Feline stomatitis treatment is one of the few places in veterinary medicine where the recommended cure sounds worse than the disease — until you understand what the disease does. Stomatitis is a severe, immune-driven inflammation of the mouth in which the cat's own immune system attacks the tissue around its teeth. Affected cats are in serious pain: they stop eating, drool, paw at their faces and lose weight. The treatment with the best evidence behind it is removing the teeth. Here's what that costs in Canada, and why the insurance question turns on a single word in your policy.
What it costs in Canada
| Scenario | Typical cost (CAD) |
|---|---|
| Initial exam and oral assessment | ~$80–$180 |
| Full-mouth dental radiographs | ~$150–$400 |
| Pre-anaesthetic bloodwork | ~$80–$250 |
| Partial extraction (behind the canines) | ~$1,500–$2,500 |
| Full-mouth extraction | ~$2,500–$4,000 |
| Canadian owner case example | ~$3,200 + tax |
| Post-op pain medication and rechecks | ~$150–$350 |
| Ongoing medical management (steroids/analgesia) | ~$30–$120/month, indefinitely |
These are estimates for general guidance, not quotes. The main cost drivers are how many teeth come out, whether a dental specialist or a general practitioner does the surgery, and the length of anesthesia — a full-mouth extraction is a long procedure, often two hours or more, and anesthesia time is billed accordingly. Full-mouth dental radiographs are not optional here; retained root fragments are a known cause of the surgery failing. See How we estimated these costs.
With insurance vs paying out of pocket
| Scenario | You pay | Insurer pays |
|---|---|---|
| No insurance | Full $1,500–$4,000 | $0 |
| Policy covering dental illness | Deductible + co-insurance | Usually covers — this is the wording that matters |
| Policy covering dental accidents only | Full cost | $0 — stomatitis is a disease, not an injury |
| Dental disease documented before enrolment | Full cost | $0 — pre-existing, and dental notes are always in the record |
Why removing the teeth is the treatment
Stomatitis isn't an infection you can clear with antibiotics. The prevailing understanding is that the cat's immune system mounts a disproportionate response to plaque bacteria on the tooth surface — so as long as the teeth are there, the trigger is there. Removing them removes the trigger.
The results are better than the procedure sounds. A substantial majority of cats improve significantly after extraction, and a meaningful proportion are considered cured. That's a far better outcome than long-term steroids, which suppress the inflammation without addressing the cause and bring their own consequences over years of use — including a raised risk of feline diabetes.
Do they really take every tooth?
Not always. Many surgeons begin with partial extraction — removing everything behind the canines, which is where the inflammation is usually worst — and reserve full-mouth extraction for cats that don't respond. Some cats need the second surgery, which is why it's worth asking your vet upfront how they decide, and what a staged approach would cost in total versus doing it all at once.
What life is like for a cat with no teeth
This is the question every owner asks, and the honest answer surprises people: most cats do very well. Cats don't chew their food the way we do — they tear and swallow. Toothless cats routinely eat dry kibble, and the ones that don't manage perfectly well on wet food. What they gain is the absence of constant oral pain, and owners commonly describe a cat that becomes visibly happier, starts grooming again and puts weight back on within weeks.
The one word that decides your claim
Canadian policies split sharply on dental. Many cover dental accidents only — a tooth broken by trauma. Stomatitis is not an accident; it's an illness, so those policies pay nothing. Policies that cover dental illness generally do pay for extraction when it's medically necessary, which stomatitis unambiguously is. That difference is worth several thousand dollars on this one condition, and it's usually in the wording rather than the marketing. Our guide to dental coverage in Canada goes through the specific policy language.
Two common conditions to watch for even on dental-illness policies: a requirement that the cat had a documented dental exam or cleaning within the past 12 months, and exclusion of anything already noted in the record before enrolment. Gingivitis flagged at a routine check-up two years ago can be enough to make later stomatitis pre-existing.
Which cats get it
Stomatitis can affect any cat, but it's seen more often in cats that are FIV or FeLV positive, and it's common enough in young adult cats that age is no protection. Because it's immune-mediated rather than a hygiene failure, brushing your cat's teeth diligently will not prevent it — a point worth making, because owners often carry unwarranted guilt about this diagnosis.
Signs it's time to see a vet
Drooling — sometimes blood-tinged — dropping food, approaching the bowl and backing away, pawing at the mouth, a sudden shift from dry to wet food, weight loss, and stopping grooming. A cat in oral pain hides it well until it can't, so a cat that has quietly become scruffy is worth an oral exam.

Considering insurance?
Stomatitis is the condition that separates policies covering dental illness from those covering dental accidents only — a difference worth thousands on this diagnosis alone. Compare Canadian plans.
