Floss for orthodontic appliances
Orthodontic appliances, such as brackets, wires, and bands, can harbor plaque with more virulent changes in bacterial composition, which can ultimately cause a reduction in periodontal health as indicated by increased gingival recession, bleeding on probing, and plaque retention measurements. Furthermore, fixed appliances makes plaque control more challenging and restricts the natural cleaning action of the tongue, lips, and cheek to remove food and bacterial debris from tooth surfaces, and also creates new plaque stagnation areas that stimulate the colonisation of pathogenic bacteria.
Patients undergoing orthodontic treatment may be recommended to maintain a high level of plaque control through not only conscientious toothbrushing, but also proximal surface cleaning via interdental aids, with dental floss being the most recommended by dental professionals. Notably, small-scale clinical studies have demonstrated that dental floss, when used correctly, may lead to clinically significant improvements in proximal gingival health.
A floss threader is loop of fiber that is shaped in order to produce better handling characteristics. It is (similar to fishing line) used to thread floss into small, hard to reach sites around teeth. Threaders are sometimes required to floss with dental braces, fix retainers, and bridge.
