Hello there. .., Brush your teeth after you eat. Keep a toothbrush at work to use after eating. Brush using a fluoride-containing toothpaste at least twice a day, especially after meals.... Floss at least once a day. Proper flossing removes food particles and plaque from between your teeth, Schedule regular dental checkups. See your dentist on a regular basis — generally once or twice a year....
