So why is flossing so important? Well, it all begins with the small food particles can easily get lodged in the gaps between your teeth and below the gum line.When you brush your teeth, you scrub bacteria, plaque and food particles off the chewing surfaces and visible sides of your teeth. But a regular toothbrush can’t reach the tight spaces between your teeth and under your gums. This is why you need to do some kind of interdental (between-teeth) cleaning, too.If you don’t thoroughly clean plaque from your teeth, it hardens over time and forms a substance called tartar. This thick deposit can’t be removed by brushing or flossing teeth; only dentists can dislodge it with specialist tools during a scale and polish (and the process isn’t exactly pleasant).
