While bacteria and microscopic particles can indeed become prevalent around the base of the teeth, these are not problems that are going to be solved by the pecking of a bird large or small.
Leeches are another matter, and crocodiles certainly suffer from these insidious passengers. It's generally thought that gaping the mouth during the day helps a crocodile to dry its mouth and hence discourage leeches, but do birds also help out?
If they do, it hasn't been documented as such.
So what's going on? Am I just a born skeptic? Perhaps I am, but that doesn't mean there isn't something in this compelling relationship.
