ABSTRACT:
A power flosser tip incorporating a tooth-whitening coating. The coating is typically abrasive, and whitens teeth by scraping or wearing down hardened plaque or other tooth discolorations. The coating may also whiten teeth through a chemical reaction. The coating may be flavored in order to enhance user enjoyment. The coating is chemically bonded to the flosser tip, and dissolves when in contact with saliva or water at room temperature and pressure.
