How to brush your teeth with an electric toothbrush is correct.

1. Wet the electric toothbrush head first, and then apply toothpaste to the bristles. The amount of toothpaste should be the same as when using a traditional toothbrush. Don't reduce the amount of toothpaste just because the toothbrush head is smaller.

2. Then, when brushing your teeth, pass the brush head through the thinnest front teeth. Let the teeth be sandwiched between three bristles and pull back and forth with moderate force. Turn on the electrical switch when the toothpaste bubbles. After the brush head vibrates, move the toothbrush back and forth from the front teeth with moderate force, and brush the external teeth first and then the internal teeth. Then put the upper and lower toothbrushes on the occlusal surface and brush all the teeth clean.

3. Finally, clean the toothbrush bristles: after each brushing, put the brush head into the water, turn on the electric switch and shake it a few times, then pat the brush head to clean the foreign matter and toothpaste left on the bristles.
