Did you know?

The true ancestor of our toothbrush, however, was invented by the Chinese in the XVth century and brought back to Europe by travellers. This toothbrush was made of hairs from the neck of a Siberian wild boar which were fixed to a bamboo or bone handle. The people of the Occident, however, found the wild boar hairs too stiff. At the time, very few people in the Western world brushed their teeth, and those who did preferred horse hairs, which were softer than those of the wild boar! In Europe, it was more customary after meals to use a goose feather toothpick, or one made of silver or copper.

Other animals’ hair was also used for dental care, right up until this century. But it was the poor Siberian wild boar that took the brunt of it. The animal was imported for its neck hairs for a long, long time... in fact, until nylon was invented, in the XXth century!

In 1937, in the Du Pont laboratories in Nemours, U.S., nylon was invented by Wallace H. Carothers. In 1938, this new material became a symbol of modernism and prosperity through the commercialization of nylon stockings and of Dr. West’s miracle toothbrush with nylon bristles. The wild boars were finally off the hook!

At first, even if there were many advantages to using this new brush instead of the one made with wild boar hairs (which fell out, wouldn’t dry very well or became full of bacteria), the consumers were not entirely satisfied. This is because the nylon bristles were very stiff and hurt the gums. In 1950, Du Pont improved their toothbrush by giving it softer bristles.

Today the brands, types, and colours of toothbrushes on the market are almost endless. In spite of this, certain African and American populations still use tree branches to care for their teeth!

Well.. now you know.
