Deep Penetration: Ultrasonic waves travel through water into areas a brush or tablet can’t reach, dislodging buildup from wire hinges, tiny grooves, and all the tricky corners. Your retainer or denture comes out visibly spotless.

Gentle Yet Powerful: Despite its intense cleaning action, ultrasonic cleaning is surprisingly gentle. There’s no scrubbing or abrasion – just bubbles doing the work. Your appliance won’t be scratched or warped. In fact, this method is so safe it’s used to clean jewelry and microchips without damage. No harsh chemicals or boiling water are needed, so the materials of your retainer stay intact.

From Harvard’s orthodontic clinics to King’s College London’s research labs, professionals have relied on ultrasonic cleaners to safely remove debris from dental tools for years. PurpleShield brings that trusted cavitation science right to your countertop, so you get a professional-level clean at home. All the visible gunk that causes bad breath and discoloration is blasted away in minutes – no elbow grease required.
