Can you get an wart in your mouth that is not hpv?

Probably not: The current belief is that warts are caused by one of the many, many strains of HPV. That means a bump on a surface can be from a non-viral cause, but we would call it something else instead of a wart. One's primary care doctor can light up and magnify a bump to see what it might be. Maybe it's a wart, maybe it's something else. An in-person exam is needed because video isn't always clear enough.
