The elegant handle of the electric toothbrush 4900 enhances your brushing habits. It connects with the Oral-B app and provides real-time feedback for better brushing results. While you improve your brushing routine, Oral-B's unique round brush head takes care of the rest. It removes more plaque than a conventional manual toothbrush, promoting healthier gums and brightening your smile from the very first day of use by eliminating surface stains. Additionally, the toothbrush helps protect your sensitive gums with visual pressure control, reducing the brushing speed if you apply too much pressure.
