Toothbrushes have been around for hundreds of years. In fact, the first known toothbrushes were used about 5,000 years ago and were made of twigs. The Prophet Mohammed introâ¦duced the use of the miswak (toothbrush) to the middle east about 1,300 years ago.
The first electric toothbrush, the Broxodent, was invented in Switzerland in 1954. As of the turn of the 21st century, nylon had come to be widely used for the bristles, and the handles were usually molded from thermoplastic materials.he bristle toothbrush spread to Europe, brought back from China to Europe by travellers. It was adopted in Europe during the 17th century.
