Bad breath can be reduced or prevented if you:
Practice good oral hygiene. Brush twice a day with fluoride toothpaste to remove food debris and plaque. Brush teeth after you eat (keep a toothbrush at work or school to brush after lunch). Don't forget to brush the tongue, too. Replace your toothbrush every 2 to 3 months or after an illness. Use floss or an interdental cleaner to remove food particles and plaque between teeth once a day. Rinse with an antibacterial mouthwash twice a day. Dentures should be removed at night and cleaned thoroughly before being placed in your mouth the next morning.
