The Same, But Different
While each electric toothbrush looks similar, each brand has unique features to appeal to different users. Some have heads that rotate or oscillate, and others use ultrasonic technology to break up plaque and food debris. Some have timers that beep at certain intervals, and others have multiple settings for specific issues like massaging your gums or stopping the brush head when you're brushing too hard.
But each model offers the same benefit: The ability to gently hold the brush in place while the motor and bristles do the hard work of cleaning the teeth.
