You might think that if you brush your teeth thoroughly and have no food trapped between your teeth you don’t need to floss. Actually, flossing is imperative because it helps you get rid of plaque from between the teeth, where a toothbrush can’t reach. Taking care of your teeth and gums is important in avoiding tooth decay and periodontal disease, which may lead to bone loss. One way you can lose teeth is by not brushing and flossing regularly.
