It does look like an oral papilloma. If you google it, a lot of images come up that look just like this, including the grey color.
But when it comes to growths of any kind, guesses are not useful. I'm glad she is taking him to the vet.
The coloring definitely threw me off. Oliver's was more round, pink and cabbagy looking. Thanks for the opinion and have a good night :)
