Daily tooth brushing along with flossing are the most important actions you can take to ward off bad breath. According to the American Dental Association (ADA), if you neglect to brush and floss daily, food particles can linger in your mouth, causing bad breath. So, it's recommended to brush two times a day for at least two minutes.
Today, flossing has become an integral part of daily oral care and the American Dental Association recommends you floss once daily at least. Correct flossing after each meal consistently cuts down on plaque, bacteria and odor-causing food particles. Flossing helps stop periodontal disease as well, another cause of bad breath.
