While it is necessary to brush your teeth often to maintain good oral hygiene, flossing is just as important. 

Brushing does not remove the food particles lodged between the teeth; only flossing can do this job.  Additionally, flossing helps prevent periodontal disease, improves gum health and reduces the risk of heart attack, stroke and diabetes. According to the American Academy of Periodontology, people with periodontal disease are almost twice as likely to have coronary artery (heart) disease.  One study even found that the presence of common problems in the mouth such as gum disease (gingivitis), cavities, and missing teeth were as accurate at predicting heart disease as cholesterol levels.
