The act of uber teeth brushing/cleaning/flossing just before going to the dentist, to make sure you don't appear filthy to the dentist; similar to cramming before an exam, but with dental hygine; born from a deep seated need to impress with obscene cleanliness.
I have to get up half an hour early to leave time for a good dentocram before my dentist appointment tomorrow.

Can't go to the dentist unless you dentocram, doesn't feel right...
