Retainer Fresh is a dental-care brand focused on making it easier to keep removable dental appliances clean, fresh, and ready to wear. Its core product is a fizzy cleaning tablet designed for retainers, clear aligners, nightguards, mouthguards, splints, and dentures. Users place an appliance in water with a tablet and allow it to work for five to fifteen minutes; the tablets can also be used with ultrasonic cleaners.

The brand highlights a minty-fresh formula, individually sealed tablets, and cleaning performance aimed at reducing odours and stains. Products are sold in packs of 36 or 120 tablets, described as approximately one-month and four-month supplies with daily use. Retainer Fresh sells directly through its online store and provides product information, customer support, and resources for dental professionals.

The company also offers a 30-day money-back guarantee. Its messaging centres on convenient appliance care and helping customers feel more confident about wearing and smiling with their dental devices
