Founded in Chicago in 1926, Dr. West's set modern toothbrush standards with the Miracle-Tuft-early nylon bristles and a surgically sterile glass-tube pack. In 1929 it launched a laboratory-verified toothpaste featuring gentle dual-polishing, quickly winning consumer trust. Through the 1930s–40s the brand led the market (70% sales lead in 1937), advanced public oral-hygiene during wartime, and kept innovating with push-button toothpaste, "Electric Eye" whiteness testing, and a kids' line-building a full age-span portfolio. Today, Dr. West's artifacts and ads are housed by major museums, underscoring a legacy of science, innovation, and trust.
