There is a reason why your dentist nags you about flossing daily. Proper flossing habits will help to removes plaque and debris that sticks to teeth and gums in between teeth, as well as help to controls bad breath. Plaque is a sticky layer of material containing bacteria, which builds up on your teeth, including places where toothbrushes can’t reach. This can lead to dental decay and gum disease. By ﬂossing your teeth daily, you reduce your risk of having dental decay and gum disease.
