ABSTRACT:
A new and improved dental floss having a relatively large diameter to provide an increased surface area, and comprised of a multitude of fibers overlaid upon each other such that a number of the fiber ends extend beyond the main body of the dental floss and are somewhat self-supporting. The dental floss has improved cleaning ability and increased shock absorbency which lessens discomfort to the user.
