The HT-B223/224 electric toothbrushes ease the anxiety of first-time users and people who fear the strong vibration of electric brushes. The sonic vibration is soft on gums and removes plaque three times more effectively than brushing by hand. The three-dimensional motion of the brush combines vibrations in the vertical and horizontal directions to more effectively brush the gaps between teeth and the recesses on top of teeth. The slim body can easily be rinsed and provides a comfortable grip.
