Gleem is a brand of toothpaste made by the Procter & Gamble company. Advertisements in the 1950s stated that it has GL-70, a supposed odor- and bacteria-fighting compound. Gleem was introduced in 1952 with advertising coordinated by Compton Advertising, Inc. The League Against Obnoxious TV Commercials included a Gleem toothpaste commercial in its list of the terrible 10 in May 1963.
