The Harp Orthodontic Flosser is the ultimate tool for flossing with braces. The Harp Flosser is designed to reach behind the arch wires of braces for easy flossing and uses braided nylon thread which is much stronger than typical dental floss. Each Harp Flosser is reusable, and lasts about a week, making it much more sustainable than traditional single use floss picks. Just rinse and store in the handy “Go-Tainer” for sanitary storage.
