Dental disease and tooth resorption in cats: real veterinary cases
Dental disease is the most under-diagnosed condition in cats. By age 3, most cats have some degree of periodontal disease — but because cats hide pain remarkably well, owners often don't notice until the disease is advanced. Tooth resorption (formerly called FORLs) is unique to cats: the body literally dissolves its own teeth from the root up. It affects an estimated 30-70% of adult cats.
Feline stomatitis — severe, painful inflammation of the mouth — is the extreme end of the spectrum. Affected cats may stop eating entirely, drool heavily, and lose weight. The definitive treatment is full-mouth or near-full-mouth extraction, which sounds radical but is genuinely curative in 60-80% of cases. Dental radiographs under anaesthesia are essential — what's visible above the gum line tells less than half the story.
What vets typically check for
- Oral exam under sedation/anaesthesia — conscious oral exams miss most disease in cats.
- Full-mouth dental radiographs: essential to identify root resorption and retained roots.
- Grade periodontal disease and identify all resorptive lesions.
- Treatment: extraction of affected teeth. Suturing the extraction sites is standard of care.
- Stomatitis cases: partial or full-mouth extraction; if medical management fails, extraction is curative in most cases.
Not a replacement for veterinary care. Use this to walk into the conversation prepared, not to self-diagnose.

- Long-term field safety study evaluating allogeneic, uterine-derived mesenchymal stem cells for refractory feline chronic gingivostomatitis.
Journal of feline medicine and surgery · 2026 · United States
A group of cats with chronic mouth inflammation (refractory feline chronic gingivostomatitis) received a treatment of stem cells derived from the uterus to see if it would help their condition. After the treatment, which involved two doses of stem cells, many cats showed significant improvement in their symptoms over the course of a year. Most notably, 69% of the cats gained we
- Combination Therapeutic Effect of Antibacterial and Antiviral Agents on Feline Chronic Gingivostomatitis Nonbounded to Prior Tooth Extraction Confirmed by Physical Signs and Clinical Biomarkers
Veterinary Sciences · 2026 · CH
A group of cats with chronic gum disease (feline chronic gingivostomatitis) showed significant improvement after being treated with a combination of antibacterial and antiviral medications. The cats, some of which had previously undergone tooth extractions, were given these medications to help reduce symptoms like weight loss, poor appetite, and excessive drooling. After treatm
- Species- and breed-associated heterogeneity in age-related increases in periodontal disease risk among dogs and cats based on Japanese insurance claim data.
Frontiers in veterinary science · 2026 · Japan
A study found that as dogs and cats age, their risk of developing periodontal disease (gum disease) increases, but the rate of increase is different between the two species. In general, dogs show a higher risk than cats, and certain breeds, especially brachycephalic breeds like Exotic, Himalayan, and Persian cats, experience a sharper rise in risk as they get older. This resear
- Odontomas in Cats: A Case Series.
Journal of veterinary dentistry · 2026 · United States
A group of eight cats with dental issues, such as missing teeth and swelling in their mouths, were diagnosed with rare benign tumors called odontomas. These tumors can cause tooth displacement and may appear as lumps in the gums. To confirm the diagnosis, veterinarians used imaging and recommended a biopsy. The cats were treated with surgery to remove the tumors, and both surgi
- Efficacy of therapeutic ultrasound as an adjunct to periodontal therapy in cats with early-stage periodontal disease.
Veterinary journal (London, England : 1997) · 2026
A group of 21 young cats with early-stage gum disease were treated to see if therapeutic ultrasound (TU) could help alongside a common mouthwash (chlorhexidine). After a week of daily treatments, the cats that received TU or the combination of TU and chlorhexidine showed significant improvements in their gum health compared to those that only got the mouthwash. Their gum inflam
- CLINICAL AND EPIDEMIOLOGICAL INVESTIGATION OF FELINE CHRONIC GINGIVOSTOMATITIS AND PERIODONTAL DISEASE IN BLIDA, NORTH OF ALGERIA
Archives of Veterinary Medicine · 2026 · RS
A group of cats in Algeria was found to have high rates of oral diseases, with 16% diagnosed with issues like gingivitis and chronic gingivostomatitis (inflammation of the gums and mouth). Common signs included bad breath, pain while eating, and not wanting to eat. Factors like breed, diet, and lack of dental care at home were linked to these problems. To help prevent these con
Frequently asked questions
- Can my cat eat without teeth?
- Yes — cats don't chew the way dogs or humans do; they use teeth mainly for tearing. Cats with full extractions eat wet food happily and many even manage dry kibble. The vast majority are dramatically more comfortable and gain weight after dental extractions.
- Why are dental X-rays necessary?
- Because 40-70% of feline dental pathology is below the gum line. A tooth that looks fine on the surface can have severe root resorption underneath. Extracting without radiographs risks leaving root fragments that cause ongoing pain and infection.
- Is anaesthesia-free dental cleaning a real option?
- No — not for cats. Cosmetic scaling without anaesthesia removes tartar above the gum line but can't address subgingival disease, can't take X-rays, and causes significant stress. Every veterinary dental organisation worldwide advises against it.
