How Ultrasonic Waves Erase Biofilm Without Brushing
An ultrasonic retainer cleaner operates on a principle far removed from manual scrubbing or chemical soaking. Inside a compact basin, a transducer converts electrical energy into high-frequency sound waves—typically between 40,000 and 50,000 Hz. These waves create microscopic cavitation bubbles that implode with immense localized energy. The result is a gentle yet aggressive detachment of…
