Well, this may have been the way to do it in the stone age (atleast
before I started grad school (^8 ). Today there is a field of medical
technology called BioSensors.  There are a whole host of *very* small
devices which could be implanted in the mouth to record pH
*continuously* over a week or so.  Actually, this would be an 
interesting experiment to undertake. I'd be a bit surprised if the same
thing has not already been done (atleast in a bovine or swine model).
