Dental floss coating is a WAX-like substance that is applied to dental floss to make it easier to use and more comfortable for the user. It helps to reduce friction between the floss and the teeth, making it easier to slide between them. The WAX also helps to protect the gums from irritation and helps to keep the floss from breaking or fraying. The most common type of WAX used for this purpose is beeswax, although other types of waxes can also be used.
