Teeth, Tootsie Rolls, Cavities, Teeth Whitening, Gum Disease - what do they have in common?
That question has been asked, (by the makers of Tootsie Rolls), and answered over 20,000 times by kids of all ages since 1970. The guesses ranged from between 100 - 5,000 licks, with the average answer being 700 licks. A "licking machine" was created by Purdue University, in an attempt at a scientific answer. A control group of humans licked an average of 252 licks, and the machine's average was 364.
