats include broken teeth from trauma, oral cancers (particularly squamous cell carcinoma), and jaw fractures related to advanced bone loss from periodontal disease.

Cats are notorious for hiding pain, and dental pain is no exception. Many cats with significant dental disease continue to eat, sometimes swallowing food whole rather than chewing. This makes it critically important for owners to know the subtler signs of oral discomfort.

Signs of dental disease in cats include:

• Bad breath (halitosis): While not all bad breath indicates dental disease, a persistently foul odor is one of the most common signs of periodontal problems.
• Difficulty eating: Dropping food, chewing on one side, preferring wet food over dry, or taking longer to eat than usual.
• Drooling: Excessive saliva, sometimes blood-tinged, can indicate mouth pain or inflammation.
• Pawing at the mouth or face: Your cat may rub their face against surfaces or paw at their mouth when experiencing oral pain.
• Red, swollen, or bleeding gums: Healthy gums should be pink. Red, puffy, or bleeding gums indicate inflammation.
• Visible tartar: Yellow or brown buildup on the teeth, especially along the gumline.
• Decreased appetite or weight loss: Mouth pain can make eating so uncomfortable that cats eat less, leading to gradual weight loss.
• Behavioral changes: Irritability, reluctance to be touched on the head or face, decreased grooming, or general lethargy.

If you notice any of these signs, schedule a veterinary dental examination. A thorough oral assessment often requires sedation or anesthesia because cats do not willingly allow detailed examination of their back teeth and gum tissue. Dental X-rays taken under anesthesia are essential for evaluating tooth roots and jawbone, where much of the disease process occurs below the visible surface.

Professional veterinary dental care is the standard of treatment for established dental disease. Unlike cosmetic teeth cleaning in humans, veterinary dentistry requires general anesthesia to perform a thorough cleaning, examination, and any necessary extractions.

What to expect during a dental procedure:

• Pre-anesthetic bloodwork: Your vet will run blood tests to ensure your cat is healthy enough for anesthesia. This is especially important for older cats or those with known health conditions.
• Anesthesia: Modern veterinary anesthesia is very safe, with continuous monitoring of heart rate, blood pressure, oxygen levels, and body temperature throughout the procedure.
• Scaling and polishing: Tartar is removed from all tooth surfaces, both above and below the gumline, using ultrasonic scaling equipment. Teeth are then polished to create a smooth surface that resists plaque accumulation.
• Dental X-rays: Full-mouth radiographs reveal problems hidden below the gumline, including tooth resorption, bone loss, and root abscesses.
• Extractions: Teeth that are severely diseased, resorbing, or causing pain are surgically removed. While the idea of extraction can be unsettling, cats function remarkably well without some or even all of their teeth. Many owners report that their cats seem happier and more energetic after painful teeth are removed.

For stomatitis, treatment often involves extraction of most or all teeth (full-mouth or near-full-mouth extraction). While this sounds extreme, it is the most effective treatment for this condition, with approximately 60-80% of cats showing significant improvement or complete resolution of inflammation after extraction. Cats who respond well to extraction eat comfortably, gain weight, and show a dramatic improvement in quality of life.

Preventing dental disease is far easier, less costly, and less stressful than treating it once it has developed. While not all dental conditions can be prevented (tooth resorption, for instance, has no known prevention), reducing plaque accumulation through home care can significantly lower the risk and severity of periodontal disease.

Home dental care strategies:

• Tooth brushing: Daily brushing with a cat-specific toothpaste is the gold standard of home dental care. Use a soft-bristled toothbrush or finger brush designed for cats. Never use human toothpaste, which contains ingredients toxic to cats. Start gradually, allowing your cat to get used to having their mouth handled before introducing the brush.
• Dental treats and diets: Products with the Veterinary Oral Health Council (VOHC) seal have been proven to reduce plaque or tartar. These include specific dental treats, chews, and prescription dental diets like Hill's t/d.
• Water additives: Some enzymatic water additives can help reduce bacterial growth in the mouth. These are easy to use, though less effective than brushing.
• Regular veterinary dental exams: Your vet should examine your cat's mouth at every checkup. Professional cleanings should be performed as recommended, typically every one to two years, though cats prone to dental disease may need more frequent care.

Starting dental care early in your cat's life establishes good habits and catches problems before they become serious. Even if your cat resists brushing, any effort toward dental hygiene is better than none. Talk to your vet about which combination of prevention strategies will work best for your cat and your lifestyle.
