SteriSmile

SteriSmile makes a device that cleans dental retainers, aligners, mouthguards, and dentures using ultrasonic waves and UV-C light. Designed alongside dentists and orthodontists, it targets bacteria and biofilm that build up in microscopic grooves that regular brushing or soaking tablets can't reach. Each cleaning cycle takes about three minutes and requires no chemicals or scrubbing, making it safe for daily use on standard dental appliances. The UV-C bulb is rated for roughly 8,000 hours, or about ten years of daily use. The company ships within the US, offering free standard shipping and an optional expedited option at checkout.
