The visual of dental floss forming a brain shape is unexpected and intriguing.

The ad opens with a close-up of a white G.U.M. dental floss dispenser against a bright green background. The text 'G.U.M does more than you think.' appears on screen. The dispenser then releases a long strand of dental floss which begins to form the shape of a human brain. The camera pulls back to reveal the full brain shape made of floss, connected to the dispenser. The ad then transitions to show various G.U.M. dental care products, including floss and picks, arranged on the green background. The pacing is quick and dynamic, with smooth transitions.
