20090241983 | Abrasive Dental Floss and Method of Making Same - Polytetrafluoroethylene (PTFE) flosses have abrasives added to the floss fiber that increase the abrasion to teeth surfaces, and thus result in a floss that provides enhanced cleaning of surfaces of teeth that face interstices between teeth. Floss fiber is formed by loading a PTFE resin with an abrasive filler. The PTFE resin and filler are processed to form a floss fiber with a surface that provide enhanced abrasion properties. | 10-01-2009 |
