The 48kHz high-frequency ultrasonic technology vibrates water, generating countless bubbles, and the shock waves from the moment those bubbles burst penetrate even the tiniest gaps, thoroughly removing invisible sebum and stubborn dirt from all 360°! Gentle water washing does not damage delicate materials and there is no risk of corrosion. No need for troublesome soaking, it cleans quickly and refreshes unpleasant odors at the same time. Compatible with all oral devices such as dentures, prosthetics, night guards, mouthpiece orthodontic appliances, and retainers.
