Feline stomatitis is severe mouth inflammation - full mouth tooth extraction costs $1,500-$3,000 and cures 60-80% of cats. An immune overreaction to plaque bacteria causes inflammation of gums, cheeks, and throat. Cats stop eating from constant pain. Medical management alone usually fails.
What Causes Stomatitis
An immune overreaction to dental plaque bacteria causes inflammation beyond typical gingivitis. The immune system treats normal oral bacteria as a threat. Feline calicivirus may play a role. It's immune-mediated, not caused by poor dental hygiene alone.
An immune overreaction to oral bacteria
Symptoms What to Watch For
Severe pain while eating - dropping food, crying when chewing. Thick, blood-tinged drooling. Appetite and weight loss. Bad breath. Pawing at mouth. Unkempt coat. Bright red, swollen gums extending to the back of the throat. Some cats become reclusive from pain.
Severe oral pain is the hallmark
Diagnosis $200-$500
Oral exam under sedation ($100-$200). Full mouth X-rays ($200-$300). Biopsy ($100-$200) rules out cancer. Blood work ($100-$200) checks for FIV and FeLV. Diagnosis is usually evident from the distinctive bright red proliferative inflammation.
Average $200-$500
Treatment $1,500-$3,000 Extraction
Full mouth tooth extraction is most effective - 60-80% of cats improve dramatically or are cured ($1,500-$3,000). Extracts all premolars and molars, sometimes all teeth. Steroids ($20-$50/month), antibiotics, and pain meds usually provide temporary relief only.
Full mouth extraction $1,500-$3,000
Total Cost $2,000-$4,000
Diagnosis + extraction + recovery care. Cats that don't respond to extraction need ongoing medications at $50-$200/month.
Breed Risk Siamese, Abyssinians
Siamese and Abyssinian cats appear predisposed. Persians and Himalayans also at higher risk. Can affect any breed.
Recovery 2-4 Weeks Post-Extraction
Mouth healing takes 2-4 weeks after extraction. Most cats eat better within days - even without teeth. Quality of life improves dramatically.
Prevention
No proven prevention since it's immune-mediated. Regular dental care may help. Keep FIV/FeLV testing current. Early intervention improves outcomes.

Insurance Traps
An expensive dental/immune condition - here's how insurance handles it.
Stomatitis Coverage Basics Exclusion
Some policies cover stomatitis as an illness (immune-mediated), others exclude it under dental exclusions. Full mouth extraction is medically necessary, not elective. Check your policy's dental and illness coverage.
The Dental Pre-Existing Trap Pre-existing
Any documented dental issues, gingivitis, or oral inflammation before enrollment may deny stomatitis claims as pre-existing. Even a routine dental cleaning note mentioning redness can be problematic.
Extraction Surgery Coverage Coverage
Full mouth extraction costs $1,500-$3,000. Some policies require it to be classified as medically necessary, not cosmetic. Get pre-authorization before proceeding to confirm coverage.
Dental Exclusion Policies Exclusion
Many policies exclude dental procedures by default. Stomatitis is an immune disease treated with dental surgery - some cover it, others deny it. Read the dental exclusion carefully and ask about stomatitis coverage before enrolling.
Common Questions
Real answers about costs, treatment, and insurance coverage.
What are the symptoms of stomatitis in cats?
Severe oral pain: cats cry, drop food, or avoid eating. Heavy, blood-tinged drooling, bad breath, weight loss, pawing at mouth, unkempt coat. On exam, gums, cheeks, and throat appear bright red, swollen, sometimes ulcerated. Inflammation extends beyond the gum line.
How much does stomatitis treatment cost for cats?
Diagnosis: $200-$500. Medical management (steroids, antibiotics, pain meds): $50-$200/month, temporary relief only. Full mouth extraction: $1,500-$3,000. Total: $2,000-$4,000. Cats not responding to extraction need ongoing medication.
Why does full mouth extraction help stomatitis?
The immune system overreacts to plaque on tooth surfaces. Removing the teeth removes the trigger. About 60-80% of cats experience dramatic improvement or complete resolution. Cats eat well without teeth - they tear food rather than chew.
Can cats eat without teeth?
Yes - cats eat well without teeth. They tear rather than chew. Most eat both wet and dry food within days to weeks after surgery. Many eat better after extraction because they're no longer in constant pain. Wet food is recommended during healing.
Can stomatitis in cats be cured?
Full mouth extraction cures or dramatically improves 60-80% of cats. The remaining 20-40% need ongoing immunosuppressive medication. Medical management alone rarely provides lasting relief - most cats relapse when steroids are tapered.
Is stomatitis contagious between cats?
Stomatitis itself is not contagious - it's immune-mediated. Feline calicivirus, which may contribute, is contagious. Cats with stomatitis should be tested for FIV and FeLV. Predisposition may have a genetic component in some breeds.
What breeds are prone to stomatitis?
Siamese and Abyssinians appear predisposed. Persians and Himalayans are also commonly affected. Any breed can develop it. FIV/FeLV-positive cats and those in multi-cat environments face higher risk.
Does pet insurance cover stomatitis treatment in cats?
Coverage varies - some cover stomatitis as an illness (immune-mediated), others exclude it under dental exclusions. Extraction coverage depends on classification: medically necessary illness vs. dental procedure. Ask your insurer about stomatitis and extraction coverage before enrolling.
My mother-in-law's boxer. Problem. $1,200 in tests, no answers. Another vet solved it with $8 pills. When you're scared, you'll pay anything - and some vets price accordingly. So I built what I couldn't find: real costs, real exclusions, plain language. Not selling policies.
