Oh no! I have the fix for stomatitis!
Stomatitis is so about inflammation. Cbd made for cats. It has to be thc-free, and thc is what gives that 'high'. So you don't get a high cat from it.

Cbd is useful to treat many things. Nausea, anxiety & depression, works as an appetite stimulant and is a natural anti-inflammatory. I was using it on my girl with small cell lymphoma gi. To help the inflammation in her gut. Seeing how it helped her, I decided to try it out on my boy with stomatitis. You see, my boy DID have almost all his teeth removed. But that didn't stop the problem. The inflammation was still there. Even with a nearly empty mouth, his gums were the problem. They would still get swollen. You could see it. And then the drool would begin. Sometimes even pink tinged from some blood. And really bad breath.
So! I started giving him 1.5mg of cbd in his food, twice a day. For my kind, that equaled 0.15ml, and it tasted like catnip. So he never noticed it. It took 1-2 weeks to get the full results. He used to have regular flare up at least once a month. But in the 2yrs he was on that? Not a single flare up. It was amazing! I even taught it to my vet and she tells other clients about it now. It was wonderful and he was able to have a normal life after that.
So please don't believe anyone if they tell you the removal of the teeth
Oh my gosh, I had this long thing written out. But whenever I write 'too much', the page glitches and then it froze and erased it.

The short. I had a cat with stomatitis. Getting rid of so the teeth does not not cure it. My boy had almost his entire mouth empty, still got at least 1 flare up every month. It was awful. Swollen gums, bad breath, and the drooling. Sometimes pink tinged from blood. The removal doesn't fix it, because it's not a tooth problem, it's an inflammation problem.
What fixed it was addressing the root cause. I used the cat cbd I had been giving my girl for the inflammation in her gut. In the entire 2yrs of giving it to him, not once did he have another flare up.
And I didn't give much. He only took 1.5mg (which was 0.5 ml for his brand) twice a day mixed in his food.
It really was a miraculous fix for him. Not a 'cure', but taking care of you the underlying cause before it a problem. Hope that helps
