We really like this floss because it is easy to use and very effective. Listerine Ultraclean dental floss stretches and flexes, sliding easily between teeth for hassle-free cleaning. This tough, shred-resistant dental floss uses Micro-Groove technology to remove plaque. This is much more effective than competing smooth flosses. Flossing removes plaque on teeth that brushing may miss and is an important step in your oral care routine. The shred resistant composition makes it really easy to use around dental restorations which would normally shred or tear floss.
