FYI: Before the early-1900s almost no one in America brushed their teeth.
It wasn’t until advertising executive Claude Hopkins came along to pitch Pepsodent that this all changed. Hopkins had previously sold people on the idea of Schlitz beer, Palmolive soap, and Goodyear tires. Now he had a friend who wanted him to help get people to use minty paste to brush their teeth.
