Good catch -- and honestly my response is going to be to tell you to take that dog in for some bloodwork. Kidney problems can show up in mouth ulcers. A dog can 'hide' symtoms of things and you may not even KNOW they're having a problem until you see a symptom like this.
Generally mouth ulcers are indicative that something's wrong in the stomach -- too much acid or base somehow and that's not typical. I wouldn't wait -- I'd go to the vet like Monday. It might not be anything 'big' but it could be the earliest warning you would get OF something nasty.
