The Electric Toothbrush

An electric toothbrush is a special kind of toothbrush. It has a motor inside that moves the bristles for you. Some spin around in circles, while others shake very fast. These brushes can clean teeth better than regular ones.

How They Work

Electric toothbrushes run on batteries you can charge up. When you press a button, the head starts moving quickly. You just hold the brush in place and guide it across your teeth. Many have timers that beep every 30 seconds. This helps you brush each part of your mouth long enough.

When They Were Invented

The first electric toothbrush was made in 1954 in Switzerland. It was created to help people who had trouble using their hands. Soon, everyone wanted one because they worked so well. Early ones had to be plugged into a wall while brushing. Today's electric toothbrushes are cordless and charge on a little stand.
