With users as pure as this mother/daughter combo, wouldn’t you trust the marketing claims of Amm-i-dent?
Adding ammonium to tooth-cleaning agents was a marketing craze at the time the above ad appeared. An article in the July 30, 1949, edition of Billboard magazine noted that the potential advertising revenue derived from clients like Amm-i-dent and Colgate made radio network and station executives “virtually froth at the mouth.” Amm-i-dent’s American parent Block Drug (maker of such fine products as Polident) had secured a lucrative sponsorship of The Burns and Allen Show. However, a University of Illinois study into ammonium-enhanced dental products showed that their use only reduced the incidence of tooth decay by 10%. As the thrill of ammonium faded, toothpaste makers soon moved on to other marketing gimmicks like chlorophyll.
Though nobody at 172 John Street is marketing tooth powder any longer, other products are getting polished there—thanks to the john st. advertising firm.
