GUM® Eez-Thru® floss threaders are designed to thread dental floss under orthodontic braces, fixed bridges and dental implants. These dental appliances and fixtures are often considered by dental professionals to be plaque traps that require additional cleaning effort. If not cleaned as part of a daily oral hygiene routine, buildup of dental plaque may compromise the health and longevity of the appliance as well of the surrounding natural teeth. Threading dental floss under, around and between orthodontic braces, fixed bridges and dental implants is almost impossible without the assistance of a floss threader.
