dentish
The language an individual speaks when a dentist is asking questions while working on his/her teeth. Is usually depicted as continuous gurgling and nonsense, and is quite difficult for non-dental experts to understand.
Dentist: (cleaning teeth) "So, how has school been going lately? Getting good grades, I assume!"
Patient: (speaking dentish) "Gloshfolshlshlsosshshsohgsohslgshoo."
Dentist: "That's wonderful! Hey, could you open up a little wider?"
