GUM Ortho Floss

GUM brand dental products, specifically the Ortho Floss shown, are part of a legacy that began in the United States with the invention of the rubber-tipped stimulator by Dr. John O. Butler in 1923. The brand, which stands for 'Gentle Oral Care,' has evolved into a global leader in specialized oral hygiene products, particularly those designed for orthodontic maintenance and interdental cleaning. Today, GUM products are manufactured in various facilities around the world, including the United States, Europe, and Asia, to serve a global market.

The GUM brand is owned and operated by the Sunstar Group, a Japanese multinational corporation. Sunstar acquired the John O. Butler Company in 1988, integrating the American brand's clinical expertise with Japanese quality standards and global distribution networks. Sunstar remains the ultimate owner, managing the brand through its global headquarters in Switzerland and regional subsidiaries such as Sunstar Americas and Sunstar Europe. The product packaging highlights modern sustainability efforts, utilizing recycled PET and paperboard.
