PROBLEM TO BE SOLVED: To provide an oral cavity care device for performing the imparting operation of ultrasonic vibration and the application operation of a low frequency current to the same part.SOLUTION: The oral cavity care device 1 is provided with: a body 5 provided with a grip part 51; a vibration imparting part 2 which is extended to one end of the body 5 and imparts ultrasonic vibration to the inside of the oral cavity; a low frequency current generation part 63 for generating a low frequency current; and at least a pair of electrodes for applying low frequency current to the inside of the oral cavity. The vibration imparting part 2 includes: an ultrasonic vibrator 3 for performing ultrasonic vibration; and a vibration transmission horn 4 for transmitting the generated ultrasonic vibration to the inside of the oral cavity. The vibration transmission horn 4 also functions as one of the pair of electrodes of the low frequency current generation part 63. Thus, it is possible to perform the imparting operation of the ultrasonic vibration and the application operation of low frequency current to almost the same part without replacing devices nor changing the way of holding the grip part 51. |
