Electric toothbrushes are powered by an electric motor that creates rapid movements to help clean teeth more effectively than manual toothbrushes. Let's take a closer look at how electric toothbrushes work step by step.

**Step 1: Power Source**.

Electric toothbrushes are usually powered by rechargeable batteries. When the toothbrush is turned on, the batteries provide the necessary energy to the electric motor that drives the brush head.

**Step 2: Electric Motor**.

The electric motor in an electric toothbrush is responsible for generating rapid movements in the brush head. These movements can vary in speed and motion, depending on the model of the toothbrush. The motor is typically housed in the handle of the toothbrush.

**Step 3: Brush Head**.

The brush head of an electric toothbrush is where the bristles are located. The rapid movements generated by the electric motor cause the bristles to oscillate, rotate, or vibrate, depending on the design of the toothbrush. These movements help to dislodge plaque and food particles from the teeth and gums.

**Step 4: Cleaning Action**.

As the bristles of the electric toothbrush move back and forth or rotate, they create a scrubbing action that helps to remove plaque, bacteria, and food debris from the tooth surfaces and gum line. This cleaning action is more effective than manual brushing, as the movements are quicker and more consistent.

**Step 5: Timer and Sensors**.

Many electric toothbrushes come with built-in timers and sensors to help users brush their teeth for the recommended amount of time and with the right pressure. Timers usually signal when the user should switch to a different quadrant of the mouth, ensuring that each area gets equal attention. Pressure sensors alert users when they are applying too much force while brushing, which can damage the gums and enamel.

In conclusion, electric toothbrushes work by using an electric motor to create rapid movements in the brush head, which in turn provides a more effective cleaning action than manual toothbrushes. With the added features of timers and sensors, electric toothbrushes help users maintain good oral hygiene practices for healthier teeth and gums.
