Plaque is a bacterial film that forms on teeth between brushings. It produces an acid that gradually destroys tooth enamel. You may recognize it as a white goo or furry coating you can feel on your teeth after a meal or eating a candy bar. Left untreated, plaque hardens into tartar, a crunchy mortar that damages teeth and gums. Regular brushing helps control plaque growth, but a little neglect can result in a biofilm coating of plaque that's resistant to brushing. Flossers have plaque-busting tips with soft bristles to get into hard-to-reach spots between teeth and scrub away plaque without damaging the surrounding gums. They also use water pressure to break up biofilm and plaque buildup. Plaque seeking tips are particularly effective at removing build up around dental restorations like bridges, crowns and implants.
