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. The versatile nylon loop design of floss threader fits all types of floss and helps thread the floss where most other products cannot reach.
