Today, everybody knows that we have to brush our teeth. But not too long ago, that was a new idea.

The first toothbrushes weren't made of plastic like the toothbrushes today are. Back in the 1800s, they were made of animal bones and hair. As you might imagine, they didn't work very well. In 1938, an American company made the first plastic toothbrush.

People started using floss a long time before they started brushing their teeth. Scientists have found teeth from humans who lived thousands of years ago that show that some of them flossed their teeth.

As for toothpaste, people have made it out of all kinds of different ingredients throughout history. In America in the 1700s, some people made toothpaste out of bread, and in the 1800s they made it out of charcoal! (Marc Langer, staff writer)
