Arm & Hammer Complete Care TV Commercial, 'Dental Students Under the Black Light'

Four dental students are set up in front of mirrors and asked the question: is your toothpaste working? They're shocked when a black light switches on to illuminate all the plaque left behind by a non-baking soda toothpaste. Fortunately, Arm & Hammer promises its Complete Care toothpaste removes up to five times more plaque.
