M-series (1954)

The first bristle toothbrush, resembling the modern toothbrush, dates back to the Tang Dynasty (619–907). The first patent for a toothbrush was granted to H. N. Wadsworth in 1857 in the United States. It had a bone handle with holes bored into it for the Siberian boar hair bristles. Unfortunately, animal bristle was not an ideal material as it retains bacteria and does not dry well, so the bristles often fell out. During the 1900s, celluloid handles gradually replaced bone handles in toothbrushes. Natural animal bristles were also replaced by synthetic fibers, usually nylon, by DuPont in 1938.

Lactona has been on the forefront of nylon filament technology since Dupont developed the very first nylon filaments in 1938. Lactona as a brand name was first used for a toothpaste developed by a dentist in the USA in 1931. In 1954 Lactona started with the production of the M39 toothbrush. This toothbrush with a signature rubber tip, which is used to stimulate the gums, was the first multi tufted toothbrush and gave Lactona instant brand identification.
