The toothbrush has come a long way. As the American Dental Association (ADA) notes, the earliest toothbrushes were actually small twigs people rubbed against their teeth to get rid of food bits and other pieces of debris. Over hundreds of years it evolved, beginning to feature bristles made from boar's hair. Finally, in the 1930s, DuPont de Nemours introduced toothbrushes made with nylon bristles, which people still use today.
Nowadays, though, there are plenty of additional choices when it comes to your toothbrush. You can use a hard toothbrush, a soft toothbrush, an electric-powered brush or a battery-powered brush.
