A fine, waxed, flavorless dental floss that has been impregnated with chlorhexidine is Elgydium Clinic Black Dental Floss With Chlorhexidine. Because it is dark, it is easier to notice the removed plaque. Those with exposed tooth necks, implants, or braces must take extra care to maintain proper dental hygiene. Dental floss or interdental brushes are essential for helping to remove food particles and dental plaque that have been lodged between teeth. By removing food particles and stopping plaque buildup, flossing daily can reduce your risk of gum disease and tooth decay. Elgydium Black Dental Floss, which is coated in chlorhexidine, helps to lessen gum bleeding as well as gum swelling and inflammation (redness).
