发明名称 Dental floss
摘要 A unique dental floss that is color coded to assist in its use. Alternate lineal sections of the floss are colored. The colored sections are waxed and the uncolored sections are unwaxed. The stronger colored sections are used to position the floss in the interproximal space while the more absorbent uncolored sections are used for the actual cleaning process.
