ABSTRACT:
A teeth cleaning apparatus has a brush pivotally mounted in a brush holder. The brush has a teeth cleaning member such as bristles formed thereon. A vibrator exerts a vibratory force on the brush so that the teeth cleaning member moves back and forth in substantially its axial direction. The vibrator is driven by an electrical signal which preferably is of a frequency between 1,000 and 17,000 Hz and includes an audio frequency component of mixed frequency and amplitude representing music or other pleasant sounds which is transmitted to the auditory system of a person while brushing.
