摘要：
Tooth whitening device for whitening teeth using sonochemistry includes a body, and an ultrasonic transducer provided in the body. The ultrasonic transducer is configured for producing ultrasonic waves in the range of 20-100 kHz, and good results have been achieved with ultrasonic waves at a frequency of 40 kHz. There is an ultrasonic horn provided on the body, and the ultrasonic horn is operatively connected with the ultrasonic transducer. A liquid retaining element is provided on the ultrasonic horn, and the liquid retaining element is configured for retaining a liquid tooth whitening composition against a user's teeth. The liquid retaining element may be a sponge or a replaceable pad, such as a foam pad.
