What Is an Ultrasonic Cleaner for Retainers?
An ultrasonic retainer cleaner uses 45,000 Hz sound waves to create millions of microscopic bubbles that remove bacteria, plaque, and biofilm from every surface of your retainer — including the tiny crevices that a toothbrush can't reach. Our cordless ultrasonic dental retainer cleaner also includes built-in UVC sterilisation, killing 99.97% of germs in minutes without chemicals or tablets.
