Abstract: 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.

Abstract: Tooth whitening compound includes a whitener and a carrier selected for adhering the carrier and whitening composition to a user's teeth. The whitening compound may be applied by the method including painting, washing, sponging, coating, daubing, spraying, wiping, rubbing, and by any movement relative to a horizontal or vertical axis of the user's tooth. The whitening compound may be sufficiently viscous to adhere to a user's teeth, in use, without a mechanical retaining device. The whitening compound may be a semi-solid or a solid compound at ambient temperatures.
